Gad Guard Opening and Ending Songs

I’ve searched and searched…
Even looked for both the Opening and the Ending~!
As well as the artist

Opening- Boomerang Boogie- Pe’z
Ending- A Song for my Buffalo- Pe’z

…I even checked google… and still looking.. ._.;;;;

I have the anime OST
But I was surprised when it didn’t even have the TV size of the Op and Ed

..If anyone can find them for me…
I’d love you to death…!

~Cheers!
