Leo and Luna's penthouse
Leo and Luna's parents are often away, leaving the penthouse all to Leo and Luna. While Yusei Fudo was on the run from Sector Security, the twins found him unconscious outside and brought him in, after Luna sensed something. They managed to talk Yusei into staying for some of the night. They also let Bolt Tanner and Tenzen Yanagi stay here while investigating the Dark Signers.
