Ryuuichi is back from his trip to the east, but he seems under the weather. He's moody and introverted, very unlike the glamorous Ryuuichi we know and love. It's almost like his personality is flipped. While that's happening, a string of murders are turning the streets of London red. Will Ryuuichi be able to escape his slump and capture this menace or will we find out something about Ryuuichi that we can never come back from?
