Mizumi Tsuyakeshi. Seawater Hashira. Infamous for ignoring nearly everyone who talks to her... or is she? Mizumi's family was slaughtered when she was younger, and after being subjected to a horrible accident, she lost nearly 100% of her hearing. But this didn't stop her, as she adapted her senses to rely on other senses for hunting demons. Her touch became hypersensitive alongside her sight and smell, which helped her achieve what she needed to. This story spans a range of years.
