I think having all of his three skills and NP boosts his attacks is a little bit legit overkill. Assuming that he's facing a Demonic-type enemy (which, automatically has Evil alignment), he's going to deal +150% damage, +30% NP damage (and another +150% damage to Demonic), and 50% Buster performance. And even without facing Demonic and Evil enemy, he's still going to deal +50% damage, +30% NP damage, and 50% Buster performance.

And also the effects of the skills just make him a straight up upgraded version of Altera (minus her heal), not to mention the ridiculously low cooldown for that many effect which, for his 2nd and 3rd skill, lasts for 3 turns.

Honestly, I hate overpowered servants like this. Maybe you could add some other flaw to him like, really low base dmg stat meaning that he's really bad when his skills aren't up but really good when they are, or bad NP gain, or low base HP like Jalter, etc etc.

Also like Valeth, applause for not genderbending him.
