Blade Steal

Blade Steal (, lit. "Imitation Sword Technique") is a martial arts technique utilized by Ikki Kurogane.

Description
Blade Steal is a martial arts technique, that allows the user to "steal" the opponent's swordsmanship. It was created by Ikki Kurogane, as he wasn't taught in swordsmanship, causing him to begin copying the techniques and styles of others. By using his great insight, Ikki can learn his opponent's swordsmanship and even improve on it. Additionally, after copying the opponent's style, Ikki can even use techniques that he hasn't seen. Thanks to this technique, Ikki has a great advantage against other swordsmen, as he can easily overcome their swordsmanship. Ikki has even shown the ability to copy techniques, that aren't originally swordsmanship techniques. However, the more skilled and honed the opponent's style is, the harder it is to copy it.
