Description
Kayo Senju is a ten-year-old girl who serves as an Initiator, a young individual infused with the Gastrea virus to gain superhuman abilities in exchange for the risk of eventually transforming into the monster themselves. Her designated promoter, or partner, is Shougen Ikuma. Kayo has a small physique, light blue hair typically worn loose with a fringe covering part of her forehead, and distinct crimson eyes. She is recognized as a Dolphin Model Initiator, a classification that emphasizes intellectual capability over raw frontline combat power, possessing an extremely high IQ of 210.
Personality-wise, Kayo is characterized by her silent and obedient nature, seldom questioning the orders of her promoter Shougen, even though he openly regards Initiators as little more than disposable tools for combat. Despite this, she takes her role as an Initiator very seriously and demonstrates considerable courage and skill in battle, confronting Gastrea without fear. Beneath her reserved and pragmatic exterior lies a kind and insightful individual who exhibits a clear desire for genuine human connection and understanding.
In the story, Kayo is part of a team assembled by the ruler Seitenshi to undertake a critical and dangerous mission. Her character becomes central when she becomes separated from her promoter and is discovered alone and injured by the main protagonist, Rentaro Satomi, and his Initiator, Enju Aihara. Rentaro treats her wounds and engages her in conversation, during which Kayo reveals the harsh realities of her life, admitting that she has killed before under orders. Rentaro's response--insisting that Initiators are human beings and family, not tools--profoundly affects Kayo, as he is the first person to treat her with this level of care and humanity.
The nature of her relationship with her promoter, Shougen Ikuma, is utilitarian and cold; he sees her as a means to an end. In contrast, her brief but impactful relationship with Rentaro Satomi highlights her desire to be valued as a person. Her interactions with Enju Aihara are initially tinged with professional rivalry, though circumstances force a fragile cooperation between them. Kayo's development culminates in a final act of self-determination. While fighting fiercely to hold back Gastrea and protect Rentaro's position, her contamination level rises beyond the critical fifty percent threshold, her body beginning to transform into the very monsters she fights. Accepting her fate, she requests that Rentaro kill her while she still retains her human consciousness and identity. Rentaro, honoring her wish, fatally shoots her to prevent her transformation, marking a tragic end to her story.
As an Initiator, Kayo possesses a range of notable abilities derived from the Gastrea virus within her. She has a supremely enhanced physique, granting her incredible agility and speed, as demonstrated when she can quickly retrieve her promoter's sword mid-flight and kick it back to him with precision. She also has superhuman recovery speed, able to heal from injuries faster than a normal human. Her defining strength, however, is her cogitation or high intelligence, which she uses strategically in battle to outthink and eliminate enemies, compensating for the Dolphin model's lower direct combat power compared to other Initiator types.
