Kono Oto Tomare! Sounds of Life (2019)
* Based on a shounen manga series by Amyuu. From having only one member to now having seven, the koto club has grown a lot. But while the team has evolved, their loss at the music festival means they have a long road ahead—especially, if they want to make their dreams of making it to nationals a reality. These underdogs are ready to find their sound as they navigate school, koto practice, and their relationships with one another. Source: Funimation
Theoretical best: JPN BD+GHS*
AM11 is GHS (JPN BD Encode+modified FUNI) with dub and episode 14 patch applied *GHS has ESL edits which should be reverted, also the KFX is very ugly so probably just remove it
