So far he's been seen near a very long object covered in cloth, similar to Yamashita's staff or Zenmaru's Sadanaga, implying to be either a polearm, a staff or a large sword. However its true nature is still unknown and likely will never be revealed. He also used a shortsword to behead Tsukikage.
Intelligence: Average, combat genius
Jinkuu is a capable martial artist as he was strong enough to become one of the members of the leader's personal corps. His greatest skill seems to be ninjutsu, as he was tasked with killing Tsukikage along with Tsuchiryuu. Another testament to his power, is the fact that he managed to reach Tsukikage's hideout by taking down all the soldiers around it.
