Itsuki Akasawa

Itsuki Akasawa is a classmate and rather a mischievous friend of Amane, and Chitose's boyfriend. His birthday is March 4th. He is one of the few friends Amane made after leaving his hometown, and is a lively and good-natured young man. After learning about Amane and Mahiru's relationship, he takes on the role of encouraging and advising the shy Amane in matters of romance. He affectionately calls Chitose "Chii" and is so devoted to her that he considers their relationship with marriage in mind, which causes friction with his own father. Although they are now recognized as a lovey-dovey couple throughout the school, during his middle school days as an honor student, he was fervently pursuing Chitose.
