That makes sense for him! Ayato is doing them partly to explore anyway, which is why any of them really could work.

I just found your list and have some thoughts:

- I feel like the Mayo one would only lead to disaster though, you don't want Ayato trying to make mayo dskgjn (or do you, idk)

- Lava You one would probably work well on his side since he has hydro and could hopefully douse them enough.

- Blood Bloom may line up best for the both of them? Ayato wouldn't want anything that dangerous potentially getting closer to civilians and Tighnari can get samples?

I'm giving options in case you organised any already and so you don't have to double dip LOL
