The Summer Hikaru Died Episode 10 English Dubbed Episode Title: Truth Episode Description: The Hikaru entity overruns the room and attacks Yoshiki and Tanaka until Yoshiki reattaches Hikaru’s head and collapses. Yoshiki wakes in the hospital, where Takeda is blamed for the attack, while Hikaru remains unconscious with faint signs of decapitation. Tanaka hints at his blindness and desire to reach the impurities’ world, and Rie later describes a tunnel filled with headless bones, matching the neck-deformed impurities. Hikaru awakens, sensing something unusual about Tanaka’s sword, and returns to school, where Nonuki/Unuki is revealed as a forgotten famine deity tied to mercury mining, abortions, and the Indo family’s sin. At a temple, Hikaru recalls head sacrifices and body parts buried around the village, though the family’s crime remains unclear. In the post-credits scene, Hikaru nearly devours Yoshiki’s soul but resists and leaves him shaken.
