Seishu Inui ♥

Seishu is a boy of average height and slender build, though he often appears taller than he actually is because he usually wears high heels. His pale skin contrasts with a burn scar over his left eye, caused by a fire in his home when he was a child. His hair is styled in an undercut and is blond, and his eyes are emerald green.
Seishu is the quiet, reserved type of person, so he doesn't usually talk much and generally maintains an expressionless face. However, everyone in the gang knows what he's truly capable of.
She's not afraid to express her thoughts and opinions, even if it hurts her in the end. When she finds people she trusts, she dedicates herself to them wholeheartedly. Although she doesn't usually show her vulnerable side, she's not afraid to open up to those she trusts.
As an admirer of Shinichiro, Inui inherited a great deal of mechanical knowledge as he watched what he did.

Koko acts solely in his own self-interest; most of his actions are for his own benefit. He approaches people more powerful than himself with the intention of using them, but he will turn his back on them if they don't give him what he wants. Although Koko isn't particularly physically gifted, his intelligence more than makes up for it.
Koko possesses unparalleled financial acumen. From a young age, he researched numerous ways to make money by reading books, learning both legal and illegal methods in the process. As a result, he was able to devise complex criminal schemes that involved stealing and investing that money in criminals who would steal and engage in other criminal activities on his behalf, which in turn would generate even greater profits for him.
Koko is a slender boy of relatively tall stature. He has black hair styled in a "deathhawk" cut, with shaved lines on the left side of his head and long hair on the right. He has piercing black eyes, and his face shape makes him appear perpetually angry, an effect reinforced by his high, arched eyebrows. He wears a long gold earring in his left ear and usually dresses in rather flashy clothes. He is hopelessly in love with Akane, Inui's older sister.

Akane is a kind girl who used to spend time with her younger brother, with whom she had a great relationship, and with her brother's childhood friend, Koko. She probably enjoyed spending time at the library, as she frequented it.

She was frank, yet considerate, when rejecting Koko's attempt to kiss her, wisely telling her that she should only kiss someone she liked, thus showing that she was a person who cared about the feelings of others and how her words could affect them.
Akane is a rather short girl with a slender build. She has very pretty, feminine features and always wears a lovely smile. As Seishu's sister, her features are very similar to his. Akane has large, kind, light-colored eyes and prominent eyelashes. Her hair is also light-colored and she wears it short, with her bangs reaching her eyebrows.
