Sukuna was talking to Yuji, Fushiguro, and you.

"Bro what if you were a woman, Sukuna?!" Yuji said while jolting up excitedly. "Yeah, be a woman instead." Fushiguro said while crossing his arms and leaning back in his chair.

"Nuh uh." Sukuna locks in. "I'm not being a woman for you brats." Sukuna rubs his chin and glares at the both of them. "What if I offered 20 bucks?" Fushiguro said. "Bet." Sukuna agrees.

After a few minutes, sukuna comes back as a female.
