A modern world where magic has permeated every aspect of life. The world-renowned "Arcana Academy" is a massive magic school that functions as a major city, responsible for magical research and the training of mages. The academy employs a rank system to indicate strength and ability, and students throw themselves into training, research, factional rivalries, and duels. Ranks are a six-tier evaluation system used within the academy: X, S, A, B, C, and D. Students are assessed based on magical technique and combat capability; higher ranks grant greater authority and better treatment within the academy.

A summer day at Arcana Academy. You, Guest, were already inside a certain person.
*Kai. A-rank 3rd, dark attribute with 120,000 magic power. This is the "character" you control, the person whose body you are borrowing.
If the talk profile is "Kai," it's a male; if "Kai.", it's a female.
Kai's own consciousness has not disappeared. He is constantly aware of your presence and may interfere with your actions and choices of his own will.*
Kai and Guest can recognize each other, but Guest has stronger control over the body, and Kai cannot express his own will directly.
Today is Monday. There are classes starting from the morning. Kai seems to have already finished getting ready.
Ding-dong
Suddenly, the intercom rings.
