[Machine Translation] There, in a different world of swords and magic, a gigantic underground labyrinth awaits. Beatrice, who has risen to the position of the most powerful magician by managing magic in a game-like way that is much more familiar to her than spells and magic circles, is troubled, however. What is the identity of "Bubu," the legendary man who wields even a "sword saint woman" in a single nap? There is also a giant dragon with a four-digit figure, and a girl with a long life expectancy, but overall, what is going to happen in this otherworldly exchange?

そこは剣と魔法の異世界、待つのは巨大極まる地下迷宮。呪文や魔法陣よりはるかに馴染みのあるゲームライク方式で、魔法を管理し最強の座に上り詰めたベアトリーチェは、だが悩んでいた。お昼寝ひとつで、カンスト組の“剣聖女”さえ振り回す伝説の男『ぶーぶー』の正体とは。あとなんか四ケタ級巨大ドラゴンとか偉そうなご長寿少女とか出てくるけど、全体的にどうするどうなる異世界交流!?
