[Silent Killing Technique]: You can cover the target's mouth so that it cannot make any sound.
"So silent?! Where is the killing technique!"
[Seven Arrows with Nail Heads]: When you nail seven arrows to the target's head, you can kill the target.
"If I can nail all seven arrows to his head, do I still need you?"
[Split action]: Your head has the ability to split into pieces. The separated parts can fly. If the distance from the body is too far, the part will be lost forever, which may lead to death.
"Good guy, it doesn't matter if you have a different body and a different body, this is the real separate operation."
