One of Shiki's main protagonists opposing the vampires.
Natsuno is a 15 year old boy who can't stand living in the town of Sotoba and the fawning of Megumi Shimizu. Despite his cold exterior, he does show care towards his close friend Tohru and shows concern for the well-being of the villagers when he becomes increasingly aware of the presence of vampires within the small town. With his increased activity towards trying to stop them, the vampires that serve the Kirishiki family try to kill him off by turning him into one of them. Toru finds himself forced into feeding onto the blood of Natsuno when he was turned into a vampire earlier on. However rather than a vampire, Toru's blood feeding leads Natsuno to turn into a werewolf who is still capable of living in the sunlight and doesn't need to feed on human blood in order to live. Rather than help out the vampires, Natsuno teams up with Dr. Ozaki to bring them down.
Natsuno's parents had Natsuno when they were still in college. They didn't marry because they didn't believe in the marriage
system. After living in the city for quite some time, his parents decide to move to Sotoba. His parents wanted to live more in nature, but Natsuno absolutely hated the small village. Natsuno is determined not to make any friends, because he will study for college and get out of Sotoba as fast as he can.
Natsuno and Megumi's eyes meet.
Natsuno and his best friend Tohru
This didn't go as planned as Natsuno quickly became friends with Tohru Mutou. He is also the only one to call Natsuno by his first name although he doesn't like it. He also befriended Tohru's siblings and nurse Ritsuko, whom Tohru has a crush on. Masao seems to hate Natsuno for some unknown reason. Megumi Shimizu is in love with Natsuno, but Natsuno doesn't love her back. As a matter of fact, Natsuno even seems to hate her. Megumi always admires Natsuno from the bushes near his window at night. Like Natsuno, Megumi also wants to leave Sotoba because she hates it there.
Natsuno still feels Megumi's presence
When Megumi dies of a mysterious illness, Natsuno doesn't seem to care one bit. He is actually quite relieved knowing that she won't be lurking from the bushes anymore. Kaori, Megumi's friend, offers him Megumi's late summer greeting card she never got to post. Natsuno refuses to accept. Some days later, Natsuno begins to hallucinate Megumi and still has the feeling she is somehow watching him. It's gotten so worse that he is not able to sleep at his own house any more and frequently spends the night at Tohru's house to get some sleep. However, without knowing, Tohru invites Tatsumi (one of the Kirishiki's) into his house and he allows him to bring a friend as well.
A terrified Natsuno notices Megumi
Some days later, when Natsuno once again has a sleepover, Natsuno has the feeling that someone is entering the house
and climbing the stairs. The door of Tohru's bedroom swings open revealing it to just be Tohru's younger sister Aoi. Relieved, Natsuno tries to go back to sleep but suddenly noticed MEGUMI staring at him from under Tohru's bed. A terrified Natsuno watches as Megumi attacks Tohru, because Natsuno likes him better than her. Suddenly Natsuno wakes up and checks on Tohru, who seems to be fine. Natsuno goes back to sleep, relieved that it was all a terrible nightmare. Or was it?
Tohru's sudden passing
Natsuno tears up Megumi's card
A few days later, when Natsuno wants to visit Tohru, he finds the doctor of the village is also visiting. When Natsuno and Tohru's siblings enter Tohru's room, he is pronounced dead by the doctor. Tohru wasn't feeling well the last few days, he was skipping school but told his parents not to worry because he figured he just had a summer cold. Natsuno is shocked by the death of his friend and conclude that Megumi's visit was not a dream.
Natsuno at Tohru's wake
Before going to Tohru's wake, Natsuno's mom hands him Megumi's late summer greeting card which they received in the mail. Natsuno tears it up and throws it out of the window. At the wake, Natsuno wishes to see Tohru's face and Tohru's father opens the coffin. Natsuno remembers all the good times he had with his friends and can't believe he's really gone. After the wake is over, Masao tries to argue with Natsuno because Natsuno didn't shed any tears at the wake and calls him heartless.
A few days later, Natsuno meets Akira Tanaka and his sister Kaori who are spying in the Kanemasa mansion and discovers that they too find the mansion highly suspicious. They decide to team up and dig up Megumi's grave to confirm that she's truly dead.

Natsuno isn't very pleased with his parents
While all this is going on, Tatsumi had noticed that Natsuno has become aware of the existence of vampires and wants him dead. So he sends a young vampire girl called Shizuka to his house to get an invite. Natsuno is not home and his parents answer the door. Shizuka acts very creepy for a pre-schooler but she manages to get an invite anyway, telling them she wants to wait for Natsuno in his room. When Natsuno arrives home, his parents inform him that he has a visitor, but Shizuka is already gone when Natsuno enters his room.
Not giving up that easily
Later that night, Natsuno hears a person roaming around his house, knocking against his window. Natsuno thinks its the guy he beat with the shuffle earlier and grabs a wrench in order to protect himself. The person tries to enter through the front door, which isn't locked because Natsuno's dad believes that you don't have to lock your doors when you live in a small village as Sotoba. But the person doesn't enter through the front door and instead walks back to Natsuno's bedroom window and knocks once more. When the person also calls Natsuno's name, Natsuno is shocked because he recognizes the way he is addressed and the voice...

After being attacked, Natsuno tells Kaori and Akira that they should leave Sotoba as fast as they can. He thinks the goal of the vampires is to turn everyone in the village into one of them. He puts them on a bus. The following night, Tohru doesn't come by to visit. But the next night he does, but Natsuno is ready for them. He ambushes Tohru with a crucifix and discovers that Tohru hasn't exactly changed, he is the same Tohru as before. Tohru explains that vampires need to kill to survive, to them it's the same as humans killing animals in order to live. Natsuno threatens Tohru with a stake but decides to run away. Tohru chases him and finally Natsuno decides to offer Tohru his blood but they should escape together. Tohru is too afraid if the consequences and bites Natsuno for a second time.
