A small or "chibi" version of Ryouko Asakura that is present in the Suzumiya Haruhi-chan no Yuuutsu 4komas.

In her form, she is sometimes chased by cats and would eat her, that is why Yuki took her in. At first, Achakura refused but later adapted to Yuki and became a maid-like chibi person working in Yuki's home.

She is sometimes tortured and frightened by Yuki.
