Hey love your story. Only thing that irks me is his lack of weapon skills so i just want to suggest one that i think would fit the character. Whip skill essentially uses a mix of mana control and I believe he has a skill that makes his good at pleasing with his hands don't remember its name. the use of them at the same time unlocks an ability that allows him to strike erogenous zones instinctually with his whip bringing Pleasure greater or equal to Pain given. Higher whip ability the faster he can strike consecutive areas rapidly and higher mana increases the amount of pleasure each strike gives. Feel free to use this idea as you please.
