Manga vs. Anime

 * His name was not revealed in the anime.

He discovered that his paintings would come to life after dowsing the shard in ink.
 * In the manga, he was beaten up by the lord's vassals for spying on the princess.

 * In the manga, he begged Inuyasha to spare his life and offered to give him his ink pod that contained the jewel shard. This was a trick to lower Inuyasha's guard so his snake yōkai could attack him while he escaped. In the anime, Inuyasha cut the ink pod from his waist and destroyed to pod.
 * In the manga, Kōtatsu's ink devoured him of its own accord, and he begged Inuyasha to save him before he was completely absorbed by the ink. In the anime, he willingly offered his blood to the ink in the hopes of fusing with it before he realized that the ink was devouring him.
