The surprise attack on Seireitei had all thirteen squads up in arms. Nana tried to keep calm as she slashed away at the hollows that kept closing in on her. She caught a glimpse of Matsumoto, who was in the same situation as she was, and she saw Hisagi running to Matsumoto's aid.
Nana felt her heart drop and, in that moment of weakness, a hollow took the chance to stab Nana's side while another slashed at her back. She felt her body falling and she wondered if she would die with a thousand regrets.
