To Love-Ru
Rito wins, everyone wins, everything pays off. I really really like Trouble. Darkness really hammered it home that Rito is basically a universe shattering reality warper whose suppressed lust for his imouto breaks causality and forces women to trip, fall, and land on his dick.
Neme-chan in full chibi sidekick mode made my dick diamonds for the entire last two story arcs. Momo is a fluid druid of the highest caliber. Mikan is basically the perfect wife who is saving herself for her big brother. Nana's cockteasing tsundere is flawlessly executed.
I know people like to shit on the entire genre, but Trouble is basically the way it is done right. It doesn't just give me boners in my dick, it also gives me boners in my heart.
