Shiki Toono sustained a life-threatening injury that wiped fragments of his memory as a child.

Years later when Shiki is in high school, his father dies and he is ordered to move back in by his sister Akiha, who is the new head of the household. However, Shiki holds a huge secret.

When she suddenly showed up beside him later alive and well, she asks him to be her bodyguard! Thus, Shiki's journey to unravel the mysteries of his past begins...
