In my mind, the competition is already over. Charlotte is unbeatable. The following is just the latest reason, and the one that cemented her victory.




Unfortunately, I fear that a Houki ending has become a foregone conclusion. Now that it has been discerned that Chifuyu is Ichika's type, there really can't be any other outcome. Despite being surrounded by all manner of other girls in various proportions, styles, and nationalities, it's clear that Ichika perfers raven-haired tall Japanese girls. That means his sister, and Houki. Houki also happens to be a childhood friend, which would normally work against her (reference: Fan), but she is the series ultra-tsundere now that Laura has turned full-on clingly/dere mode.

Lastly, Houki has had little-to-no development since the beginning of the series. That means most of the remaining episodes will likely focus on her. The girl given major character development last in a harem will be victorious.

It saddens me deeply, especially now that Charlotte displayed Akiko hairstyle, but she's still the second closest to Ichika, so maybe she can be the first of his mistresses.
