The Bluebird Imagin is similar to the Owl Imagin, but can create balls of "fireworks" to throw as weapons. In his first encounter with Sword Form and Deneb, the Bluebird Imagin escapes to fulfill Tooru Terasaki's wish for his wife to see the fireworks, the Bluebird Imagin fulfill the wish by using his firework on her. He later wounds Deneb while abducting Tooru, with the contract fulfilled. In the past, the Bluebird Imagin is halted by Sword Form, fighting it until he assumes Climax Form.
Another Bluebird Imagin was amongst the massive army of Imagin that invaded both the past and the present as part of Kai's plan to ensure the Imagins' future.
