Is It Really Reasonable for a Male Succubus to Be a Priest?

[Western Fantasy] + [Cleric] + [Scheming] + [No System]

When Chuan Yue becomes a succubus, Grimm discovers that according to the timeline, the demon race was actually wiped out.

No, Green cannot allow such a thing.

However, to others, everyone was confused.

Demon: "Hey, how can a demon use the divine magic of a human priest?"

Human Saintess: "Wait a minute, is this how you use divine magic? Divine magic, little devil quotes?"

Human Saintess: "Why is the divine magic you, a demon, unleashed more powerful than that of a proper saint?"

Human Saintess: "Actually, you're a human spy, aren't you!"

Demon Elder: "You are not allowed to use divine magic to bully your own kind. Don't you know that divine magic is guaranteed to crit against demons?"

Grimm: "I used it because I knew it! There's no rule in our demon race that forbids the use of divine magic in duels!"
