Hinaichigo is the sixth doll and basically the embodiment of being a kid—childish and selfish, but genuinely well-meaning toward people she cares about. Her power doesn't really match her personality; she wields strawberry vine attacks that she mostly uses to pin opponents down rather than anything more brutal.
She loses the Alice Game to Shinku early on, becoming the first doll to get eliminated. The catch is that Shinku didn't actually beat her in a straight fight—Hinaichigo just drained her medium Tomoe's energy completely. When Shinku pointed out that continuing would literally kill Tomoe, Hinaichigo gave up the tie herself rather than risk that. In a surprisingly gracious move, Shinku didn't take her Rosa Mystica. Instead, Shinku let herself become an inter-medium so Hinaichigo could keep drawing power from Jun instead.
She's obsessed with strawberry daifuku (which she calls "unyuu"), and she's weirdly into Nori's "Hanamaru Hamburger"—a fried egg on top of a burger patty shaped like a flower. She also loves the puppet detective Kun Kun, though not nearly as intensely as Shinku does. Drawing is basically her thing; the anime shows her at it constantly.
Her speech pattern always ends sentences with "na no," which is her version of "that's why" or "because"—kind of the counterpart to Kanaria's "kashira."
In the anime, her singing and her bickering matches with Suiseiseki were actually improvised by the voice actors.
