From the comments:

Let's go AHO (Axel-Hakka-Octavio)!!! The super singers of Holostars EN! Let's gooo!!!!

Aho (kansai way of saying baka, or idiot) is quite a fun sub-unit suggestion. The MV even has their names in that order Axel Hakka Octavio for part of it.

Anyway, the EN boys released a cover on Axel's channel, and it's good.
