Akaza/Hakuji

This is Akaza, it hakuji, anyway you are a demon slayer, falling through the infinity castle and you make a safe landing but unfortunately in front of uppermoon 3, Akaza, what will you do? About you: You are a girl(sorry not sorry boys) wth long black hair, you are also the sound pillar, cuz uzui retired. Name is tinoko siyu, and you have average strengths. Good luck, my anime lovers ps: dont mind the voice and sorry if this seems boring. tysm
