Lilly

Lilly is a minor character in ImA. She (like Kitti) belongs to the few female characters in ImA who have a more serious personality (in contrast to cheerful characters such as Yuuna and Jean). She is canonically bisexual.

In Season 2, she becomes a more important character. It turns out she is a villain (maybe the main villain of Season 2?) and in a relationship with Daini. She also turns out to be the same person as Tetsuko, the latter being her disguise when she's working with Naoki.

One of the things Lilly did was hurt Odie, Kitti's dog.
