Vocaloid: To Love a Popstar

Once a long held dream among a group of friends finally becomes a reality, visiting Japan. Simple but sweet. While being in the country itself was a big part of it, they had an ulterior motive. See, this band of idiots were casual super-fans of the idol group taking the entertainment world by storm- Vocaloid. Somehow they managed to get tickets to a major concert, their biggest performance of the year. However, unbenounced to the boys, a rising street gang was looking for their entry to the big leagues, with their targets set on that same concert. Will the boys manage to avoid the plot these unseen foes have set in motion? Or will they get caught in the web and be dragged into some shady business, which could very well change the course of their very lives?
