Raika/History

Background
Raika is a 21-year-old without a career who lives in The Hidden Condo where he shares room 602 together with Fina who is in charge of providing him with shelter, food and clothing in exchange for Leica serving as a means of air transport and serving several errands, since he has a flight license and is very good at it.

Interspecies Relations arc
Raika attends, together with Fina, the rice cake grill organized by Legoshi, where she introduces herself and coexists with her neighbors.

Later, Raika is seen along with several of her neighbors discovering Legoshi bringing Haru to the Hidden Condo when they spent time in Seven's room and greet them, then try to guess what the relationship of these two is, only reaching the conclusion of that Haru is important to Legoshi.
