Kunai travels with his allies to the village of Luna, the youngest of the Sisters of the Holy Virgins. Once there, he is suspicious of the church's bad behavior towards the villagers, while Luna's two older sisters don't know how to deal with the unexpected appearance of the Demon Lord.
When Kunai and Akira try to find out more about the reason for his stay in the "Infinity Game", the Satanists suddenly appear on the field to overthrow the holy church and the holy virgins. With the help of his second avatar Zero, Kunai opposes them to protect the city of God and its inhabitants from a sinister ritual.
In the second volume, Kunai also turns the heads of almost all her teammates and opponents in a cultivated isekai manner - and also has to find his way home.
