These four friends couldn't be more different: Natsuki Hashiba, a dreamer who longs for love, Tomoya Matsunaga, a self-centered playboy, Keiichi Katakura, a winsome guy with a hidden saucy streak, and Tsuyoshi Naoe, a socially awkward nerd who loves anime, manga, and games. Together their high school days are as vibrant as rainbows!

Tsuyoshi is busy trying to finish drawing his manga before a big summer convention, so Natsuki, Mattsun, and Keiichi go to his house for the night to help. Will Tsuyoshi make the deadline, or will his three friends just cause more chaos for him?!
