Thunder Tooth

Description
Previously the sword of the Zombie Hero called Thunder Lasting. Once Lee Shin Woo armed himself with it it turned to bone, downgrading a level and changing form.

After evolving into Thunder Tooth:

The blade consisted of a bone gleaming in blue light, and was longer, and sharper than before; the fact that there was a slight power of lightning within had surfaced, and began to spark.
