Kōtatsu

was an ink painter who used the Shikon Jewel on his ink that contained his blood. He can summon a demon brigade using his paint art. This demon painting comes alive and is controlled by him. He used these demon paintings to destroy an army. He fell in love with a princess who ordered her guards to stop beating him. Kōtatsu was then thrown into a river.

The lord sent an army after Kōtatsu, who used his hell paintings to defeat them. Inuyasha killed some of the demons, and the rest were absorbed by Miroku. Kōtatsu summoned and rode a three-headed snake demon, but Inuyasha was able to slice the ink container, which contained the Jewel Shard. Without it, his snake demon was destroyed. Kōtatsu stabbed himself in the arm, telling his ink to take his blood and return to power. Instead the ink devoured his blood, destroying him.
