Okay so I’ve kinda figured out what his stand ability is, (with the help of my dad 💪💪) so with the syringe that’s at the end of his stand’s tail he can paralyze his target, and he can stab the target and the target won’t go down with just one stab but they’ll feel kinda like when your leg is asleep but you can still move it but with each stab Tenshi will have to refill and to do that he’ll have to kinda stab himself in the stomach where he stores the poison and doing that he becomes vulnerable ofc, and the more he has to refill he becomes fatigued (so the liquid is both a posion and his energy/health) and because he’s needing to refill over and over again he’ll become frantic and miss his target if he doesn’t concentrate and a fun detail added by twin (we had discussed that he totally gets hallucinations of his dead wife occasionally) when ever he starts getting frantic he’ll see her and he can’t hear her say anything and he knows she’s dead but it’s enough to distract him but because he KNOWS she’s dead
