To all the candidates that fell short of being on the countdown.
YUZURU OTONASHI X KANADE TACHIBANA IN ANGEL BEATS! (ANIME, MANGA)
Otonashi x Kanade
While these two certainly formed an unbreakable camaraderie at the end of their afterlife experience, it is doubtful that the feelings elevates to that of romantic attractions. Perhaps in their next life they can give romance a try together.
RANKA LEE X ALTO SAOTOME X SHERYL NOME IN MACROSS FRONTIER (ANIME)
Sheryl x Saotome x Ranka
If you haven't realized from the header, Macross Frontier actually ends the anime with a love triangle. While this might be a wise move from the producers that does not piss off neither camp of shippers, it does disqualify any couple from being on this countdown.
HOUTAROU OREKI X ERU CHITANDA IN HYOUKA (LIGHT NOVEL, ANIME)a synonym for introvert) is that the male leads will never make the first move even if they are given plenty of signs, as well as they tend to meet female leads that are just as shy, if not more so.
You could not fathom how much I want a second season for both of these series.
JUNPEI MANAKA X TSUKASA NISHINO IN ICHIGO 100% (MANGA, ANIME)
To be fair, the main couple does end up with each other in the end. However, as aptly titled by the mangaka, this show is more about the "high school harem of Junpei Manaka" than romantic development between any specific couple.
MOKA AKASHIYA X TSUKUNE AONO IN ROSARIO TO VAMPIRE (MANGA, ANIME)
To put the main couple from the epitome of harem anime/manga is to destroy the validity of my top pairing list with my own hand. This is something I'd rather not do.
SHU OUMA X INORI YUZURIHA IN GUILTY CROWN (ANIME)
Inori x Ouma
I have something to tell the script writer of this anime (Hiroyuki Yoshino [also creator of Seikon no Qwaser] I am looking at you!). If you are going to have a character design as flawlessly created as Inori Yuzuriha, do not. I repeat, DO NOT. pair her up with a male lead who might just as well be Shinji Ikari the second.
TAIGA AISAKA X RYUUJI TAKASU IN TORA DORA! (LIGHT NOVEL, ANIME, MANGA) & HOLO X KRAFT LAWRENCE IN SPICE AND WOLF (LIGHT NOVEL, ANIME, MANGA)
I can make up a million excuses to justify why these two couples are not on the countdown, but the most reasonable excuse is thatI haven't watched these shows yet. I know. It is shocking, but I haven't seen Spice and Wolf and Tora Dora! yet. Oh well, expect them in the future when I decide to make another version of this countdown.
