well, not necessarily. I do believe he (viptenchou is a boy despite the ladylike voice) said he would not sing anything unless he allows it with his friends. The two of them sang Heart a la mode back in the summer of 2016 i think but since then he has not uploaded any new songs by himself nor used any social media accounts so i dont think he is coming back....sorry about that.
but if you look out for 96neko's uploads, maybe you can find new uploads featuring viptenchou! Hope this is ok
