I Was Told There Would Be Magic Sword-Busting!

I Was Told There Would Be Magic Sword-Busting! (魔剣破り、承る！), also called Anti-Swordsman, Anti-Swordsmaster Greater Bounded Field (対剣士・対剣豪大結界), is a "fantastic sword move" that Miyamoto Musashi is said to have been used only once during her long life as a swordsman. The only one who knows what the technique is like is Musashi, as none who have seen it have survived. It is a "special Saint Graph that mercilessly insults, disparages and crushes swordsmen who degrade themselves to sorcery, dark arts or heresy."
