Yes, I think this is canon! isn’t Kaneki said to smell like a female ghoul in the original TG, because he has Rize’s kakuhou? 

For those reading, in this scenario, Tatara is trans.

“I never expected someone so tall to be a girl,” says Torso, glancing up and down Tatara. 

“I’m not,” Tatara says, keeping his usual icy demeanor.

As soon as Tatara leaves the room, Eto drifts over to their newest recruit. 

“Hi there, Misogynist,” she purrs in his ear, leaping up to drape an arm over his shoulder. “Let’s not add transphobia to the list of your misdeeds.”

“I didn’t…”

“Look, you’ve heard us use male pronouns for Tatara. You mess up Tatara’s gender again, I’ll eat you,” Eto says, punctuating with a giggle. “Get it?”

“Uh – yes, of course!” Torso stammers, sweating.

“Good.” Eto slinks away. “I’m looking forward to your better behavior.”
