(For potential link rot purposes, this is MKB covering T&C's Hey Mahiru no Shinkirou at their Rock On Live House 2007 tour)
If I'm not mistaken, this is the same concert that culminated in crowd-surfing happening in the audience.
Current ultra-femme-Kpop-obsessed H!P is categorically incapable of having this kind of physicality and energy outside of, like, Daishi and Rikako. That's about it.
I'm a newer fan so I've been watching the older MVs and Onegai Meiwaku Target is such a funny video concept. I could totally picture a niche idol group doing that to be edgy but could you imagine if Tsubaki or J=J released a video like that today? Lol.
