Already, so many people voted up tag 'saikorokorojo' as an artist's name, but I think it's 'saikorokorosuke' exactly.
Edit: @lokioro
Thanks for fixing. indeed, the kanji '助' can read 'jo' in many case, but if it's used as a part of a person's name, it's right to raed 'suke' in most case.
Mrm, I couldn't decide which reading was more accurate (minimal kanji knowledge), so I just picked a random one, I'll go ahead and see if I can fix it.
