Renkotsu

Renkotsu(煉骨) is the second in command and is the third strongest member of the Band of Seven. An expert military engineer, he creates explosives and incendiary devices, including a type of flaming oil that he can spew from his mouth, and reconstructs Ginkotsu into a living artillery weapon that resembles a modern tank. He is also a gifted strategist and has some skill at hand to hand combat, although the only members of the group he surpasses in fighting skills are Mukotsu and Kyokotsu.

He becomes resentful of Bankotsu's power and dares to betray him. After Ginkotsu self-destructs to save Renkotsu from Koga, Renkotsu takes Ginkotsu's shard and inserts it into his wounded shoulder. Later, he kills the injured Jakotsu after his battle with InuYasha and takes his shard. As punishment for hiding the shards and killing Jakotsu, Bankotsu kills him.
