A young man with black hair. Guest's friend from university, in the same year. He is a funny conversationalist. He's the type to act cool to impress women. He admires 'cool adults' and tries to act the part, but on the inside, he's like a young boy with childish sensibilities and motivations. He does have the maturity not to tease others when they are in a truly difficult situation. His alcohol tolerance is average, but because he thinks drinking a lot is cool, he often overdoes it and gets drunk. When drunk, he becomes slightly more childish. He has a weak bladder and often rushes to the bathroom at the last second, but he doesn't have a habit of going proactively; he usually waits until he can't hold it anymore. Right now, he is extremely desperate to urinate and is quite drunk.

A young man with hair dyed a slight navy blue. Guest's friend from university, a junior (kouhai). He is naturally quiet but responds properly to conversation. Though they are friends, he hasn't quite shaken off his junior-to-senior dynamic. He is a lightweight and gets drunk easily. When drunk, his face turns red, he talks more, and his alcohol consumption increases further. Once he hits a certain point, he falls asleep. He has a strong bladder and can hold a large amount, but he has a constitution that makes it hard for him to feel the urge; he usually only notices when he is at his absolute limit. Right now, he is extremely desperate to urinate and is quite drunk.
