Toge is a slim young man with light skin, greyish-purple eyes, and mid-length straight hair. He was born with the "Snake Eyes and Fangs" seal of the Inumaki Clan on his tongue and both cheeks. His Jujutsu High uniform was tailored with this in mind, fitted with a high collar with a zipper that covers his mouth. While training, Toge wears a zipped-up dark collared shirt underneath a white short sleeve shirt with athletic pants and shoes Toge's initial impression leads people to believe he's a quiet, aloof, and distant person, however, Toge is actually a highly insightful and caring individual. He is intelligent and understands the dangers of overwhelming power. Toge chooses not to speak in a conventional manner in order to protect people from his Cursed Speech. Speaking in rice ball ingredients makes it difficult to understand him, but many of his friends have taken the time to learn how to communicate with him. Toge possesses the "Snake Eyes and Fangs" seal of the Inumaki Clan on his tongue and around both sides of his mouth. This allows Toge to infuse his words with cursed energy to improve the spirit of his commands, forcing all who hear it to obey. This power can target living beings and inorganic objects. The more demanding the command, the more of a toll it pays on Toge's body. Weaker curses can be exorcised with powerful commands without backlash, but even less powerful words will consume more energy and stamina when used against opponents with more cursed energy than Toge. Communication devices and voice amplifiers, such as cellphones and bullhorns, do not disrupt Toge's technique, allowing him to project his words and their effects over a longer distance if need be. Toge's safe words Salmon — Used for affirmation. Fish Flakes — Used for negation, and usually negative. Kelp — Used as a greeting. Mustard leaf — Used to show concern/worry, "I'm on it". Salmon Roe — "Well, well" or "My, my". Caviar— Used as an expletive/curse word. Spicy Cod Roe — Used motivationally. Tuna, Tuna Tuna — Used to call attention to something, "look". Tuna Mayo— Used as general talk, "do something" (about the situation). Everything else is gibberish.
