Jidanda

Jidanda is weapon that was created by Iou, using data that he collected from his previous creations, Dako, and Tsuru-Kame. It is a giant iron ball that contains exploding tags inside of it. Its handle, like Dako is able to stretch, and can even be used to attack the enemy. The spikes on the ball can open to reveal exploding tags for surprise attacks. Because it is so large exploding tags can be used to maneuver the ball into the air, using the recoil from the explosion. While in the air the weilder can extend the handle and swing the ball at the enemy.

After seeing Tenten use it in battle, Iou took Jidanda back from her to adjustments.
