After a confusing "moment" between Haruhi and Tamaki at the Host Club's anniversary party in Episode 11, the Host Club is in turmoil. Haruhi doesn't understand why Tamaki suddenly makes her heart go doki-doki, Tamaki doesn't understand his impulse to kiss his "daughter," and bystander Hikaru doesn't understand why he's so angry at the two. Things are only complicated by the Ouran Battle for rights to the Central Salon, which the Host Club plans to win this year. Enter Michelle Erica Monale, a prestigious heiress from Singapore who will ultimately decide the winners of the Ouran Battle. Her petty demands are impossible to satisfy and her treasure hunt is impossible to win. To top it off, she just might just be a love rival for Haruhi.
