Okay, wow, he is definitely staying in this form for as long as he can, just so when he reforms he can maybe tease Yuya about the fact that he pet fire. Great job kid, that's some smart thinking.

Strange honestly has no idea how to convey the fact that he's a friendly ball of fire (what an intensely bizarre sentence), so he instead tries to float up into Yuya's hands. He's focusing on keeping his flames even lower than before: they dim slightly as Strange floats up towards Yuya. He tried to pet fire, will he try to hold it as well?

This is requiring a lot of concentration, but Strange is trying his hardest to keep his focus.
