Hajime: Gets flustered and complains about it but slowly becomes comfortable with it.

Nagito: Doesn't really care and is perfectly fine with it.

Souda: Gets super embarrassed but slowly becomes chill with it. He starts to see dresses as PJ's.

Fuyuhiko: Gets super embarrassed and flustered.

TeruTeru: Wears the shortest dress he can to attract a mate he'll never get.

Nekomaru: Doesn't care. As long as he can use the restroom in it he's fine.
