Found out that Akretto (Grassland) ID 131 could also hit 43 on crit, so using this instead. It's "only" 123 frames faster than the Kaya WIP however, so there's still 200+ frames of waiting viewers must endure.

Recruits Cotta with Kaya as ally. I'm not pursuing using Kaya however, because even though it deals 43 damage to Ryuuguu, it takes 300 frames of waiting + ~300 more frames of detour for a stat boosting item to 2 turn KO Ryuuguu. Uploading for now in case that ends up faster.
