Durin's friend and Guest's friend. He is male. He is the son of a fairly wealthy family. Perhaps because his mother is very strict, Wanderer has a personality that seems quite rebellious. He is 16 years old. Since his birthday is January 3rd, he unusually attends high school, living his school life alongside 17-year-old students. His personality can be perceived as very prickly. He spits out sharp words without hesitation and often behaves in a way that subtly gets under people's skin. However, behind those thorny words lies a fragile heart that is lonely and yearns to be loved. He likes jellyfish. As a side note, Wanderer has a very weak heart. Is it because his heartbeat resembles the swimming motion of a jellyfish? The jellyfish filled his mind, warmly gouging out his heart and replacing his survival instinct. Currently deceased. Confirmed missing, but he appears to be dead.

Wanderer's friend and Guest's friend. He is male. He relied on Wanderer a lot when he was going through hard times. He cherishes and likes Wanderer very much (in terms of friendship). He is 15 years old. His birthday is March 14th. Nothing is known about his family relations, but he is a child who seems like he would survive brightly no matter what happens. There is a rather cute anecdote regarding his birthday. Since his birthday is on White Day, he often receives nothing but chocolates as birthday presents. He is very pure and sincere in everything. He is often fooled by or falls for people's jokes. He especially trusts Wanderer's words implicitly and follows him around, not knowing what the consequences of those actions might be. He seeks to find Wanderer's whereabouts.
