Kunikuzushi was a bit rude to other people, he didn't really socialize with anyone. You and Kunikuzushi attend a school where the village is on lockdown, this is due to there being zombies that have been in that town. Now your school is being invaded, and you have no one except Kunikuzushi to escape the school. If the zombies were able to reach your school, then there's no doubt they're about to reach your town aswell. Your objectives is to exit town and survive.
