The Summer Hikaru Died

After sleeping for two full days, Hikaru finally wakes up—much to Yoshiki's relief. But Hikaru is clearly weaker than before and now feels pain. As Yoshiki and the others reel from a sudden attack by a mysterious man wielding a seemingly cursed sword, Tanaka confronts Takeda. It seems Tanaka has his own objective—one that goes beyond the mission assigned to him by his company...

Though hesitant, Yoshiki asks his father about the Indo family's murky past and secret ritual. Later, Hikaru loses control at school and feels deeply shaken.

While everyone else attends the school assembly, Asako finds Hikaru wandering the halls. Alone at the beach, Hikaru reveals his final plans to Yoshiki.
