I received a question about the name of M5ism, I comment.

Memyou introduces itself as エムゴレニズム(emugorenizumu) with me in Japan,the notation in English is M5ism.
"M" is an initial of 目猫(Memyou).
"5" is 五連(goren) meanings that are my name.
There is not other implication, but we like this simple name.
