The Summer Hikaru Died

Yoshiki introduces Kurebayashi to Hikaru. If the impurities continue to spread, many more people could die... Kurebayashi, who once experienced the heartbreak of her late husband "coming back" as an impurity, asks them what they want to do. After hearing their answer, she agrees to help them. Meanwhile, Tanaka—after a chance encounter with Yoshiki that gives him a lead on the entity he's been searching for—begins to make his move...

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.
