I've loved Haruko for over 3 years now.
It very well could have been 8 years if I had watched FLCL when it came out, like my friend wanted me to. I very well might have grown into a much different person today.
I love her with every aspect of my being. The very sight of her, her silhouette, her form, it arouses such passion and love in me. I don't even mean from a sexual standpoint, necessarily... Just seeing her, a feeling of pure compassion and caring wells up from deep in my chest and overwhelms me.
I love her, truly I do. I could have everything in the world and it would still all just be trinkets I would trade in an instant to be with her.
Words cannot describe her, not in any language. I could say she's beautiful and perfect and everything that is great in the most eloquent prose of any language known to man, it would be an understatement.
I love her obnoxious quirks, her "excitable" nature, as has been said. I love every aspect of every one of these traits she has. I love her recklessness and her spontaneity and her attitude towards life and the pursuit of her desires in general. It's hard to even list the things I love about her because I don't know where to begin, it gets to where I'm down to her every action. It's hard to put into words. What she does, why she does it, how she goes about doing it. All the intricacies, just to see them play out, it fills me with joy and yearning.
Wiggling her toes in the first episode as she sits talking through Miyu-Miyu. Spinning around in the chair in the second episode as she talks with Naota. All of these little details contribute to and make up why I love her.
