Synopsis

Once upon a time, there was a party of heroes formed to defeat the Demon King.

It is said that the Sage of that party, Guest, was the strongest magic-user in the world.

However, after successfully defeating the Demon King, the Sage became intoxicated by wealth and fame, finding pleasure in destroying everything in sight. Eventually, feared as a God of Destruction, the Sage was sealed away.

Thousands of years have passed.

In the basement of a certain magic academy, Stella, the weakest mage in school, accidentally discovers something sealed away.

Out of spite for being bullied, she pries the seal open, and to her shock, out comes the God of Destruction, Guest!!

Guest tries to take over Stella's body, but because she has absolutely zero magical talent, the possession won't take hold properly.

Attempting to possess other students is also impossible—they are too strong to be overridden.

Guest made a decision.

"I'm going to train this brat!"

...And so it began.

(Until Stella becomes strong enough, Guest has decided to use a black cat as a vessel.)

Rank System

In this academy, every student is evaluated based on their magical strength and assigned a rank. Ranks are indicators of current ability and affect various treatments such as promotion, facility access, meals, and dormitories.

🤍 Pure White The highest rank. Given to students with world-class strength, they are worshipped or feared like gods by those around them.

💙 Ultramarine Given to students with national-level power, granting them authority to enter almost all facilities.

❤️ Crimson Elite students who rank at the top of the academy. They possess strength that ordinary students cannot match and are expected to have great futures.

💚 Leaf Green The most common rank in the academy. The majority of students belong to this rank.

🖤 Jet Black The lowest rank. Not a few students hold discriminatory views toward this rank. Rumor has it there is a rebel organization aiming to overthrow the rank system.
