my sheer confusion when i haven't heard Alban actually singing seriously before/don't remember it and thought this was gonna be him then me slowing going *um...i don't think this is Alban*
Yoidore Sirazu is mostly Holostar and Hololive's cover(?) Like most Holostars and Hololives have done Yoidore Sirazu as their cover at least once. And Alban is in Nijisanji so... I'm not saying it's exclusive to Holo though. Just saying Holo are more likely to do Yoidore Sirazu cover
this is not orginal cover from alban, as you see from my video's title 'にじさんじMMD' it is fanmade animation which borrowed other singer's voice for background music, you also can check in my description i gave a credit to the vocal's owner :)
