The world’s most skilled Sword-God (♂) and Witch-Emperor (♀)
who had saved people many times, fought fiercely
in order to check each other’s strength. And then
when all of a sudden they decided to marry and the world was made a fuss
they suddenly disappeared. Three years later, in the Demon Forest
which is said to be the graveyard of adventurers, there were a couple and their son
Ryuku. He was still a baby, but when he imitated his mother to cast magic
how easy it was for him to use magic!! After that, Ryuku
who inherit the talent of his parents and wonderfully developed his power
on swords and magic, goes on a journey alone.
The sisters he meets along the way take him to the guild
to register as an adventurer and determine his rank
but the result is the strongest SS rank!
