Rifujin Na Magonote: 4 books

Teleported to an unfamiliar land by a mysterious magical disaster, Rudeus and Eris are going to have to rely on their own wits to survive--and on each other! Which is easier said than done, especially when they find themselves face to face with one of the Superd, the murderous demon race Roxy warned Rudy about...

Kicked out by his family and wandering the streets, an unemployed 34-year-old shut-in thinks he’s hit rock-bottom--just as he’s hit and killed by a speeding truck! Awakening to find himself reborn as an infant in a world of swords and sorcery, but with the memories of his first life intact, Rudeus...

Rudeus is shipped off to Roa, the largest city in the region, to tutor the young daughter of a noble family. Unfortunately, what he thought would be an easy job proves the exact opposite once he meets his student, Eris--a fierce-tempered hurricane who blows Rudy’s optimistic expectations to bits!...

Continuing their journey, Rudeus, Eris and Ruijerd have a run in with a figure from legend--none other than the Great Emperor of the Demon World, Kishirika herself! When the trio lend her their aid, Kishrika rewards Rudy with a strange new power...one that might just be more than he bargained for.
