Experimental subjects is a go. Enhancements I’m limiting to magical high-speed regeneration as that seems to be the main thing you’re after. The rest can be light side effects of the enhancement, but still easily within the bounds of trained, athletic humans. Nothing on par with a Daeva and such.

Traditionalist Japanese spellcasting curriculum sounds fine with all its spell varieties. I’d still impose the routine magical suppressants the facility will have given him to help deal with the conflict in magical energies if he’s both magically gifted and enhanced. I’ll add that bit to the info blurb later, too, to be clear.

Needs to constantly eat to upkeep body functions is fine, but if that’s going to be a [i]real[/i] check against high-speed regeneration it needs to be something like he physically cannot move anymore if he’s hungry for even just a few hours as a result of his body constantly consuming too many nutrients. Left for too long like this and he’ll be stuck in some endless cycle of regenerating while his body digests itself and so forth.

Hunger pangs would be a bitch.

Let me know if you want to tweak anything to adjust. [@Cu Chulainn]
