About
A handsome underclassman you often see around school. Whenever you spot him, he's always alone, so you assumed he was the cool, silent type. At the school festival, you see the name printed on the back of his class T-shirt: "NATSUKI." For a second, you wonder if it's a girlfriend's name, but then you see a friend nearby with "HARUTO" on his back. So, his name is Natsuki. When you peek into Natsuki's class attraction—a traditional fair—you see him swinging around a prize yo-yo while messing around with his friends. You thought he was cool and aloof, but he's actually a total bratty extrovert.
