I wanna see Yomo meeting Touka and Ayato after Arata disappeared too! I think Yomo is the one who taught them how to fight. At least we know Touka used to train with him and the fact she asked Y if both her and K could go at him makes me think she used to go at him with Ayato too. Honestly a lot of things T did in the first part of TG had to do with Ayato one way or another. She missed him so much! That's why it is so cute to See Her fussing over him this chapter.
Yes! Touka mentioned sparring with Yomo- you’re right, I bet Ayato joined in too. I feel like they would have worked really well as a team… until it dissolves into bickering when they can’t get a hit on Yomo and “its your fault Ayato, if you weren’t so slow” “IM SLOW well what was that half assed kick back then, I’ve seen Grandmas with a better hit”
