Originally licensed and release by NIS America, they’ve brought it over to Crunchyroll to get some additional eyeballs on it.
Add another show that’s been under the radar and likely not getting more made with the arrival of Daily Lives Of High School Boys on the Crunchyroll service.
Plot concept: Tadakuni, Hidenori, and Yoshitake are students at the all-boys academy, Sanada North High School.
