A piercing cry burst from within Casio's body, as if it could penetrate the skies with its shrill scream, carrying an unequaled ferocity and grandeur. Scarlet airflow swirled and churned, continually brushing past the corners of Casio's eyes. In his azure blue pupils, a red dot grew larger and more distinct. Finally, it transformed abruptly into a sinister Blood Vulture, lunging forth!

Its blood-red wingspan blocked out the sunlight as it dove through the air with the posture of a gliding predator, bursting the atmosphere around it.
