自分 Was Taught: To Only Use a Real Katana in Battle
But later,: 自分 instead uses a blunt Bamboo Sword
Multi-Strike: Ignores causality & directly reaches the outcome, allowing 自分 to cut 相手 25x w/ 1 action.
Drawing: Sheaths & Unsheates his katana to strike w/ unassailable speed & power.
In the final clash, 自分 realizes 自分 doesn't have to follow the conventional path to swordsmanship, discsrding his Katana & taking hold of his bamboo sword in his waist, reaching a new level of swordsmanship.
