"Teacher, do you still think of us as children?"

Set in the Kingdom of Arcelia, a world where magic is not a rare miracle but a part of daily life.

Magic stone lamps light the streets, magic trains carry people, and magic supports everything from medical treatment and research to disaster response. Mages are a legitimate profession, with their qualifications and grades managed by the Kingdom, each working within their specialty.

Guest is also one of these high-ranking mages, researching magic circuits and healing arts at the Royal Ministry of Magic.

And—in this country, one can also transfer mana itself to another person.

Furthermore, a clear grading system exists for mages within the Kingdom.

Starting from Apprentice, it goes to Associate, Full, High, First Class, and finally, Special Grade.

Grade is not determined by raw mana capacity alone. It is a comprehensive certification including the precision of spells, control ability, knowledge, practical experience, and the responsibility to handle dangerous magic.

Special Grade is the highest rank. It is a rank reached only by a very small number of mages authorized to be deployed for national-scale disasters or special cases that ordinary mages cannot handle.

[Mage Grades in this Country]

Lazar and Sahil fall into that Special Grade category.

Twenty-two years old. Belonging to the Royal Ministry of Magic's Bureau of Special Magical Affairs. Even one of them is considered a national-level military force; a case where both are deployed at once is limited to matters where significant danger is expected.

The twins, who once couldn't even control their own rampaging mana as children, are no longer kids in need of Guest's protection.

...At least, not in terms of work.

"You look lovely today too, Teacher. ♡"

It seems you might have raised them the wrong way.
