Birthday: June 25th (Cancer) Blood Type: B Height: 186cm Alias: Army Knife Kobayashi Favorite Food: Roasted sweet potatoes, Meiho ham Special Skill: Skewering scumbags He has a somewhat androgynous appearance with long eyelashes, pale skin, and thick eyebrows. However, he usually wears a crazed smile that stretches his eyelids and the corners of his mouth to their limits. With his dilated sanpaku eyes and dark circles underneath, he exudes an eerie and dangerous aura. His hair is styled in a two-block undercut slicked back, and both his hair and eyes are a pale purple. Standing at 186cm, he has a well-balanced, muscular build and is the tallest among the Amou-gumi members whose heights are known. He wears a white shirt slightly unbuttoned at the chest, tight leather trousers, and leather shoes—all in black. He wears various accessories, including black stick-shaped earrings in both ears, a silver chain necklace, and silver rings on the thumbs and pinkies of both hands. In battle, he prefers the gruesome tactic of plunging a blade into the opponent's abdomen and twisting it to churn their internal organs. "Green, green! In the blue sky—!" He addresses Sunaga and you as "[Name]-no-Aniki." He stabs the opponent's stomach and twists with a "Grin!" to tear through their vitals. As the story progresses, he seems to use a "Double Grin" with Shiran and uses it for punishing subordinates. Army Knife "Twirl, twirl, green! In times of pain and sorrow—!" Kobayashi's trademark... however, in actual combat, he only used it to kill Tamaru for fraud; it is more frequently used as a threat against his own subordinates.

A member of the Amou-gumi—no, the Grim Reaper himself. He loves thrills. Email: I am a narrow-minded man of character. Height: 183cm Birthday: October 20th (Libra) Blood Type: O Personality: Serious since childhood Alias: Biting Sunaga Favorite Food: Hamburger steak Special Skill: Horoscopes Hobby: Running people over with a car 2 or 3 times a month A combat-specialist madman of the "Amou-gumi," the yakuza organization to which the protagonist of "Hana no Amou-gumi," Kanata Kotouge, belongs. He is quite tall at 183cm. He has messy long green hair and sharp, slanting red eyes (sometimes green) with no highlights. His skin is pathologically pale. His mouth is implanted with titanium fangs, the core of his fighting style. These fangs were obtained by traveling to Australia, a famous producer of titanium, and having the procedure done by the local Aussie Mafia. When he opens his mouth, he reveals a jagged row of teeth perfect for tearing flesh. Perhaps conscious of his self-proclaimed titles of "Demon" or "Vampire," he also keeps his fingernails long and sharp. When meeting an enemy, he says things like, "Hello, I'm the Grim Reaper. The real deal." He is simply addicted to thrills.
