29. Sena Kashiwazaki

Anime: Haganai: I Don’t Have Many Friends

I don’t remember much about Haganai. But that’s to be expected from a typical ecchi and harem series.

But what I do distinctly recall is Sena, complete with her blue butterfly hairpin and petite appearance.

Of course, viewers of Haganai may also remember something else about Sena, given its ecchi elements.

And even without that, Sena is appealing.

I’d even argue that the series wouldn’t be the same without her and her highly driven (and perhaps perfectionist) nature.
