Асано Ікуя

Ikuya Asano is another one of Youko’s classmates who is transported to the kingdom of Kou. He goes missing after a battle between Yuka and Youko and is not seen by either of them for some time. Asano eventually becomes part of a group of Shusei and works for them as they traveled through the kingdoms. However, being in a completely alien country and lacking the ability to speak or understand the language, the strain has taken a toll on his sanity. Eventually, Asano questions the reason he was ever brought to Kou and seemingly can't find a reason for his life to go on. He dies at some point later in the anime. In the novels, Asano does not exist and Youko attends an all girls school.
