Ayase Riku♂

A first-year student who transferred into Amatsuchi Academy during this awkward time of year that can be called neither spring nor summer. (Although he himself isn't very aware of it, accepting a transfer student is an exception among exceptions, the first since Amatsuchi Academy was founded.)

Until this spring, he lived in Tokyo, Japan. Both of his parents were involved in the investigation of Amatsuchi, while he himself was born in Yozuha. When he was young, he lost his parents in an accident while they were investigating Amatsuchi, and was taken in by his grandmother (his father's mother), who lived in Tokyo, so he has no memories of that time. Because of those circumstances, he doesn't have a very good impression of Amatsuchi.

His family has run a swordsmanship dojo for generations, and his father also made use of those skills while active in Amatsuchi. He himself is also highly skilled with the sword (his grandmother was his teacher). Since he is fundamentally and decisively out of sync with the seasoned adventurers, he is often teased and messed with.

Although highly skilled with the sword, he's generally ill-fated, and just a little unfortunate.
