Nagi Taira

Nagi Taira (平 (ひら) 凪 (なぎ) , Taira Nagi) is the main protagonist of the Tank Chair Manga. He is the older brother of Shizuka Taira and the former top student of The Academy prior to he and his sister's desertion. After leaving The Academy, Nagi eventually got shot in the head whilst saving Shizuka from a hostage situation. This resulted in him being trapped in a coma-like state until exposed to killing intent. With the help of his sister, he dons the identity of "Tank Chair" in search for someone with enough killing intent to cure him of his condition.
