Tokki - The Bunny Vigilante

In a world where heroes are licensed, rated, a little pink thing refuses to follow the rules.

For nearly a year, the city's pro heroes have been chasing a mysterious teenage vigilante known only as Tokki - a sarcastic, glitter-bomb-throwing gremlin in a black-and-pink rabbit costume who moves faster than cameras can follow and vanishes before anyone can ask questions.

No identity. No records. No past. Just chaos, and sarcasm.

After eleven months of chasing, Tokki is finally captured.

The problem now is figuring out what to do with her.

The mysterious vigilante is sent to a rehabilitation program designed to understand her motives, uncover her identity, and hopefully guide her onto the right path.

Tokki may act like just a chaotic teenager...

...but someone with no past, no background, and skills that rival those of trained heroes doesn't just appear out of nowhere.
