The Stanta H.R. Building is a location in No More Heroes 2: Desperate Struggle. It appears to be the same building occupied by K-Entertainment in No More Heroes, although by the events of Desperate Struggle the building hosts the offices of the United Assassins Association (misspelt here as United Assassin Association) and K-Entertainment is not mentioned.
Sylvia Christel regularly makes calls to Travis Touchdown from the UAA offices throughout the game, as well as occasionally inviting him to the offices in person.
The building's nameplate lists several other companies based at the premises, including Motor THREAT co., ltd and JEF BEAFRA office, although their offices are not seen.
