Role in the storyEdit
Canon to GCBKEdit
She and the other hanzo girls found themsleves in GCBK, and Asuka went to the Divine Butterfly place.
They meet the royals for the first time and ask why is everything so different. Seitekina says that "Entering the GCBK will result in change.". Katsuragi had groped Asuka from behind much to Asuka's shock and disgust. Seitekina appeared to not apporove of such reaction and looked at her directly.
In Arc II, Asuka and her friends are introduced into the story. At some point, she befriended Seitekina and became good friends with him.
She was married to Seitekina during the Senran Kagura Breeding Chain, at the date of September 8.
