Tsurugi is a friend of Hyde’s from school and a prominent member of a vigilante group called the EFG.
The EFG’s main objective is to defend their fellow students from the evil influences of wielders, so they tend to avoid dealing with the Night. However, the Final Night is a different story.
In order to protect his classmates–not to mention the rest of the world–Tsurugi decides to confront the root of all evil: the Re-Birth.
