warning: small spoilers ahead !! Just found out a hidden gem, the story revolves around a "what if" and apocalyptic themes. What makes this very eye catching is the protagonist, Mitsumi and the little girl called Luna have more character depth in a one-shot. Most one-shots lacks how to connect with a reader to a character but it gave a lot of impression. From Mitsumi's backstory to how he have gone through from the past years letting people go being ignorant to standing up on his own. The story is kinda predictable but the whole concept of it is very interesting, I wish this is longerto talk about the on going disease or will they ever find a cure to it?
