Okay, so ZORO previously went by ゾロ before Taizo and Yuuya left(and then they changed once POLICE came out), so the main picture for this tag really shouldn't be Ryuuji and Tapi, amiright? I think it confuses some new listeners here. The duo goes by ZORO not ゾロ, friends!
@Shirashusuka They've start using ZORO as their name when Taizo and Yuuya left the band. So, basically, you may use ゾロ for all the things before POLICE single, and ZORO for POLICE and forward releases.
