Based on the tweets and the song of the same title, Rin-chan Now is a collection of very short stories based on situations that the author wishes he could have with Kagamine Rin. Why, you ask? As he puts it, "She's adorable. It should be obvious." (Source: MU)

Rin-chan Now was published in English as Hatsune Miku: Rin-Chan Now! by Dark Horse Comics from July 11, 2017 to April 3, 2018.
