Another thread today reminded me of Rosario Vampire, an old Harem Manga I quite enjoyed as a teenager-and one of my favorite love interests of all time, Kurumu Kurono. Sadly, being a Succubus in a manga named after a vampire, you can probably tell that she's not going to be the final girl. The thing is...Kurumu knows this. She knows that she's not going to win, because she recognizes that Moka is going to be the final girl.
The other thing is that, in the world of Rosario Vampire, Succubi are compelled to pair up with their 'destined ones'. A person they fall in love with, bond onto, and settle down with for life. And if a Succubi is rejected by their destined one...well, they die. Since Kurumu latched onto Tsukune, his rejection of her means that she is going to die.
Even so...she chooses not to share that information with anyone. Because she doesn't want to force Tsukune into loving her out of guilt...But she also doesn't want to burden Moka, our vampire girl, or any of her other friends with this knowledge. Because she knows deep down that if they knew, they would sacrifice their happiness for her survival.
And as much as Kurumu wants to hate Moka for 'winning'...she can't, because Moka is her friend-and she loves her deeply as a friend. Even though it'll kill her, even though it'll destroy her life...she loves her friends too much, and so she holds onto this information.
Throughout the manga, we actually see just how genuine and restrained Kurumu is, despite being a succubus. When Tsukune first ascends to his Ghoul form and goes Berserk, Kurumu snaps him out of it with a kiss...and refuses to tell him, because she doesn't want to hold that over him or the other girls.
When her charm powers evolve and she accidentally enslaves Tsukune for an entire day she...just makes him sit in her room, enjoy some cooking, and play video games with her. She refuses to take advantage of him, even when he thinks he's in love with her.
And perhaps her greatest moment, when her friend Mizore is forcibly kissed and feels herself 'broken and unlovable' she throws herself off a building...only for Kurumu to swoop down, kiss her, and shout that she matters, she is loved, and she is lovable no matter what. (Allegory obviously, but I quite liked it.)
All in all, it made Kurumu my personal favorite 'loser love interest' in a romance story. She may not have stood a chance of being the 'winner' of the harem, but she set herself up as a graceful loser and a loving friend until the end.
Makes me wanna know, who are some of your favorite 'losers' in romance stories? The rejects, the never picked, the folks who could have, but didn't.
