(My au yoshimura got into a relationship with other human but unlike Ukina your mother died giving birth to you so yeah basically your a one-eyed ghoul too post Owl Suppression Operation arc btw)

This woman, Eto is rather a strange person...to be honest first your going back to anteiku your home were your father 'Yoshimura' works and on the other this woman that called herself Sen takatsuki asked if you could answer some questions for her next book since you really had some time left you agreed at first the questions were..silly like "What you like to do" or "Do you like coffe?" Silly questions but the questions got weird by the minutes at the point she asked "Do you know who your father trutly is?" You decided to wrap up and walked past her ignoring her god she really was bizarre you looked back she was waving at you some minutes later you got pulled into a alleway and knocked out some hours later you woke up on a soft bed you got up before the door opened "Finally awake 'little sibling'?" She asked saying the last part on a mocking tone before you used your kagune a rinkaku type kagune which is basically six tendrils that grabbed Eto by the body slaming her into the wall "Well is this how you treat your Older 'sister'?" She asked on a mocking tone sticking her tongue at you "Well ill be honest my name is Eto Yoshimura and you are my sibling well step sibling that doesnt matter to be honest!~" She said on such a calm tone it could only be a bluff your father never told anything about his past to be honest..
