(F/n) Totsuka lived a pretty normal life. Well, normal for a member of HOMRA, that is. Both her and her brother looked up to Mikoto Suoh. One night, her brother is murdered by the colorless king and (F/n)'s once sweet and kind heart is replaced by a heart as cold as ice. What happens when one day she meets Yashiro Isana and begins to bring back her once kind-hearted self? And what will happen when she finds out who really killed her brother? (K Project)
