Yes, he’s Sakito, the guitarist of Nightmare! He’s always been pretty cute but I think old looks wasn’t hitting his true slay-tential, if that can be a word. I feel like especially in the early years he was more reserved, though he did have a nude magazine spread (save for his guitar and nicely placed fabric covering his modesty).
I think it was in recent years through his side project Jakigan Meister that he got really edgy and spicy 
Now, he’s just slaying left right centre! Midriffs all day every day, harnesses here and there. you can see em in the new Nightmare looks. Lemme link the threads here in an edit later. For now, here are some pics
That’s him in red:

Sorry these are grainy af FB links I’m pretty sure there should be better stuff online…but thank you Tooru Yoshida for uploading them (he does keyboard stuff for Jakigan, Nightmare and also MUCC)
This is Sakito in a pretty delectable SPICE article, I think he did a photoshoot in a cage for this outfit as well.
Here is Sakito, well, self-explanatory here:

can’t remember the source, but I’m p sure for this coordinate, at least one of the photos must have come from kyokobarbie. Amazing stylist lady who’s done stuff for LM.C too.
