Shunsuke Otosaka

Shunsuke, the older brother of Ayumi and Yuu, is a fascinating character with a bittersweet story. In a future flashback in Episode 9, we learn he used to have the incredible ability to leap through time—though it came with a catch: he needed to see clearly with both eyes. Unfortunately, his power came at a price; now blind, Shunsuke explains that every use of his ability slowly robbed him of his sight. While he can no longer wield his time-leaping powers, his brother Yuu still has that gift, ready to jump back and save Ayumi from whatever awaits her.
