Memetic Mutation: A Photoshopped image of a younger Tsukiko in episode 12 that turns the taxi she's sitting in into a cop car, making her literally jail bait.
Tsukiko fans and Azusa fans will never come to an agreement.
And at the end of episode 7, a new ship arrives to do combat in a three-way battle...
It looks like we will have a harem ending anyway. The whole light novel will end soon, and the relationship between Azusa and Tsukiko is currently just so good that they agree to share Youto equally. Not to mention Mai has confessed her love to Youto in volume 9 or so.
