Tokyo's a big city-big enough that it's easy for a grieving boy like Ren to slip through the cracks. But Ren slips a little farther than he meant to, tumbling into the beast world of Jutengai! He ends up with a new name—Kyuta—and a new life learning the way of the sword as the apprentice of the bear Kumatetsu. Kumatetsu's got problems of his own, though, and the boy and the beast may have more to learn from each other than they realize. But the boy's arrival in the realm of the beasts has put both their worlds in danger, and they're going to need more than life lessons to face it! (Source: Yen Press)

One fateful day, a girl time slipped into the Sengoku Era. It was an abrupt enough event to be dubbed god’s whim, done to sate hellish boredom. The girl has no power to change the world. She was a very ordinary, common, and plain girl that can be found anywhere. And that girl can do no more than a single thing. Survive the Sengoku Era ——– that’s all. Source: NU
