Natori Shuuichi is the head of the Natori clan and Natsume's "friend". He can also see spirits. On the surface, he works as an actor, but his real job is being an exorcist. He is voiced by Akira Ishida.
Appearance
He has short blonde hair, a medium build, and red eyes. He has a lizard birthmark which is actually a youkai that moves around on his body. It can only be seen by people or spirits with strong spiritual power. It is his signature feature.
Roses and background light appear when he smiles, representing the fact that he's handsome.
Personality
Because he is an exorcist and has strong spiritual power, he has the ability to manipulate paper dolls (Shikigami) and has three spirits under his command. One of them, Hiiragi, was a youkai that he saved.
When Natori is first introduced, he hated spirits because of his horrible childhood. Due to this, he had a tendency of being harsh with the spirits. Natsume tends to disapprove of his forceful exorcism methods. But, after meeting Natsume, he gradually softens even though his ways aren't much different. Over the course, Natori develop concern for Natsume's well-being for he tends to be reckless when it involves with spirits.
His relationship with Nyanko-sensei/Madara was not very affectionate in the start, but he gradually becomes friendly towards him, almost as if Natori was Natsume and he was playing with him.
Also, because of the necessities of his work, Natori can lie easily. He knows that Natsume is of the same nature, he feels that he has similarities with him. This causes Natori to slowly become attached with Natsume.
