Why did Gojo say this?? (Manga stuff)

Right. On previous cross-plays he had to work to hide a woman’s bust and hips. He immediately started thinking about how to do the opposite for a male. It’s all about the technical stuff with Gojo. It’s how he geeks out.

I also think this might lead to him working with male cross players in the future: foreshadowing maybe.

In ch 41, Gojo and Marin meets Himeno Amane or whatever his name is and he’s crossdressing, and Gojo said smth like “I’ve never worked on crossdressing” blah blah blah. But he has, when he worked with the Inui sister, right? Are the Inui sisters not on the manga or smth??
