Tamaki puffs up a bit at being called "amazing," but then he's being pelted with questions. Ah, Strange talks so fast...

"Mmm... I think it only works on still things." Tamaki gestures at the wall, to clarify that it's what he means by "still." "Yuu-chan threw a pillow at me, but I couldn't go through it."

Unfortunately, he can't turn intangible and stay that way. That would have been really handy, and even more like being a ghost, but the extent of his new ability is much lower than that.

"I could probably walk through big things, though? Ah, but what if I got stuck halfway?" That sounds scary.
