Anime House presents Studio Gokumi's reverse isekai comedy directed by Kiyomitsu Sato (including Full Metal Alchemist: Brotherhood) and Hiroyuki Hashimoto (including Is the Order a Rabbit?), with a script by Makoto Uezu (including Assassination Classroom, Konosuba) and a theme song by Kizuna AI.
Humans have long suffered under the dark rule of the demon queen Valvaran. Finally, the knight princess Arnelia and a small band of loyal followers dare to take up the fight to liberate the world.
They are outsiders, shunned and feared - the heartless berserker; the mage who pursues obscure studies; the heiress of the Assassins who lives only for her martial arts. They actually succeed in cornering Valvaran. But when the demoness tries to escape to a new life in another world, the magic also takes hold of her opponents - and so they all find themselves in present-day Japan.
Arnelia's liberation army finds shelter with the student Kumi and quickly makes friends with her new existence - a world in which there are comics, games and YouTube and you can just hang out is very much to their taste. Only the knight has not forgotten her original mission. Because the Demon Queen is not to be trusted, even if she now looks like an innocent little girl.
