Bro three sword style might seem cool but in combat it is inefficient because of head placement and shock from collision which affects the senses and eyesight which could be deadly don't try that again please it's better to focus on 1 sword just upgrade 2 sword style to sword master and fuse yin yang blades.
I suggest using sun breathing style and moon breathing style from demon slayer it matches the yin and yang blades and when you're ready to fuse the yin and yang blades you can do the same for the breathing styles and create: Sun and Moon breathing style, Chaos breathing style or Celestial breathing style pick your poison.
