Kayama Shuuji

A first-year high school student who joins the camp as an assistant. He is a good-natured person who is kind, gentle, and heavily relied upon by others. But after getting lost in another world where his general knowledge no longer applies, enthusiasm alone precedes his ability to take action, revealing a weak side in which he places the blame on others and his surroundings.

He sees his digimon partner, Lopmon, as lazy and neglects it.
