I was going through old YouTube and I found this metal artist/idol/wrestler called Ladybeard again. It felt like a wave of nostalgia and his music is very uplifting and motivational and his image helps back it up a lot. If you're looking for metal/j-pop that isn't BabyMetal to feel better about yourself to, I recommend Ladybeard and his projects with LADYBABY and his Deadlift Lolita project! https://youtu.be/LKwvtF1Y6Pw
(my personal favorite. helped me get over my dysphoria when i was but a wee trans boy)
