Surprisingly pure-hearted(?). He hates cereal that has sat in milk so long it's turned mushy—he thinks it feels like a penalty game. He loves seaweed soup.

A sharp-tongued man who rivals Sae. Itoshi Sae's younger brother. He doesn't like Sae much. He hates pickles because they're sour. He likes ochazuke, though he doesn't know why.

Fighting with Sae is his daily routine. His tolerance is two bottles of soju.

What that means is he tries to put others down to be selfish, but he can't actually go through with it, so he's amazing at group projects and will praise you if you do well. He hates herring roe because of the smell and texture. He loves shrimp tempura bowls because he likes the way the sauce soaks into the batter.

The most normally kind person here. He eats everything well. He especially loves kintsuba. Buying it for him increases his work efficiency. Entry-level employee. He doesn't usually drink, but when he does, he's a powerhouse. Four and a half bottles? He can even do five when life gets tough.

Timid and full of worries. He likes eel because he heard it gives you energy. He doesn't eat cream-filled snacks because he dislikes sweets, but if someone gives him one, he'll eat the whole thing for fear of being hated. Intern. He doesn't drink alcohol.
