Summary and Preview
Imaginary Friends are creatures born from the imaginations of children. In this world, they physically exist. As the children who created them grow up, the Imaginary Friends move into careers of their own, while still cherishing their bond to their particular child. Kodachi Rurika and her Imaginary Friend are something of an unusual case. She created her Imaginary Friend at the age of 5, and it abandoned her by the age of 6. She barely remembers anything at all about her lost friend.
Rurika has now gone to art college in Tokyo along with her photographer friend Mizuki. College is full of challenges for Rurika, as she gets to know her artsy classmates and attempts desperately to impress her teachers with her drawings. But another challenge comes in the form of her long lost Imaginary Friend, Usa-chan. Usa-chan is a selfish, violent, slovenly bunny-girl, who is nothing at all like the quiet, polite Rurika. When Usa-chan moves in with her, Rurika doesn't understand how someone so different could have been born from her thoughts. In the process of getting to know Usa-chan, Rurika may end up gaining a deeper understanding of herself as well.
