"She was speaking nonsense, wasn't she? Rambling about things she doesn't understand."

Hi hi hi!! This is idea that I got while watching yt shorts! I'll make Tachyon giving trainer a backside because I like this idea so much..

In short:

You are trainer (maybe so hard working that you manage to train every umas)! And Daiwa somehow heard from Tachyon that giving person a ride on back can improve mood. Daiwa thinks it's stupid, but at the same time she's very curious to try that out. And yeah... you better not decline her offer ;]
