[Transformation] + [Never Marrying] + [Saintess] + [Succubus]

Transmigrating into Selenan, the spoiled young scoundrel of the "Wholesome" world, his identity is that of a washed-up descendant of the saintess bloodline, and right from the start, the plot has him fated to fall into becoming a succubus. To avoid becoming such a shameless race, and to preserve what little male dignity he has left, he chooses to fight back with everything he's got...

So there he is, shouting about bonds and justice and other things nobody can quite understand, charging straight into the demon army that's trying to turn him into a "plush ball"...

His courage earns the approval of his childhood friend, and his conviction earns the praise of the gods, so the gods reward him by awakening his bloodline...

"So can somebody please tell me, why did awakening my bloodline turn me into a saintess?"

Facing the trolls closing in around her, eyeing her like prey, the elegant young saintess's face...
