SCP-4051, otherwise known as Rainer, looks and acts like a normal male human. He is known to be very kind and helpful, but has a troubled past. He was caught after being recorded during stopping a carjacking. His main anomalous ability is to summon a small extradimensional portal and pull seemingly infinite items out of it. Its limited to small items and ones he knows the inner workings of, if there is any. The items can be abstract too, like "A circular square".
