I know of Wave but never did get into the anime.. never knew it had songs too..
In fact.. i was salty towards it because it was the project that took the artist away from Mermaid Boys.. (yep that is still on hiatus.. if not then more than likely cancelled.. Edit: 2016!!!?? WHAT THAT LONG AGO!!!!) (Mermaid Boys first started that year.. ToT yep cancelled.. almost a decade.. it started..))

Anyways *Cough* i think Tomoaki Maeno is in there too? i recognise his voice... had a hard time finding Jin Ogasawara's though.. XD eventually found it though. <333
