"Wyba, I don't want to get angry, but even after all that I said, I am still in the same position, this perverted sister doesn't care about my feelings. Right, I should just take an adult form, I am sure that this pervert will release me then."
Yale had no chances to win in a normal battle, so even if he had his legs free and could try to kick Aiwai, he didn't even think about it. Instead, he wanted to threaten her with his transformation; a mental battle was his only chance.
"Stop, don't do that. We can talk. I can't give up to have a bath with you, having a family bath with my cute little brother is something I always wanted to do, but I can negotiate anything else!"
Yale really hit in Aiwai's weak spot, she couldn't control Yale's transformation, and she didn't want that he changed his form.
