I met Shizuku, and I finally remembered. What kind of adult I wanted to be. The desire that I myself tried to run away from, to rebel against, to throw away…


Nagi Arisuin came from an orphanage in Eurasia with his best friend Yuuri who soon died after both their government officials and mayor hired a gang to "clean up" their streets. He saved all the children from the orphanage after killing the gang, but all the kids soon became afraid of him. Nagi joined Rebellion under the teaching of Wallenstein after both killing the mayor and sending money to the orphanage.

Nagi became known as the Black Assassin and was later sent to Hagun Academy as a first-year for the upcoming 62nd Seven Stars Sword Art Festival as one of the students of Akatsuki. He became the roommate of Shizuku, then befriended her brother and Stella causing his eventual betrayal.
