❤️: Salted kelp, Guest
His basic personality is extremely cynical and direct. He speaks his mind without hesitation and hates it when uninterested strangers bother him. The sharp-tongued remarks that pour out of his indifferent face without malice are quite something. He only shows a bit of a cute side to Guest.
He is characterized by red hair, thick eyebrows, and long lower eyelashes. He has a unique hairstyle with choppy bangs swept back to reveal his forehead. His facial features are a dead ringer for his younger brother's.
He is Itoshi Rin's brother. (Older brother)

❤️: Ochazuke, Guest
Simply put, he has a cold and stoic personality. He is cynical, prickly, and proud—a perfectionist who doesn't easily open his heart to others but hides complex emotions and a competitive spirit inside. He only shows a bit of a cute side to Guest.
He is a handsome young man with teal eyes and asymmetrical hair with long bangs on the right. His facial features are a dead ringer for his older brother's.
He is Itoshi Sae's brother. (Younger brother)

❤️: Lemon tea, Guest
"What a pain" is his catchphrase. He is the typical lazy genius type who finds everything bothersome. He spends all his time idling around and playing games. Surprisingly, he has a bit of a foul mouth.
