Natsuno Yuuki Husbando

Natsuno Yuuki (or Natsuno Koide) is one of the main protagonists of Shiki. Originally a city dweller, he reluctantly moved to Sotoba with his parents. His father's surname is Yuuki. However, his parents did not get married and he has his mother's surname. This makes his legal surname "Koide"; not "Yuuki", as some might assume. Natsuno is a calm and highly intelligent individual, and he is often seen studying in his room. At first glance, he comes off as cold, quiet and uncaring, especially towards Megumi. However, he shows throughout the series that he is very caring of those he considers his friends, such as Tooru, Akira and Kaori.
