The Refreshing Battle in Karuizawa! is the 15th episode of the anime series. During summer vacation, Haruhi gets a part-time job at a pension in Kuriazawa run by Isao "Misuzu" Sonoda, a cross-dressing friend of her father's. She hopes for a little peace and quiet sans the Host Club, but her dream is dashed when they arrive, unannounced. A contest erupts between all the hosts (except Kyoya) when they realize there is only one remaining room at the pension. Who will be the most "refreshing" in Misuzu's estimation and win the coveted room?
