Jilan

Biodata

Power Progression

Background

Jilan remembers a previous life as an office worker, including knowledge of several languages and JoJo’s Bizarre Adventure. He recognizes the resemblance between his name, powers, and Yoshikage Kira, but conceals Killer Queen because of its lethality 2 62.

His adoptive parents died before his first year of junior high, leaving him to live alone. A teacher arranged his movie-theater job; government compensation and part-time work supported him, while online translation brought in substantially more money. The theater job also provided a cover for his income and an opportunity to observe the relationship between heroes and the public 3 13 62.

All Might’s example helped inspire his ambition to become a hero. Jilan also hoped that contact with more Pro Heroes might reveal a way to counter the disturbing influence associated with Killer Queen 13.

Appearance

• Blond hair and deep-set eyes: These features are noted when he returns to Qiyuan Inn with Fran 379.
• Shorter than Momo Yaoyorozu: She teases him about their height difference during the Sports Festival race 108.
• Rescue-oriented combat clothing: Wears a firefighting suit for rescue work 34.
• Red pupils under strain: His pupils take on a blood-red hue during his match against Todoroki 138.

Personality

Jilan is outwardly composed, sarcastic, and reluctant to compete without a practical reason. Even as a hostage, he criticizes his captor’s handling of the situation. Bakugo interprets his lack of competitive enthusiasm as unfitness for hero work, while Jilan insists that he wants a peaceful life 1 20.

His caution can conflict sharply with conventional heroism. In Hosu, he recognizes that Kurogiri intends to strand him at the battle and make his unexplained arrival look suspicious. He checks the Warp Gate’s destination, restrains Kurogiri, and watches rather than intervening. The decision protects him from the trap but deepens the League’s belief that he belongs among villains 190 191.

Despite this self-preservation, Jilan repeatedly protects and treats classmates, refuses the League’s invitations, and rejects the idea of becoming a bad person. His attachment to Fran develops especially quickly: he goes from considering her useful for experiments to finding genuine fulfillment in being called “Papa” 41 236 377 420.

Killer Queen complicates his sense of identity. He experiences an increasing fixation on hands and destructive urges, alongside a cold analytical state that suppresses ordinary emotion. Although that state improves his fighting, he fears losing the emotions that make him himself 13 142.

Abilities & Skills

Hamon

Hamon is life energy generated through breathing. Jilan uses it to reinforce his body, recover his condition, and produce different effects through different media 2 140 400.

• Physical reinforcement: Enhances strength and speed; his Hamon-covered movement is faster than the fleeing magician’s 236 411.
• Continuous operation: By the forest training camp, he keeps Hamon active subconsciously whenever he can breathe, with energy recovering through respiration 400.
• Energy management: Before taking the Stock Solution, he must balance attack strength against his finite Hamon reserves 364.
• Control: Gathering Hamon rather than allowing it to scatter reduces wasted energy and permits focused attacks 48.

Healing and Diagnosis

Hamon accelerates natural healing by increasing cellular activity. Recovery Girl distinguishes this from her own Quirk, which can exhaust a severely injured patient by forcing rapid cell division 97.

• Warms and treats Hagakure after Todoroki freezes her 25.
• Examines Midoriya’s injuries and warns that repeated overexertion can cause lasting damage 133.
• Detects drugs, corrosive chemicals, and ambergris traces inside Little Red Riding Hood 305.
• Breaks down poisonous mist absorbed by Ibara’s vines, clears Yaoyorozu’s hallucinations, and revives Ibara 407.
• Rapidly heals his shoulder wound, though he temporarily loses use of the injured arm 417.

Resistance to Harmful Effects

By covering his body with Hamon, Jilan resists harmful conditions and Quirk-induced alterations. He describes petrification, slowing, stunning, and brainwashing as effects that fall within this protection 48 122.

• Decay: Shigaraki’s Quirk cannot affect him while protected 236.
• Brainwashing: Deliberately answers Shinso, remains unaffected, and pretends to be controlled 122.
• Poison: Operates inside the forest’s dense purple mist without a gas mask 407 411.
• Compression: Cancels the Compress Quirk on Ragdoll’s marble, restoring her body 420.
• Limits: This protection does not prevent all physical injury; Bakugo’s explosions and a Nomu’s blade still injure him 140 417.

Hamon Techniques

Killer Queen

Killer Queen turns substances touched by Jilan’s fingers into bombs. He hides it behind his publicly declared Hamon Quirk 2 49.

• Detonation modes: Bombs can trigger through another person’s contact or Jilan’s remote command. Either trigger can produce an outward explosion or an implosion confined to the bomb itself 49.
• Selective destruction: Can preserve the bomb object, destroy it, or leave it partly intact 49.
• Remote triggering: His hand serves as a detonator, with no distance restriction stated for triggering a prepared bomb 49.
• Object size: Small, separate objects can be converted completely. On large structures such as walls, only the touched portion becomes a bomb; a distinct component such as a doorknob can still be converted in full 49.
• First Bomb limit: Only one such bomb can exist at a time; he must detonate it before preparing another 49.
• Living targets: Ordinary contact works on Quirkless people and people with body-altering Quirks. Those with externally acting “superpower” Quirks generally must be unconscious, asleep, or otherwise not consciously resisting 49 236.
• Unavailable effects: He does not initially possess Bites the Dust or the original Killer Queen effect in which a touched bomb destroys the person contacting it instead of exploding itself 49.

Frequent use aggravates Killer Queen’s psychological influence. On I-Island, rapid fingernail growth warns him that Hamon is becoming less able to suppress it 363.

Sheer Heart Attack

Sheer Heart Attack is Killer Queen’s Second Bomb, normally housed as a skull on Jilan’s watch. Activating it produces a small tank with a speaking skull and a distinct personality 297 373.

• Jilan switches forms by touching the skull twice with Killer Queen 373.
• Cognition chips give deployed units a radar-like monitoring function 411.
• During the forest attack, he uses the tanks against Muscular and the magician, then sends Sheer Heart Attack toward another enemy within the mist 411 412.

Perception, Disguise, and Tactics

Jilan combines close observation with deception, environmental traps, and practical planning.

• Observation: Detects surveillance efforts that Ueno considers impossible to conceal from him 73.
• Disguise: Channels Hamon into his cheeks to alter his facial shape while impersonating Robin Hood 305.
• Environmental sensing: Uses Hamon to locate Ragdoll’s position and notices disturbances associated with Kurogiri’s appearance 411 412.
• Improvised traps: Creates a smoke-filled room and stages a dust explosion to mislead Shadow’s men 305.
• Infiltration planning: Equips Kaminari with a guard’s clothing and tranquilizer gun, then routes the I-Island group through Melissa’s equipment storage 345.
• Combat limitations: Acknowledges that Bakugo’s close-combat awareness exceeds his own, while Isana’s strength and Quirk type make him an opponent Jilan cannot handle directly at that point 140 264.

Languages and Performance

• Translation: Uses languages learned in his previous life to earn money through online work 62.
• Singing: Impresses Soul’s members and audience with “Radio Ga Ga,” but declines an invitation to become the band’s lead singer 154.
• Stage planning: Offers to advise Soul’s presentation and helps organize the zoo’s circus publicity 154 191.
• Acting: Briefly portrays King Solomon at the Tottori Sand Dunes festival 389.

Equipment & Items

• Firefighting combat suit — Chosen for rescue work 34.
• Skull-faced watch — Houses Sheer Heart Attack when inactive 373.
• Raw Stone — Blue material linked to the Stock Solution’s energy; its disappearance inside the tank precedes Sheer Heart Attack’s evolution 372 373 386.
• Cognition chips — Installed in tank units for testing and perimeter surveillance 411.
• Second phone — Used for special clients and location tracking; thrown through Kurogiri’s gate to verify its destination 191.
• Silicone hands — Collected from life-sized dolls purchased with his earnings. The hands in his bedroom are artificial, not human remains 13.

Relationships

• All Might — Inspiration and mentor figure. Praises Jilan’s actions during the U.A. attack and comforts him after the Sports Festival, presenting his silver medal and embracing him as he cries 13 52 142.
• Izuku Midoriya — Classmate whom Jilan advises about injury and Quirk use. After deducing that Midoriya is All Might’s successor, he hopes Midoriya will become their strongest asset against All For One 133 371 402.
• Katsuki Bakugo — Competitive classmate frustrated by Jilan’s reluctance to fight seriously. Jilan later accepts a challenge because he considers their internal conflict dangerous in the face of DIO’s threat 20 225.
• Momo Yaoyorozu — Frequent teammate. They cooperate in the Sports Festival race and the forest crisis; Jilan treats her after Toga’s attack 108 407 420.
• Toru Hagakure — Training partner and classmate. Their coordinated plan defeats Todoroki and Shoji, and she later anxiously checks on his recovery from I-Island 25 390.
• Ibara Shiozaki — Long-standing acquaintance first connected to his junior-high years. Accompanies him aboard the Voyager and assists in restraining captives 60 62 305 322.
• Tenya Iida — Respects Jilan as a capable class representative and shares his ambitions concerning Midoriya with him 110.
• Fran Grimm / Little Red Riding Hood — Artificial human who comes to regard him as her father. Jilan accepts the role emotionally, earns Senzaemon’s approval, and takes her traveling 340 377 379.
• Erina Nakiri — Initially an adversary who vows to defeat him through the Totsuki Group; later shares responsibility for Fran. Jilan describes their connection as one of common interests rather than an established romance 73 371 379.
• Mad Rabbit and Aoi Hana — Work-study director and fellow zookeeper. Jilan helps with animal care and circus arrangements, then returns to consult the director about Isana and Raw Stone 175 191 384 386.
• Diduo Chengjie and Kyoka Makoto — Musical associates. Diduo questions why Jilan vouched for him after his arrest, while Kyoka invites Jilan to front Soul 57 154.
• Shota Aizawa — Teacher who struggles to devise specialized training for Hamon because of its versatility and Jilan’s existing continuous use 400.
• Tomura Shigaraki and Kurogiri — Enemies who repeatedly try to recruit him. Shigaraki’s Decay is ineffective against Hamon, while Kurogiri attempts to exploit Jilan’s reputation and concern for classmates 190 236 414.
• DIO / All For One — League leader whose interest in Jilan becomes a major source of fear. Jilan seeks to limit further contact rather than meet him directly 219 236 371.

Story Role / Major Arcs

Hero Training and the U.A. Attack

Jilan first appears as a remarkably calm hostage during a bank-robbery confrontation interrupted by All Might. The robbers involved him after attempting to take his hard-earned wages 1 5.

At U.A., he becomes Class 1-A’s representative. During combat training, he heals Hagakure, predicts Todoroki’s solo approach, and launches a costly ambush while Hagakure captures Shoji’s hand before he can reach the objective. Their villain team wins 20 25 323.

During the villain attack, Jilan uses a stolen walkie-talkie to contact other zones and shields classmates from Nomu’s assault. The incident also brings his encounter with Yoshikage Kira and the emergence of Sheer Heart Attack. His subsequent police report helps the investigation into the League of Villains 41 48 49 52.

Sports Festival

Jilan and Yaoyorozu cross a difficult race obstacle using a pulley, mountaineering equipment, and Hamon. Later, he defeats Shinso by identifying his verbal activation condition and feigning brainwashing 108 122.

He defeats Todoroki while experiencing an unnaturally cold, accelerated analytical state. Afraid of its effect on his emotions, he contains it with Hamon, but his destructive urges intensify. In the final against Bakugo, he struggles to restrain himself and accidentally turns Bakugo into a bomb. He finishes as runner-up and breaks down when All Might comforts him 140 142.

Zoo Internship and League Recruitment

Jilan spends a week working at Mad Rabbit’s zoo, caring for its unusual animals and helping arrange a circus. During this period, Kurogiri tries to draw him into the Hosu battle in a way that would damage his standing with heroes. Jilan recognizes the trap and avoids public intervention 175 190 191.

The League continues treating him as a potential recruit. When Shigaraki confronts him, Jilan overwhelms him with Hamon before Kurogiri intervenes. He refuses their invitation but remains troubled by their certainty that he belongs with them 235 236.

Voyager and Little Red Riding Hood

Aboard the Voyager, Jilan encounters Isana and becomes involved in the struggle surrounding an enormous sperm whale. He uses Sheer Heart Attack while allowing others to mistake it for advanced support equipment 264 275 291.

After examining Little Red Riding Hood, he discovers extensive chemical damage and ambergris traces in her body. He impersonates Robin Hood, traps Shadow’s men, destroys Toga’s clone with Killer Queen, and abducts Twice. He later reunites with his friends after surviving the shipwreck and reaches I-Island 305 322.

I-Island Crisis

During the island’s lockdown, Jilan helps organize the students’ infiltration and their attempt to reach the security controls. In the final battle, he drinks all of Dr. David’s Stock Solution, using amplified Hamon and electromagnetic control to confront the enemy and help rescue All Might 345 364 365.

The drug’s aftereffects leave him unconscious for two days. After recovering, he requests a meeting with Dr. David before departing. On the return flight, he discovers Sheer Heart Attack’s evolved form and pieces together Midoriya’s connection to All Might 367 371 373.

Becoming Fran’s Father

Little Red Riding Hood receives the name Fran Grimm and forms a family-like bond with Jilan and Erina. Jilan’s initial uncertainty gives way to genuine attachment 339 340 372 377.

After passing Senzaemon Nakiri’s test, he receives recognition as Fran’s father and permission to take her traveling. Their trip brings them back into contact with the zoo group at the Tottori Sand Dunes, where Jilan asks the director about Isana and the energy source behind the animals’ transformations 377 382 384 386.

Forest Training Camp

Jilan investigates the poisonous purple mist, revives Ibara, and sends classmates to warn the others. His prearranged tank defenses intervene against Muscular, while he pursues and incapacitates the magician who compressed Ragdoll 407 411 412.

The League uses Jiro and Hagakure as hostages, forcing negotiations. Jilan refuses another recruitment offer and survives an attempted forced capture, though a Nomu wounds his shoulder 413 414 415 417.

After the villains retreat, he reveals that they received a fake marble: Ragdoll remains in the real one. He cancels Compress with Hamon and returns her to Mandalay 420.
