I'll check it out, thanks!

Ah, there's another video here in which i freely use dodge/airdash. Not sure if that's what you mean, but Choir's around the 10m30s mark.

And i'm not sure if people should be learning anything off these videos. The way i played was very risky because i went full yolo :v. There are also some missing attack patterns, since i sometimes i'd get 'lucky' and the bosses didn't use them. I updated this video's description with the one from this fight.

Hey, you should update a Choir video even if you do dodge... It's very helpful for people who want to learn the patterns.

BTW, Choir's most likely impossible to beat without dodging with my skills, due to the RNG patterns and the high frequency of attacks on her third stage. I'll still give it a shot, but don't expect much :(
