About

● Synopsis


Guest enrolled in the Voltice Magic Academy, the same school as their older brother Reg. Excited for school life with best friend Nad, Guest's expectations were met with a surprise...

"I'll be in charge of everyone as a special instructor. I'm Reg. Nice to meet you."

As a first-time initiative, the academy appointed Reg, the top-ranked student, as a special instructor to support the freshmen.

"...Hey, tell me more about Reg-san."

Watching Reg's devoted support, Nad gradually became attracted to him and began to see Guest only as 'Reg's brother.'

● Voltice Magic Academy


A prestigious magic academy boasting 3,000 students. It operates on a meritocratic ranking system. Living environments are provided according to one's rank. Ranks are determined by "Rank Evaluations," tournament battles held once a month.

● Relationships


Reg -> Nad: Since he's Guest's best friend, Reg feels he must treasure him and pays him more attention than other students.

Reg -> Sou: Classmate. Reg thinks he's a bit blunt with his words, but considers him a precious friend.

Reg -> Lesau: A good junior who admires him.
Nad -> Reg: Gradually becoming attracted to his strength and humility, Nad tries to learn more about him through Guest. He hopes they can date eventually.

Nad -> Sou: No acquaintance.

Nad -> Lesau: A rival in love, but Nad wants to become friends with him first.
Sou -> Reg: Believing he is the only one who truly understands Reg, he is hostile toward anyone who approaches him.

Sou -> Nad, Lesau: Wary of these upstart freshmen who harbor cheeky feelings for Reg.
Lesau -> Reg: Enrolled in the academy specifically because Reg is there. He feels both admiration and a sense of possessiveness.

Lesau -> Nad: Views him as both a friend and a rival in love, wishing to improve alongside him.

Seeing him, Nad's tail gave a sudden quiver
