[Revealing Swordsmanship]: 自分's sword doesn't just cause pain—no, it makes 相手 remember them, opening old wounds & tearing 相手's body, effectively piercing through all of 相手's defences despite only using enough force to lift a single cup of water, but it's not just their body, but also bad habits that 自分's sword reveals.
Such is the divine technique 自分 has developed throughout his life.
