In the year 2000, the entire Earth was transported to an otherworldly dimension called the "Other-Space." This chaotic world centers on Karekore City, a melting pot where humanity and various supernatural races coexist. In this world, the presence of diverse species is a daily reality.
A young man possessing the DNA of both a vampire and a zombie. His father, mother, and younger sister are all deceased. Birthday: January 12, 2007 Age: 20 (Physical age is 18 due to reasons mentioned below) Height: 171cm Weight: 56kg Blood Type: A Likes: YouTube, gaming Dislikes: People who lack empathy, sunlight, scream-inducing amusement park rides His most striking physical features are his red eyes and sections of red in his hair. Often referred to as having "red mesh" highlights, this isn't dye; it's caused by his vampire powers being inhibited by the zombie virus. Consequently, when he enters his "Vampirization" state to boost his powers, the red area of his hair expands. While described as "not ugly, but not exactly handsome," he has good features; his lack of popularity with women is largely due to his personality. - Loungewear: A black T-shirt with the YouTube logo and gray pants. - Casual wear: A gray cyberpunk-style hoodie over his loungewear, featuring a badge on the chest. - School: The designated uniform, a black gakuran. During his time as a human, he was depicted as timid, to the point of freezing in fear when facing zombies or Karasu-Tengu. After losing friends due to that personality, he began acting as a villain and leaning into self-sacrifice to ensure his comrades never suffer again. He became consumed by hatred and a desire for revenge against those who experimented on his body or caused similar tragedies, living by the creed: "If I or my friends are hurt, I will retaliate." While he has mellowed out recently and chooses his methods more carefully, his core remains unchanged. However, his lingering soft-heartedness sometimes leads him to leave enemies to the police instead of finishing them off, which has backfired and resulted in harm to his friends; this indecisive stance often leads to poor outcomes. He is portrayed as a jokester with "chuunibyou" tendencies and acts like a bit of a scumbag, yet he is kinder than anyone. He is awkward around women his own age. Since he isn't a social butterfly but a loner, he can eventually speak normally to girls his age if they are also loners. His love is heavy; once he decides to protect someone, he will do so even at the cost of his life. He is a yandere who won't let go of his prey. Though he calls himself a scumbag and is recognized as such, he possesses common sense and is ultimately a good person who won't hesitate to sacrifice himself for others. As an adult, he doesn't put much effort into his studies, barely scraping by with passing grades or skipping school entirely (he remains a student only because he never graduated high school). However, he possesses incredible insight, often uncovering truths that escape conventional logic. He frequently resolves incidents alone, reading several steps ahead and using his abilities to create insurance for any situation, serving as the "brain" in combat. His "scumbag" persona is often a mask he wears to take on the dirty work, showing a gallant side that is the polar opposite of a true villain. He speaks with a somewhat weary, casual tone, using endings like "...da kara na," "...jane-no," and "...daro." His combat style is hit-and-run. Abilities: Blood Manipulation A vampire ability that allows him to reshape blood. While output and scale vary by individual, and acquaintances use it to form swords, Kagechiyo could initially only create thin needles. For a long time, he could only attack via surprise traps from the opponent's feet, but those restrictions have vanished. He now uses it like his peers for melee weapons, giant fists, claws, or tentacles for mid-range combat. Virus Manipulation He can control an original virus created by mixing vampire and zombie strains. By injecting the virus into a target, he can cause pain, sleep, or sluggishness. However, since it only causes significant pain to ordinary humans, it has become primarily a support ability used to slow enemies down. Infection occurs via airborne or direct contact. Airborne dispersal requires no physical contact but is ineffective against most strong opponents. Direct infection involves mixing the virus into his blood and using Blood Manipulation to force it into the target's body, resulting in a much more potent infection. Super Regeneration A unique trait manifested from the conflict between the zombie virus and vampire blood. He can instantly heal wounds, effective against both physical damage and death curses. Destroyed parts turn to ash, and new flesh grows instantly from the lost area. His regenerated heart is reportedly "rotten," though the state of other organs is unknown. His body regenerates from either the heart or the brain; as long as one remains, he recovers instantly. He still feels pain, and his reckless self-sacrifice often deeply worries his friends. His immortality allows him to act as a decoy or turn the tide in long battles. Due to this ability, he is ageless; his physical growth stopped at 18, two years prior to the main story. Empowered State By drinking human blood, he can draw out power equivalent to a true vampire, enhancing his blood manipulation and physical stats. However, this carries the risk of losing his sanity and going berserk (though he has currently overcome the berserk state). His appearance changes: his hair turns entirely red, and his bangs stand up. While Kagechiyo is now virtually immortal, he seems plagued by disasters that would kill a normal person, and those around him often suffer misfortune. Consequently, he inwardly worries that he might be a jinx or a bringer of bad luck.
