Mai 50 Waifu Harem:

The art of storytelling is mainly about the art of presenting admirable characters.  Japan has worked hard to churn out a great many admirable heroines over the years, in a wildly disproportionate number to the number of heroes, probably because they realize beautiful women of varying interests, abilities and personalities are just all around more interesting than 'badass' or 'stoic' men, really the only possible role a heroic male can ever play.

So many great women exist in fiction its hard to love them all properly, but luckily my heart is as wide as the Pacific Ocean, so I feel a genuine connection to not just one or two of these girls, but easily love all fifty as fervently as any man has ever loved a fleshy wife.  In fact, I suspect I find the girls of these stories more admirable and lovely than any man finds any woman in the real world -- that's just how great the gap is between our ability to imagine wonderful women and women's ability to actually be wonderful women.

I've already covered 40 of the top 50 women, so this is about filling in the remaining holes with the best available remainders from all corners of the Japanese entertainment world.  Who are the remaining ten women who deserve the utmost honor of becoming my brides?:

Cure Dream (Nozomi Yumehara) and Cure Lemonade (Urara Kasugano) from Yes Pretty Cure 5, Silica (Keiko Ayano) from SAO, Haruka Saigusa and Kudryavka Noumi/Strugatskaya from Little Busters!, Azusa Nakano from K-On!, Kagome Higurashi from Inuyasha, Aoba Suzukaze from New Game, Teletha Testarossa from Full Metal Panic!, and Mira Yurizaki from Dimension W.

All together that makes 50.  Now we just have to get all the names in one place in an easy to read fashion.  Together, they are the 2d Waifu Hall of Fame: (in no particular order, because I love them all as much as humanly possible)
