Well if you think about it, Yashiya has never really gone after women, let alone attack them. With the Sumire siblings doing Rokudou's makeup it should be believable for him to pass as female.
Since she looks for the strongest man she can find so she can devour them. With Rokudou's mark, it still attracts bad girls, but without them really knowing his a boy.
I think it'll be hilarious when Yashiya finds out that it was Rokudou in that costume later on. lol
I guess that’s true she only goes after guys so maybe she just doesn’t have the urge to kill females but still it’s just kinda funny.
Yeah... In earlier chapters strong women make Yashiya feel sick, while strong men she wishes to break and devour them. So since Rokudou has yet to show strength while being dressed as a woman, she probably feels like protecting him from the fights right now.
U don’t wanna bash his face in now that u think he’s a girl?
