Here's a cleaned up version: 「ぷちゃへんざレディオ」
And the original (From My Hero Academia vol. 4 back cover):
It's quite distinctive, so I hope someone can help. The other font that can be seen in the image (reading Present Mic) I've identified as Blippo Black, so it seems likely the other lettering is also done in a readily available font. I've had no luck browsing Japanese font sites, and en.likefont.com didn't seem to have it in their database. Even suggestions for other font identification services with Japanese support are appreciated. Thanks!
