There are the techniques used by the Rurouni Kenshin characters:

Amakakeru Ryuu No Hirameki
Part Two of the Hiten Mitsurugi Ryuu's Succession Technique; a Battou Jutsu stances that leads with the left leg. Only those who have the will to live can learn this technique. The attacker will attack as normal, and the user will use the Ama Kakeru Ryuu no Hirameki to defend and counterattack. To acquire it, the inheritor must defend from his master's Kuzu Ryu Sen. The technique is so powerful that usually, masters of the Hiten Mitsurugi Ryuu die when teaching their students.
