Sensei gates singing he usaul y doesn't sing he used to sing to his son's but stopped he has a mix voice to
April is a soprano she loves singing and is brave when she does
as a group they'd make a pretty good choir with Mikey being an excellent echo April an excellent soloist and the others are amazing this is when Mikey let's his voice stick out because he doesn't think no one noticed him
that's about it ._.
