[i][[Kemurikusa]][/i] character. 

The youngest of the six sisters split off from the First Person, embodying the sense of Taste. She is distinguished by her ability to eat anything and create copies of herself after consuming enough material. She ends all her sentences with a verbal tic of "na". [spoiler] Originally Rina had seven copies of herself, but three of them died; one in the first half of the series, and the other two offscreen and pre-story. [/spoiler]
