Nagi Arisuin

Nagi Arisuin is a first year student from Hagun Academy and Shizuku's roommate.

Appearance
Nagi is a very effeminate looking man, having many effeminate features, like soft eyes, and very girlish lips, although this maybe do to the fact that he believes he is a girl trapped inside a man's body. He has very long dark hair, that covers most of his forehead, and goes down all the way his ears.

He is usually seen wearing his Hagun academy school uniform as well. He also wears a religious cross, tied in with a necklace, around his neck.

Personality
Nagi is a very kind hearted person who cares for his roommate Shizuku, constantly encouraging her and supporting her love towards her own older brother Ikki. He also seems to be very analytical, more so then he is leading on, as he analyzed Ikki and told him that Ikki's strength, and his pain tolerance were the same thing, even stating that it will some day destroy him.

New Term, Reunion, and Rebellion
Nagi first appears inside his and Shizuku's room, alongside an angered Shizuku Kurogane over her issues with a certain princess who interrupted her and Ikki's moment together. Shizuku wondering if her love for her own brother was weird, Nagi then gives Shizuku some advice over this issue and decides to give Shizuku a makeover. Nagi is then invited by Shizuku, since her original plan was messed up by an intrusive Stella who invited herself along, wanting Nagi to be by her side, as she gains confidence when Nagi is around.

Nagi and Shizuku, then meet Stella and Ikki outside the front gate of Hagun Academy, where he introduces himself to the latter, shocking them, as they assumed Nagi, being named Alice the entire time by Shizuku, was a girl. The group then heads to the mall, and started to visits restaurants while waiting for the movie to start. After finishing their lunch, Nagi follows Ikki to the bathroom, wanting to know Ikki a little bit better and starts a conversation with Ikki, realizing that Ikki is too used to being hurt to the point he can no longer hear the screaming of his soul in pain. Nagi sensing the surrounding then grabs Ikki and runs inside the bathroom as the sounds of shattering glass followed by guns and screams are heard.

Ikki contacts Kurono, who already knows the situation and tells them that Rebellion has hostages at the food court. Nagi uses his shadow walk ability to transports Ikki and himself to the top level of the mall staring at the hostages, and finding Stella and Shikuzu among them. Nagi then stops an angered Ikki, who was about to go down, showing him the message, that said Shizuku was putting up a barrier. The conflict subsides as Nagi points out to Ikki that Stella had taken care of the rest. Nagi then gets the cops to arrest the members of Rebellion.

Debut Battle and Vow
Nagi is said to have won his preliminary round against an E-Rank within 10 seconds. Although it was unknown what method he used as he never showed any offensive abilities. He then goes to Ikki's match and cheers him on as he fight Kirihara.

Impossible Victory, Decisive Battle, and New Beginnings
Two days after Ikki's impressive victory over Kuraudo, Nagi interrupts, Ikki and Stella's intimate moment, after they were finally able to be completely alone for once. He tells them that Shizuku's tenth round opponent had been decided, Tohka Todo.
