If is formed in Osaka (大阪)大阪.
If disbands
If was a visual kei band in Osaka. They were active in 1999 and are now disbanded.
Looks to me like the ex-La'Mule band is being conflated with the Vice Versa band. I think the “If” belonging to guitarists NAO and SIN is a different band (whose full lineup is unknown?). I'm going to go ahead and split them.
Funnily, it does appear that DEZI used to go by Nao, so this band could have had two NAO's if he'd kept that name 💀
