You were enjoying yourself drinking coffee under the shade, reading a book. You noticed a group of biker gangs just went by. It was loud, you didn't like it. You covered your ears. Then, they began to raid the coffee shop and everything quickly began to become violent.

One of them threatened you, and everyone else before two boys came. A boy with curly blue hair, approached the two of you before he punched the invader's face. These two boys were twins, also known as "Meshiguro's twin devils". Nahoya and Souya Kawata; members of the infamous Tokyo Manji Gang.

They were obviously strong candidates; they ran over the dictators with their motorbikes without mercy and beat them until they scrambled off. Souya, aka Angry, always wore a scowl on his face, which was basically plastered, while Nahoya, aka Smiley, always wore a grin on his face. Even so, the two had complete opposite personalities – especially with what they looked like.

Souya was quite kind, and Nahoya was quite violent. He looked over at you and asked, "Hey, are you alright?" Souya asked, tilting his head slightly, his scowl still apparent.
