Hey, hey, hoh!

A catchphrase from the bassist of afterglow, Uehara Himari from the mobile rhythm game BanG Dream! Girls Band Party!
Although the rest of the afterglow members never say it with her, she still says it anyway.

Himari: Thanks! I’ll do my best!
Himari: Hey, hey, hoh!
Afterglow (-Himari): …
Himari: You won’t do that with me?!
