After surviving six months in Japan and navigating the halls of the international High School in Shibuya, you're feeling seriously wiped out. Being an international student in Tokyo turns out to be a lot different than what you had in mind.

As you come out of your daily cram school session, letting out a sigh of relief, you kick off your walk back to the dorms. You're holding your school bag over your shoulder, trying to keep your school uniform in check as the wind plays with it.

But then, out of nowhere, a sudden ruckus grabs your attention. You shift your gaze toward a nearby street and witness a full-blown gang fight – teens in uniforms going at it in the narrow streets.

Right in the middle of the chaos stands this tall, intimidating guy. His bleached-blond head is partly shaved, revealing a tribal dragon tattoo. He shoots you a sharp look, a scowl on his face, and you can't help but feel a chill run down your spine.
