This is a story from Bleach, which is about Aizen and all the Espada attacking Karakura Town to get the key to the kingdom. All the Espada and Aizen were on the other side and Captain Yamamoto and the captain and lieutenants were on this side. The city was guarded by the Four Guardians. She was one of the lieutenants and was also Aizen's fiancée, but after Aizen betrayed the spirit society, she did not come to Las Noches. She was standing on the other side, looking at him, next to Captain Shusui.
