Personality

Hashiba Hikaru’s overall demeanor is one of deliberate calm and collected composure, masking a deeply analytical and strategically calculating mind. He approaches interpersonal relationships—particularly the complex web of romantic entanglements he cultivates—with the detached precision of a chess player, yet he is also capable of genuine warmth, protectiveness, and consideration for those he cares about. This duality allows him to navigate high-stakes social situations almost effortlessly, maintaining an unruffled exterior even when confronted with jealousy, accusations, or outright hostility.

• Calm and Composed: Hashiba Hikaru consistently maintains his composure under pressure, rarely showing guilt, concern, or panic even when directly accused of deception or deceit. When Hasebe Haruka confronts him about allegedly deceiving Sakura Airi, he shows no signs of guilt or concern, instead remaining collected and measured throughout the encounter 237. Similarly, during Kushida Kikyo’s aggressive advances in a movie theater, he remains unfazed, demonstrating maturity and self-control 420. This tranquility extends to handling rumors; when a viral forum post spreads gossip about his relationships, he remains unaffected while the girls mentioned struggle with the fallout 224 364.

• Analytical and Manipulative: Hashiba Hikaru is a keen observer who evaluates people strategically, often viewing them through the lens of his system and stock prices. He mentally notes Kushida Kikyo’s social-butterfly nature and immediately deduces she is not simple 20. He plans his interactions carefully, knowing that different girls require different approaches to cultivate relationships 197. His actions are often executed from a self-interested perspective, and he is aware of his own manipulative tendencies, acknowledging that many of his thoughts are driven by greed 360 593. He uses his [Stock Analyzer] to gather information and deliberately steers conversations to probe weaknesses, such as when he tests Kushida by mentioning Horikita Suzune to gauge her reaction 33.

• Caring and Considerate: Despite his calculating nature, Hashiba Hikaru shows genuine care and respect for the feelings of the girls in his life. He is considerate of Ichinose Honami’s feelings, valuing their relationship and her happiness, and he reassures her when she feels jealous or insecure 241 239. He sends a thoughtful message to Sakura Airi to cheer her up after she is left out of a rumor 224. He also shows patience and gentleness with shy girls like Sakura, deliberately treating her with utmost gentleness until a relationship of trust is established 47. He even offers to buy drinks for friends as a considerate gesture 286.

• Protective: Hashiba Hikaru is willing to take decisive action to protect those he cares about. When Sakura Airi is targeted by a stalker, he confronts the man and beats him up, significantly increasing her trust in him 53. He also physically threatens Amasawa Ichika by grabbing her throat to interrogate her about a sensitive matter, displaying a severe and cold side when the situation demands it 438 723. This protectiveness is not limited to physical threats; he also safeguards Kushida Kikyo’s emotional well-being by accepting her past without judgment 235.

• Honest and Responsible: Hashiba Hikaru values honesty and responsibility in his relationships, especially when faced with difficult confessions. When Shiina Hiyori confesses her feelings, he acknowledges her emotions but honestly expresses his commitment to his current relationship, demonstrating responsibility and sincerity 206. He tells Ichinose Honami the truth about his friendship with Sakura Airi, even when it is uncomfortable, and he promises to respect everyone’s feelings while pursuing his unique relationship style 241 286. He also takes responsibility for his actions, admitting that he cannot bear to let go of any of the girls he has bonded with 360 593.

• Self-Aware and Greedy: Hashiba Hikaru is acutely aware of his own flaws and motivations, particularly his greed. He recognizes that, after activating the system, his thoughts and actions have been executed from a self-interested perspective, and that he “cannot bear to let go of anyone” because “people are greedy; everyone wants to possess beautiful things” 593. He admits this internally without self-deception, and he is aware that his initial plans have fallen through because of his inability to sacrifice relationships 360.

• Strategic and Calculating: Hashiba Hikaru operates with a long-term strategic vision, using tools like [Foresight Moment] to lock onto targets such as Nagumo Miyabi and learn the specific timing of his plans 336. He carefully manages his energy and time, even assessing which girls are easier to handle and which require more effort, acknowledging that he currently lacks the energy to deepen ties with some 360. He also deliberately minimizes his presence when necessary, such as quietly dressing and leaving early in the morning to avoid disturbing sleeping girls 259.

• Playful and Teasing: When comfortable, Hashiba Hikaru displays a playful, teasing side, especially with girls he is close to. He teases Ibuki Mio about her protectiveness toward Shiina Hiyori 220. With Kushida Kikyo, he engages in flirtatious banter, such as when he jokes about knowing how to swim even if she tied a rock to him, and he smiles while saying he doesn’t dislike her intense personality 197. He also cooperates with her when she acts spoiled, using a gentle attitude to coax her, understanding that she appreciates boundaries 507.

• Severe and Cold When Necessary: Hashiba Hikaru can switch from gentle to severe in an instant when the situation demands authority or intimidation. When interrogating Amasawa Ichika, his gaze turns sharp and his tone commanding, causing her heart to race uncontrollably 446 721. He grabs a red-haired underclassman by the throat and pins her against the wall to extract information, a side of him that shocks even Kushida Kikyo, who has never seen him use force against a girl before 438. This coldness is a tool he wields deliberately, and it elicits a fearful yet fascinated reaction from those on the receiving end.

Power Progression

Relationships

Ichinose Honami

Ichinose Honami is Hashiba Hikaru’s official girlfriend and the emotional anchor of his romantic life. From the beginning, their relationship is defined by mutual trust and open communication, though it is repeatedly tested by Hikaru’s involvement with other girls. Early on, Honami demonstrates a calm, secure demeanor—when she learns of other girls calling Hikaru on a Saturday morning, she remains collected and does not press the issue 226. However, her jealousy surfaces when she sees Hikaru with Kushida Kikyo in the supermarket 239, and she becomes increasingly aware of the other women in Hikaru’s life, such as Horikita Suzune and Sakura Airi, whose closeness to him she finds unsettling 284 376. Despite this, Honami chooses to trust Hikaru and refrains from forcing him to cut ties with anyone 387. The most significant development in their relationship comes when Hikaru confirms his involvement with Kiryuuin Fuuka. Honami is heartbroken but ultimately accepts it, agreeing to a three-person relationship with Kiryuuin 480 506. She then asserts her boundaries by asking Hikaru to promise not to exceed seven partners and to ensure she is the only one who can become pregnant, terms to which he agrees 480. Honami also takes a proactive, sometimes secretive role in guarding their relationship: she records Hikaru’s interactions with Kushida and plans covertly 328, and she invites Sakura Airi to her dorm to question her about a song linked to Hikaru, with Kushida unexpectedly joining 287. Her role as “main girlfriend” carries significant pressure—she is described as gentle, considerate, and virtuous, capable of helping Hikaru in many ways, but also burdened by the need to manage the dynamics of his harem 288 360. She even coordinates with Kiryuuin Fuuka as a partner and forgives Kushida after a heart-to-heart talk, showing her capacity for compromise 331 493.

Kushida Kikyo

Kushida Kikyo is one of Hashiba Hikaru’s lovers, characterized by her jealousy, possessiveness, and strategic maneuvering to secure her position. From early on, she flirts with Hikaru openly—changing her perfume and playing under his desk in his office 831—and she becomes increasingly bold in expressing her affection, even in public settings 226. She is acutely aware of Hikaru’s other relationships and frequently acts on her jealousy. When she detects Horikita Suzune’s scent on Hikaru, she angrily confronts him, and she later becomes hostile toward Horikita, demanding explanations about their relationship 297 347. Kushida also targets Sakura Airi, inviting her to dinner to win her over as an ally, exploiting her knowledge of their secret relationship 229. Despite her jealous streaks, Kushida shows a softer side: she comforts Sakura Airi after Ichinose Honami’s questioning, acknowledging the pressure the “official girlfriend” bears 288. She also expresses her love and desire for Hikaru during intimate time together 328. Her relationship with Hikaru is built on honesty—he shares sensitive matters with her, such as his plans regarding Ayanokoji Kiyotaka, and she is the only one besides a select few who knows certain secrets 453. Yet she feels slighted when Hikaru appoints Horikita as chair of the Disciplinary Committee, leading to a clash where Hikaru explains that Horikita is more suited for the role 375. Kushida’s persistence and underlying insecurity are evident; she demands promises of unconditional love and becomes upset when Hikaru discusses plans for Sakura Airi’s future 214. Ultimately, she comes to accept the polyamorous arrangement after Hikaru explains that Honami allows it, though she remains competitive and watchful 387.

Horikita Suzune

Horikita Suzune’s relationship with Hashiba Hikaru evolves from a cold, partnership-based dynamic to a fully romantic one. Initially, she is distant and reserved, but after Hikaru helps her, she expresses gratitude and begins to rely on him more, with her “stock price” rising to 100 as a sign of their growing closeness 226. She becomes more assertive in pursuing personal goals, such as asking Hikaru to guide her in cooking 331, and she shows concern for his well-being, offering to help clear Ichinose Honami’s name during a slander incident 321. Their relationship deepens further when they officially become a couple—Horikita confirms her feelings, and her stock rises to 200 297. Despite her cold exterior, Horikita displays jealousy: she coldly observes Hikaru embracing Kushida in her dorm and reacts with a “slightly sour” expression 186. She also takes on a significant role as chair of the Disciplinary Committee, a position Hikaru chooses for her because of her personality and abilities, which causes tension with Kushida 375. Horikita’s relationship with Hikaru remains somewhat less intimate than his others—they haven’t done anything “too intimate yet” 360—but she is trusted with important tasks and collaborates closely with him on strategies for Special Exams, alongside Ichinose Honami 830. Her growing feelings are noted by others: Kushida suspects she is one of Hikaru’s lovers, and Hikaru himself acknowledges that she is “different” from other girls, being meticulously obedient without questioning deeper reasons 327 453.

Sakura Airi

Sakura Airi is a quiet, secretive lover of Hashiba Hikaru, known for her deep emotional connection to him. She confesses her love story to Hasebe Haruka, revealing the depth of her feelings 239. Hikaru wrote a song for her, which becomes a point of intrigue for Ichinose Honami, who invites Sakura to question her about it 287. Sakura feels immense pressure as a “thief” who has stolen Hikaru’s love, especially when facing his official girlfriend, Honami 287. Her relationship with Hikaru is kept hidden from most, and she struggles with the secrecy—she has not met with him privately since winter break due to concerns about Honami’s awareness 288. Kushida Kikyo sees Sakura as a potential ally and tries to manipulate her, inviting her to dinner and exploiting her lack of social experience to learn about her relationship with Hikaru 229. Despite this, Sakura remains loyal to Hikaru and shows determination to keep their relationship, though she is easily overwhelmed by social interactions, as seen when she retreats to solitude after group outings 47 83. Hikaru is also concerned about her future, discussing plans for her career with Kushida, which triggers Kushida’s jealousy 214. Sakura’s role in the harem is that of a quiet, devoted partner who loves Hikaru deeply but is constantly anxious about exposure and judgment.

Kiryuuin Fuuka

Kiryuuin Fuuka is a third-year senior who becomes involved with Hashiba Hikaru as a partner, specifically in a three-person relationship that includes Ichinose Honami. Her relationship with Hikaru is initially distant due to limited opportunities for contact, but she develops a rapport with Honami, as they are the only two who have acted in tandem 360 493. Kiryuuin is instrumental in bringing Honami into the dynamic—she insists that Honami is already aware and accepting of the arrangement, and Hikaru agrees to wait for Honami’s decision 506. In conversations, Kiryuuin teases Hikaru about Horikita Suzune, which causes Honami some unease, but Honami ultimately accepts her as a partner 210. Kiryuuin’s role is more peripheral compared to the other girls; she does not have the same level of intimacy or frequency of interaction, but she is acknowledged as one of Hikaru’s lovers by the narrative and by other characters, such as Kushida, who lists her among the “others” 327.

Sakayanagi Arisu

Sakayanagi Arisu’s relationship with Hashiba Hikaru is described as a “cooperative partnership” by Hikaru himself, though others suspect deeper involvement. Kushida Kikyo explicitly accuses Hikaru of having a “deep connection” with Sakayanagi, but he denies it, claiming they are merely business partners 327. The narrative hints at more: Sakayanagi cancels a planned chess match and reveals she has important information to share, and she is later seen meeting with Hikaru and Kamuro Masumi in a secluded classroom, suggesting secretive interactions 214. Hikaru also shares sensitive information with her, including his plans regarding Ayanokoji Kiyotaka, indicating a high level of trust 453. However, their relationship lacks the romantic intimacy of his other liaisons; they have not done anything “too intimate” 360. Despite this, Ichinose Honami considers Sakayanagi a potential rival, listing her among the girls Hikaru might be involved with 493. Sakayanagi’s true position remains ambiguous—she is a close ally and confidante, but not officially a girlfriend.

Shiina Hiyori

Shiina Hiyori is a peripheral figure in Hashiba Hikaru’s romantic network. She is mentioned as one of the girls with whom Hikaru might have an intimate relationship, but their interactions are limited. Ibuki Mio confronts Hikaru, asking him to break up with Ichinose Honami for Shiina’s sake, which he refuses, leading to a tense argument 221. This suggests that Shiina has feelings for Hikaru and that others are aware of it. However, Hikaru himself notes that Shiina seems “more distant” and that there are few opportunities for contact, indicating that their relationship has not developed into a full romantic connection 360. Ichinose Honami also lists Shiina among the girls she is wary of, but acknowledges she can barely hold a conversation with her 493. Shiina’s role remains minor—she is a potential love interest whose relationship with Hikaru is unresolved.

Plot Role

Hashiba Hikaru’s overarching goal is to consolidate absolute control over the school’s power structures, using the Student Council as his primary instrument. From his first year, he recognizes that the Student Council is the key to influence, and he strategically avoids early membership to preserve his freedom while secretly securing guaranteed admission spots for his allies 73. Once he joins and becomes Vice President, his ambitions sharpen: he intends to finish off Nagumo Miyabi within the third semester and take full control of the Council, believing that only as Student Council President can he establish a closer connection with the Chairman and handle issues more quickly 281. His plans extend beyond mere authority — he aims to use the Council’s power to maintain the school’s atmosphere, resolve threats from the White Room and Ayanokoji’s father, and ultimately lead his class to total victory within the existing rules 452. This long-term vision drives his every political move, from purging rivals like Higashida Takashi to planting loyalists like Kushida Kikyo in executive positions 264 267.

Within the school’s social hierarchy, Hashiba Hikaru rises from a shrewd first-year newcomer to the undisputed apex of student power. He is recognized early by outgoing Student Council President Horikita Manabu as a potential rival to Nagumo Miyabi, earning the senior’s backing and access to insider information 10 27 76. His rapid ascent is fueled by a combination of sharp political acumen, vast network-building, and the ability to outmaneuver opponents — he wins the Vice Presidency by a landslide, beats Nagumo’s candidate in a subsequent Council election, and is widely expected to become Student Council President by the end of his first year 194 267 290. His influence permeates every layer of the school: he recruits and mentors many key figures (including Horikita Suzune, Kushida Kikyo, and Shiina Hiyori), brokers alliances with class leaders like Sakayanagi Arisu and Ryuen Kakeru, and even earns the secret support of senior students such as Kiryuuin Fuuka and Asahina Nazuna 173 204 217 267. By the start of the second year, he has already assumed the Student Council Presidency and uses his opening ceremony speech to warn freshmen about the Disciplinary Committee while announcing recruitment, signaling his intention to shape the entire student body’s conduct 426 427. His significance in the plot is thus twofold: he is both the architect of a new, centralized power structure and a key player facing down external threats (White Room, Chairman’s affairs) that could destabilize the school. The story repeatedly frames his decisions — whether expelling a troublesome student like Hosen or choosing to cooperate with Ayanokoji — as turning points with school-wide consequences 458 281.
