Dos vidas acabadas en un mundo, reencarnadas en otro, dos poderosos guerreros están por hacer historia como los nietos de un sabio mago.

Shin has a sister. They're both reincarnations who died young, reborn in a world of swords and magic. Adopted by the Wise Man, Merlin, they've spent the past 15 years learning nothing but magic. Overpowered and clueless, they're about to be unleashed on an unsuspecting wolrd.

What if Shin in his past life was not alone in the accident... Disclaimer: I don't own Kenja no Mago

In modern day AU, there exist a man wrapped around the fingers of a healing saint.

It includes three days of forest camping, alone time with favorite girl, and annoying uncle and friends.

A mysterious omen appears, and the tenuous peace between humanity and demonkind is suddenly put to the test. Shin and his friends must uncover his family's darkest secrets in order to prevent an artifact of untold power from falling into the hands of a renegade group of devils, who are apparently after the same thing as well...
