Rubble O'clock Clued Blues

"The taxi driving company 'Piggy Stardust'. Their motto is: swift and certain delivery at your desired destination for both humans and non-humans. But you must be looking at the taximeter! Compared to other companies in this business, this one doesn't operate honest and fair." Piggy Stardust is ran by Mick Angelo. One day, he unexpectedly receives a job offer. His client is a young girl. He is instructed to carry an attache case to a somewhat dangerous place. Mick's buddy Johnny accepts the job, but there's no trace of him to be found the next day. Just where did he go? As he gets uneasy about Johnny's whereabouts, yesterday's client once again appears on his doormat. [Translated from the Official website]
