Ren Nagase

With only a year left to live, 17-year-old Akito finds new meaning in life by bringing joy to a terminally ill girl who has just six months remaining.

Aki, Ryo, and Yuta grew up on a tiny Japanese island with Fureru, a small yellow hedgehog with mysterious powers. Now in their 20s and chasing a fresh start in Tokyo, the trio tries to build new lives while keeping their unusual companion out of sight. But as Fureru's powers awaken, buried emotions and old tensions reemerge, pushing their friendship into unpredictable new territory.
