Shin Wolford is a boy, who used to work in an office in Japan, but after being killed in an traffic accident, is reborn in another world, where he learns magic from his adoptive grandfather, Merlin, and grows up sheltered from the world.
Long ago, a person became a demon
and nearly destroyed a whole nation.
Einst verwandelten sich Menschen in
Dämonen und richteten das Reich zugrunde.
Hace mucho una persona se volvió demonio
y casi destruyó toda una nación,
Autrefois, un humain démonisé,
un démonoïde, a ravagé un pays…
No passado, uma pessoa se tornou
demônio e quase destruiu um país.
