Indigo Secret Technique: Genocide Bomber

Name Of The Jutsu:
Indigo Secret Technique: Genocide Bomber

Describe what this jutsu does:
What this involves is that the puppet turns itself upside-down and starts spinning quickly on top of its head. While it's spinning, it shoots the explosives from both hands and both toes with short delays between each other, as if it was using a Gatling Gun. The technique covers a wide area due to the extremely short delays of the explosives and the high speeds that the puppet spins at. Puppeteers using this technique should be aware of this, and should try to either find a safe spot or defend, or else they'll be hit by their own technique. Sadly, opponents can do that too. But the angle in which the legs and arms are positioned can be changed while using the Jutsu, so the explosives can cover almost any direction.

What does it require:
To do this Jutsu, you need a puppet that can shoot missiles, bombs, or any kind of explosive round. You'll also need the proper ammo. Experienced puppeteers could use compressed chakra as a substitute.

What rank do you think it should be:
D-Rank, if using ammo, or B/A-Rank, if using chakra.

Personally I would approve this as d rank because your not really using much chakra but if you use your chakra and compress it so it explodes when launched out of your puppet it will take up the majority of your chairs during that fight but its still possible. But for this jutsu I'd say its d rank without the chairs thing. You just have to buy the supplies at the shoo which I'll put there now. It will be 50 ryo for enough supplies to use the jutsu once and you will get enough to start of with for free to use the jutsu once.
