From MangaHelpers:
Summoned into an alternate world of Alayzard, Ousawa Akatsuki helps defeat the demon lord, brings harmony back into the world and, under the demon lordās last request, takes the demonās only daughter back into Akatsukiās own world. It turns out that being teleported into a different world is somewhat of a common occurrence. Those who find themselves back home often come back with the power to use magic and the world organization fearing people like Akatsuki created Babel, a school to teach and keep tabs on the magic users. Akatsuki is able to pull the demon lordās only daughter into Babel as his sister, Ousawa Miu. A new chapter for Akatsuki is about to begin in his own universe. [vyc]
