Kotaro Yamaji was just your typical salaryman. Worn down by the stress of work, only finding solace in his hobbies as a closet otaku.
One night, as he's coming home from buying a snack, he gets transported to a place called the Crossworld Hotel. A place that exists between fantasy and reality. A place where those chosen could fulfill their desires to engage in erotic activities with any fictional character they want.
Meeting it's quirky manager Wendy, Kotaro can now spend his nights engage in his fantasies while building friendships with the other patrons all while learning about the history of the hotel and what it actually is.
