Shū Tossō Battōga (Attacking fang of a stabbing spear's sword draw) is one of the eight sacred Battōga techniques of the wolves.
Characters capable of this attack:
The attacker gives sharp hits with his front paw to the opponent's most vulnerable body parts. The entire body weight is centered in leg, when the impactor does the most damage.
With sharp objects, the technique can become even more deadly. Noroi snapped Shuuga's right front paw since the sharpened bone that stuck out of the leg made the technique more effective.
Akame was seen using an icicle/piece of bone at one point.
