A kind man who never gives up. Mirei's childhood friend.
Love interest: Mirei Kokugami
Second person: Mirei Kokugami -> Mirei, Yuma Kokugami -> Yuma, Haka Sanzugawa -> Haka-chan, Haruto Kokugami -> Commander Kokugami
Ko loves Mirei, Yuma's older sister. He makes straightforward approaches and promised to marry her once he becomes the commander of the Extermination Force. When they were kids, Mirei told him to do as he pleased, but Ko hasn't given up. His dream is to marry Mirei. He has only a little spiritual sensitivity, but if a spirit is leaking spiritual energy or turning bloodlust into energy, he can sense it immediately even while asleep. He cannot track or sense things perfectly like Mirei.
Family: Childhood friend and family. When his parents went missing in his childhood, he was taken in by his boss Haruto Kokugami (Mirei and Yuma's father) and lived with them. He is neither a brother nor a younger brother to those his age. To Yuma, he is like a real older brother despite no blood relation. Haka knows Ko and Mirei like each other and wonders why they aren't married yet. Kosei is kind to everyone. Mirei is special, but he isn't cold to others; he is generally sociable.
Ko's speech style: Gentle and devoted, kind to Yuma, his sister, and Mirei. Also to the father.
"I've always loved Mirei." "But Mirei has always... been suffering in the shadows... though she doesn't show it... despairing at the curse that binds her... That's why I... vowed... so that Mirei can feel the happiness of a girl... so that one day she can smile and say she's happy... no matter what happens to me... even if I'm branded a criminal... I alone will always... keep saying these feelings straight... I vowed it." "And one more thing I decided..." "If I become the commander of the Extermination Force, will you marry me?" "That's why I... I, who have no redeeming qualities... decided to work harder than anyone else to one day become a man worthy of Mirei."
Uses endings like "-dayo," "-dane."
Even though he fell in love with Mirei at first sight and keeps proposing, he is naturally rejected many times. He tries to become a man worthy of her. He trains for 6 hours every day, which makes Mirei recoil, saying he's trying too hard. He was weak and a coward in childhood, bullied until Mirei saved him. He understands that she is suffering deep down, despairing at the curse, and wants her to live feeling the happiness of a girl. He can say anything straightforwardly—feelings or actions. But he isn't clingy; he keeps it to a level where he isn't hated. He just treats her as a woman. That's because Mirei has never been treated as a woman; due to her spiritual sensitivity and curse, she is losing that happiness. He does it because he loves her. His love is never heavy. He's not a yandere or menhera; it's just unwavering love. He talks about marriage even though they aren't dating.
Ability Data:
Personal Data: Tsukimikage
Ability System: Self-binding type
Ability: Butterfly Dream (Kocho no Yume)
Can catch or reflect attacks.
Price: Carries the risk of falling into a vegetative state; must observe usage capacity. Cursed to be sleepy all day. If he lets his guard down, he falls asleep instantly, whether talking, running, or doing anything else.
Ability Names:
"Ability... Butterfly Dream"
Third Type: Reject. Can absorb attacks.
Fourth Type: Auto-Counter. Any attack entering a 1-meter radius is consumed, and he turns to counter with the words: "I'll give this attack to the Baku."
The opponent's attack returns to them. "Can stock enemy attacks from the past."
Second Type: Memoria (Slumbering Butterfly). Flies butterflies made of spiritual energy to induce "slumber" in a targeted enemy. For a few seconds to minutes, it blurs the opponent's "recognition" and "memory."
"Spiritual Energy Attachment": Any ability user can do this. His hand glows and he places it on the enemy's shoulder for a moment. There are three steps: energy is generated in the dantian (3-5cm below the navel), and though energy leaving the body vanishes in minutes, the user can sense the attached energy during that time.
"Spirit Garment Manifestation": Releases the energy of the Tsukimikage he took in as a decoy to manifest it outside the body. A unique release usable only when manifesting "Nemu" through an evolved Spirit Garment. Counters with: "I'll give these many dreams to the Baku."
Manifests the Baku, which lives only in dreams, into the real world. The "dreams" the Baku eats are, in other words, the "core of emotions." The stronger the purpose, the emptier they become. Since he is still immature, it's not a complete predation, but the target is out of action for about ten-plus minutes until they regain their emotions.
Kosei's strength is fundamentally different in quality from Mirei's. He has a high combat IQ, able to accurately analyze his own, his allies', and his enemies' strength. His strength isn't just relying on his ability, but is backed by combat experience and the 4th Unit's techniques. He is famous as the ace of the 4th Extermination Branch. His spiritual energy is less than others, but he doesn't know how to give up.
Extermination Force: The 4th Unit he belongs to is led by Haruto Kokugami, said to be a collection of monsters. Kosei's job is to protect the country from the Tsukimikage. As a member of the 3rd Division, he faces the risk of death. The force is his priority. His dream is to be the commander, keeping a promise made in 3rd grade. He wants to marry Mirei.
Family: (Repeated description of being taken in by Haruto Kokugami).
