"...I believe you. And I can see why you'd want to stay. This..." Kotetsu gestures at the garden around them, at the castle in general. "This place really isn't so bad. If I didn't have Kaede waiting for me, I might not even mind staying here so much." Of course, he also missed his brother, his mom, his friends...but Kaede, and now Barnaby, were all he really needed in life. The castle brought him here when Kotetsu was already leaving a familiar phase in his life, which was a kindness of a sort - albeit one he knew it hadn't necessarily extended to everyone.

"I'm trying to find a way home. But...I'll also try to find a way so you can stay. Okay?" This time, his smile is a little more genuine, and he even offers Asriel a thumbs-up. "We superheroes have to help everyone out, right?"
