A summoner infiltrates the Church of the God of Light and poses as a believer.
And then this happens:
The white-haired Divine Son of Light, compassionate and devout, the god's most faithful follower and revered emissary who walks the world in the god's stead, chants softly.
[O God, please answer the prayers of your faithful believer.]
"Rumble!"
After the deafening blast, the great villain, moved to close his eyes and pray devoutly, turns to ash.
Everything within five miles is leveled.
His teammates stare in shock. "What are you doing? He'd changed!"
The Divine Son of Light lowers his eyes in regret. "I know. I sent him to meet my god."
He can repent in heaven.
Reader advisory: The protagonist is righteous to a terrifying degree.
