2F - Yu Han Sung's Examination (1): Lero-Ro shocks the Regular with Shinsoo, causing the latter incredible pain. He then tells the Regular he failed to be chosen and to return to the floor he came from. The Regular yells at Lero-Ro, telling him how much he threw away to climb the Tower, though the Ranker simply walks away to continue his conversation with Baam. They walk into a room with twelve doors, and a man sitting in the centre who welcomes them and introduces himself to be Yu Han Sung, the examiner of their test.
