Dungeons and Adventurers. A fantastical topic that suddenly became real on Earth ten years ago. Everything changed since the appearance of these mysterious areas that spawned monsters everywhere, and people all over the world acquired Skill Boards to combat these monsters.
Mizufune Mikoto is one of those hopefuls who wants to become an adventurer, but sadly her Skill Board is empty. Since that revelation, she spends her days making dungeon models with cardboard boxes to entertain herself...
Casimir Toomes has been pretty successful as an adventurer... until he wasn't. With his team shattered and the surviving members scattered to the four winds, he went back to his home country of Anima, and at his Master's behest, became a teacher at the Academy of High Magic.
Sure, his Master keeps bugging him to take on some personal students of his own, but he's not in this teaching gig for good, it's just a temporary thing, as a favor.
There's absolutely no way he'll get attached to any...
