Shuuji Miwa

Miwa is the close-range All-Rounder and leader of Miwa Unit (A-rank #07). He is also one of the eleven candidates for Yuuichi Jin's Fuujin.

Miwa is the quiet type; he doesn't talk much and always has a serious expression on his face. Following the death of his sister, he developed an uncompromising hatred for Neighbors, and demonstrates aggressive, even violent behavior where they are concerned. When Yūma admitted to being a Neighbor, Miwa shot him without hesitation (although the attack would not have killed an individual in a flesh and blood body, only caused them to faint). He despises Tamakoma, especially Jin, due to their Neighbor-friendly views, and he considers them traitors to Border's cause. After Yūma was accepted in Border, he fell into a short depression due to no longer being able to understand whether his hatred is justified or not.

After learning about Jin's past and the events of the Large-Scale Invasion, Miwa started to show a bit more concern about those around him, particularly his fellow agents, while retaining his serious personality.
