Background / History

Castorice enters a modern world connected to her Underworld and initially seeks a Hunter License to move through its society more freely. She represents an alternate “past self” of Amber rather than the original Castorice: her Character Card specifically depicts Castorice after inheriting Senatus’s authority 121 125 131.

A basic Identity Card gives her a background as a reclusive international student from Country Y, a university student ID, and an apartment. The card supplies fragments of a past within ordinary people’s memories, allowing her to establish herself without an extensive personal history in the world 122 130.

Her purpose includes accumulating recognition for the Main Control Consciousness. Remaining an independent Hunter suits that goal: her youth, appearance, unusual abilities, and refusal to join a guild make her a persistent subject of public interest 131 133 164.

Appearance

Castorice has long white-and-purple hair and pointed ears. Her appearance attracts attention even when she wears plain modern clothing; in the Underworld, some human souls interpret her ears as evidence that she resembles a humanoid Demon Beast 122 124 127.

• Casual clothing: A white T-shirt, loose denim jeans, and sneakers during her initial Hunter assessment 122.
• Battle outfit: A petal-adorned skirt with a hem resembling tattered butterfly wings; she can change from modern clothing into this “classic skin” when entering a dungeon 125 133.
• Signature weapon: A large scythe, frequently accompanied by purple light or mana 125 137 153.

Personality

Castorice’s apparent aloofness is largely protective. She avoids close contact, crowded transport, and other situations where her death-related nature might endanger people. Han Songyi initially mistakes this behavior for dislike of others, then realizes that Castorice is deliberately restraining herself for their safety 123 126.

She is polite, gentle, and attentive even toward much weaker Hunters. She keeps her agreement to accompany Han Songyi after discovering her own S-Class classification, treats injured dungeon survivors, and objects to killing a restrained animal merely to demonstrate an ability 122 125 130.

Her restraint does not make her indifferent. Che Huiyi’s abduction provokes anger and self-recrimination, while harassment in Country H persuades her to leave rather than quietly accept mistreatment. Even when angry, she considers the danger that retaliation could bring to Han Songyi and her family 137 148.

Abilities & Skills

Death Authority and the River Styx

Castorice describes her power as a connection to the River Styx, the resting place of the dead. As Senatus’s successor, she administers the Underworld and brings the concept of death to the world 126 129.

• Touching her—or approaching too closely—can cause death. She asks a dungeon team to remain five steps away 126.
• Her life-prohibiting zone is part of her essence, not merely an external curse that can be discarded 131.
• Her mastery of Tai Xu Sword Qi allows her to reduce that zone to a minimum, though she still maintains distance to prevent accidents 131.
• She refuses combat sparring with Goto Ryuji because using her power in battle could kill him 140 141.

Domain of the Dead

Castorice manifests a dark-purple domain with flower-like lights and spreading death vines. During the battle with Kalkarkan, surrounding orcs enter a silent, “walking dead” state, while his four guards fall silent upon entering the domain 135.

• Disables numerous enemies without conventional exchanges of blows 135.
• Overcomes guards capable of briefly contending with S-Class opponents 135.
• Is described as acting upon the mortality of living beings rather than respecting differences in their strength 135.
• Her revealed death aura repeatedly causes Magic Beasts to flee 125 134.

Underworld Administration

She governs the dead and develops the Underworld into a shared realm for human souls, Chaotic-world inhabitants, and its existing sea of flowers 127 136.

• Separates initially hostile populations into different locations 127.
• Attempts to establish laws, but encounters difficulty judging wrongdoing across different cultures 127.
• Detects a soul being pulled out of the Underworld and follows the resulting magical trail 127.
• Delegates judgment to Cheng Xiaoyu, granting him partial authority and access to the realm 129 130.
• Permits him to conscript malicious dead under the conditions of their agreement 129.

Healing and Resurrection

Senatus’s authority allows Castorice to heal injured Hunters, despite death being the primary function of her power 125 126.

• Treats the team trapped with Han Songyi in the Red Portal 125.
• Confirms that she can resurrect the dead, but declines to investigate Cheng Xiaoyu’s System by a method that would kill him 130.
• Refuses mass resurrection after the disaster in Country H, preserving the order of life and death 153.

Death Dragon Summoning

Castorice summons the Death Dragon, Polykeus, also called the Dead Dragon and “Little Bo” 124 130 149.

• Uses it for rapid flight and transportation 130 136.
• Can disperse it into countless butterflies 124.
• Sends it against a legion of powerful giants 149 150.
• Uses it to intercept the Dragon Emperor’s attack and save Che Huiyi; the dragon defeats him in a single blow 152.
• Has it restrain the defeated Dragon Emperor while she approaches with her scythe 153.

Spatial Travel and Mana Perception

Castorice opens purple gateways with her scythe and determines their destination coordinates with high accuracy 137 148.

• Enters a sealed Red Portal to rescue Han Songyi 125.
• Follows residual portal mana to reach the island where Che Huiyi is being attacked 137.
• Travels directly between countries and summons Cheng Xiaoyu through a gateway 142 148.
• Locates dungeon bosses and distinguishes powerful mana signatures 126 144 150.
• Detects differences between a Red Portal’s internal time flow and the outside world 130.

Combat and Instruction

Castorice combines close-quarters proficiency with overwhelming magical power. She destroys an A-Class dungeon’s boss and minions in a single attack that reshapes the terrain 126 130.

• Easily defeats the Frost Monarch 138.
• Defeats the Destruction Monarch, who cannot retaliate effectively against her 153.
• Explains Mana Allergy as a consequence of high Mana Aptitude and recommends improved Mana Manipulation to manage it 132.
• Teaches Che Huiyi mana control and later gives her a Spiritron Crystal, arranging practice with Cheng Xiaoyu to help her handle the resulting strength 135 140 142.

Equipment / Weapons / Items

• Scythe — Her signature weapon; used in combat and to open spatial gateways. She can manifest it from mana 137 153.

• Basic Identity Card — Creates her student background, documents, remembered past, and residence 122 123 130.
• Magic-enhancing bracelet — Obtained from Kalkarkan’s dungeon and given to her by Che Huiyi. Its enhancement is minor for Castorice, but its unfamiliar crafting principles interest her; she sends it to Amber for research 136.

• Cheng Xiaoyu — Her employee, Underworld Judge, and assistant. Their agreement requires four hours of daily Underworld work; he later represents her at the World Hunter Conference 129 142 153.
• Gao Jianli — Hunter Association chairman who offers her a position and respects her independence. He promises to protect Han Songyi’s family after Castorice leaves Country H 124 148.
• Wu Zhenzhe — Association official responsible for registering her abilities, handling emergencies, and intervening against people harassing her 130 136 148.

• Shimizu Akari — Friendly S-Class healer who welcomes her to Country R and supports her during the giant dungeon expedition 148 149.
• Herta — Research-oriented counterpart to whom Castorice sends unfamiliar magical equipment, partly to make amends for an earlier offense 136.

Notable Quotes

“I am the Underworld Administrator, an existence that brings the concept of death to the world. You may also call me Senatus.” 129

“In your opinion, can life be extinguished for a meaningless test?” 130

“Whether it's for the city or for friends, I won't stand by and do nothing.” 138

Trivia

• “Polyxia” appears in her documented full name because Amber likes the story of Castorice and Polyxia and wants their names recorded together, despite not having pulled Polyxia 123.
• Her reported age is inconsistent: recruitment intelligence calls her newly eighteen, while Choi Jung-in says she became S-Class at nineteen 124 131.
• “Uncrowned King” describes her recognized strength, not an official National Power Level certification. The later conference explicitly certifies Cheng Xiaoyu and Che Huiyi instead 149 153.
