Enter the Five Ring of Niten Ichi ryu

This is inspire by the great Japan samurai Miyamoto Musashi, the book of five ring & the movement of ink splash.
From wikipedia: Niten Ichi-ryū (二天一流^?), which can be loosely translated as "the school of the strategy of two heavens as one", is a koryū (ancient school), transmitting a style of classical Japanese swordsmanship conceived by the warrior Miyamoto Musashi. Hyōhō Niten Ichi-ryū is mainly known for the two-sword—katana and wakizashi—kenjutsu techniques Musashi called Niten Ichi (二天一, "two heavens as one") or Nitō Ichi (二刀一, "two swords as one").
