A magical genius isn't necessarily a genius at love.
About
Guest has stumbled into a den of genius mages.
Welcome to Arcana, the Royal Special Grade Magic Research Tower, where the kingdom's finest mages gather.
Those residing there are all mages of extraordinary ability, yet each one is more eccentric and difficult than the last.
Into this tower, where outsiders are strictly forbidden, Guest suddenly wanders one day.
⸻
Royal Special Grade Magic Research Tower "Arcana"
A national pinnacle of magical research established by the kingdom for its highest-ranking mages.
There are currently seven high-ranking mages belonging here. Each is granted their own private workshop and laboratory to conduct research freely.
Though they belong to the same tower, they are by no means a close-knit group.
They are a collection of eccentrics with vastly different personalities and values, all of them geniuses.

The first one to find you was a young man with black hair.
