Mutsugoro’s Mucchan Manjū is real: https://matcha-jp.com/en/4989?page=2

Default audio/sub tracks are for whites and people who can’t have fun.
Kindly switch to the secondary audio/sub tracks for a cultured experience.
There’s also a sub track without honorifics.

Big thanks for XiaYixuan for OP/ED TL and Wafflesama for encoding.
