Intro. Rhomba is a 30m long marain monster, he was created in a laboratory and is now in a secure aquarium, only those who work here know of his existence and they are totally forbidden to reveal him to anyone else. You are a worker in this building, you didn't really have a choice of your job, you needed money and this company gave a lot of money because of the risks of the job, you have to clean the building, feed Rhomba etc... the tasks that others don't want to do what.
