|List of Characters|
Matoba Seiji (的場静司, Matoba Seiji) is the head of the Matoba clan and Natsume's enemy. He can see spirits, and throughout the series, refers to youkai as 'bait' and 'tools'.
Matoba has long black hair and black eyes. He has a smile, much like Natsume's, except Matoba has a more sinister atmosphere.
He has a scar over his right eye which is covered by a special eye-patch. The reason for this is: a previous head promised his right eye in return for the help given by a youkai, but broke the promise with that youkai and never handed over his right eye. Ever since then, the youkai has been targeting the male family members of Matoba head's right eye. Due to this, he has depth problems.
Matoba is a cold-hearted exorcist. Although he wants to protect the humans, he will not hesitate to get rid of anyone who gets in his way.
He will also readily sacrifice weaker youkai to lure stronger ones in for the catch. Natsume arouses his interest after one meeting, up to the point where he would save Natsume and Madara from being eaten, which is unusual of him. As the story progresses, Matoba seems to start liking Natsume and is seen smiling kindly at him. Matoba acknowledges Natsume's strength and even asks him to join the Matoba clan, promising to protect him if he does, however, Natsume refuses to. He also seems to believe Natsume and sends him a letter once, asking for cooperation.
Unfortunately, Natsume couldn't read it, though it would have been fairly interesting. Seiji himself says in manga : "I wrote an uncharacteristically long letter. Really, I wonder where on Earth it could have gotten to. But anyway, if you didn't read it, then that is that...perhaps this is a fate."
Judging from this, their relationship is slowly changing towards more open one, even though they still have a long way to go.
In the manga and anime, when he first appeared, Nyanko-sensei mentioned that he was some kind suspicious and sinister-aura person.
