Having caught up on what I've forgotten, I have remembered why Haruna is my favourite character of this show. She's sweet and kind and adorable and for some reason I find myself rooting for her over Lala, even though Lala is supposed to be the primary female character.
Which does mean that I am rooting for Haruna to end up with Rito, despite Rito's generically clumsy nature as a harem comedy male protagonist. It's clear that Haruna does not mind, and perhaps indeed finds it endearing, but truth be told I'd also root for her to end up with Oshizu or something if the plot demands it, as long as Haruna is happy. That, and only that, is the primary criteria for this instance of To Love-Ru shipping.
In this case, Haruna's happiness trumps Lala's happiness, perhaps because Haruna doesn't seem to place a very high priority on her own happiness, thus requiring the fans to take up the slack. It's an interesting puzzle to contemplate: I don't feel as bad when I think about Haruna getting Rito and Lala losing out (assuming Rito doesn't go the harem route), whereas contemplating Haruna sad, regardless of who else Rito ends up with, is a terrible feeling. (Yes, I'm easily-influenced.)
There isn't even the question of whether Rito is Good Enough for Haruna. Haruna certainly thinks so, and apparently what Haruna says is good enough for me. Further examination of the matter starts to feel like I'm thinking too deeply into the whole business, and I may as well start working out the physical specs and ramifications of Lala's inventions rather than point out whether Rito's faults outweigh his good points in the overall success of Operation Make Haruna Happy.
And yet, I might be overthinking it anyway, since I'm actively rooting for a character in a harem comedy that does not have any form of resolution to date. Watching events conspire to prevent Rito and Haruna from getting together more than they have is… frustrating. There is the strange urge to reach into the screen and lock the two of them together in a room for however long it takes for either one to confess (or for teenage hormones to dictate the action, whichever comes first); Mikado-sensei can provide the facilities, and I'll even give them privacy. Just get together, dammit.
Of such feelings are fanfics born.
On a tangent, the nature of the series makes it understandably difficult to look for pictures of a remotely worksafe nature.
