Summer Time Rendering — Characters & Cast

Uncover the truth behind Ushio’s death, protect Mio and the islanders, and break the cycle of time.

Shinpei begins as an emotionally detached, observant young man who fled to Tokyo to escape unresolved family grief. Forced into a recurring cycle of agonizing deaths, he transforms into a resolute, calculating commander who embraces sacrifice and steps beyond human temporal boundaries to save his loved ones.

Protect Shinpei and Mio, reclaim her lost identity, and stop the mother Shadow Haine.

While human Ushio tragically dies before the series opens, Shadow Ushio emerges as a defective copy that retains the real Ushio's soul, conscience, and fierce loyalty. She evolves from a confused apparition into the vanguard of humanity's fight, ultimately rewriting history at the source.

Avenge her brother, uncover the island's dark truth, and eliminate Haine.

Returning to Hitogashima to settle a 14-year-old vendetta regarding her twin brother Ryunosuke's murder, Hizuru shares her body with Ryunosuke's lingering consciousness. Over the course of the story, she transitions from a solitary avenger into an indispensable tactical anchor who entrusts the future to the younger generation.

Protect the island's surviving youth and eradicate the Shadows once and for all.

An aging island huntsman bearing deep personal scars from the Shadows' past predations, Nezu operates as the tactical backbone and marksman of the resistance, providing essential island knowledge and lethal firepower.
