Sirica is a major character in the Kirby anime series Kirby: Right Back at Ya!.
In the Kirby: Right Back at Ya! anime series, her mother, Garlude, teamed up with Meta Knight to get Galaxia. Garlude was accidentally killed, so Sirica wanted to get revenge on Meta Knight because she didn't know the truth. After her sword told her the truth, she became friends with Meta Knight and Kirby.
She later joined forces with Kirby and his friends to defeat Meta Knightmare. Sirica later teamed up with Kirby again to defeat the Hydra that was terrorizing Pop Star, and also accompanied Kirby in his quest to go to the end of the universe to defeat the ultimate evil. In the final battle, she is apparently destroyed along with Meta Knightmare after the final boss exploded, but it is eventually revealed that Meta Knightmare created a forcefield at the last moment and saved both him and Sirica.
Sirica's final appearance is in the ending scene, where she, Kirby and all the other characters are having a party, in which she is having some cake along with Meta Knightmare (who took off his suit for the party).
