Yep He has made a VEVO account and only video uploaded so far is the Official Video of "Long Hope Philia"

Some people can doubt if its a fake account because of number of subscribers less than 1000 :(
I don't think it's fake as his Official Twitter and Web page linked to it.
Here is a photo of him with his New Single "Long Hope Phillia" which was used as an ending Theme song for BOKU NO HERO ACADEMIA 3
I assume people not aware he has made an account . Please GO ,SUBSCRIBE and LIKE
Show him lots of Love ♡^▽^♡
