The Only Mortal in Heaven — Episode 6: Marked by Him

In a pavilion floating above the clouds, surrounded by trees in bloom, Angel finally tells William the truth. Yes, she does it too. Angels pass mana to one another so they won't starve. It is a duty, and she is not supposed to enjoy it. "But with you, I'd want to try it for real." He wants the same thing.

Her kiss is sweeter than he imagined, and soon the white lace and the shyness slip away. When it is over she is glowing, quite literally, with golden marks swirling across her skin. Too much mana, she guesses, the same way Asmodea got her wings back. She is more than fine, and she says the view made it even better. Then they walk back hand in hand and run straight into a golden-crowned archangel, with Angel's new marks impossible to hide. Episode 6 is the sweet payoff, subtitled from start to finish.
