The Demon King Will Die in 100 Days

A world founded upon teleportation magic! A god who has left his people! A nation of demons with strange and mysterious powers!

Naiouyubi went to another world in search of magic with the power to defeat the demons, but has he returned unchanged? The other world had no special spells, so will Yubi be able to complete his goals?

One way or another the Demon King only has 100 days left, but what happens before then is anyone’s guess!
