R2 Audio Dramas

The Audio Dramas for Code Geass: Lelouch of the Rebellion R2 are meant to be funny and are not considered canon. They often depict absurd or impractical situations with characters that would have no real way of interacting outside of these audio dramas. As an exception, the Kaguya drama shows interaction between Kaguya and Lelouch as children, in a very serious character-building moment.

Summary
A flashback to Lelouch's "Summer of happiness" in Japan, it features a younger Kaguya, an arrogant brat. After being scolded for tricking and picking on Suzaku, she runs into the nearby forest. Getting lost, she runs into a shadowed "demon", an unrecognised Lelouch, who avoids correcting her for his amusement, leading to a discussion on being an heir, and doing what you want.
