Description
Belo is one of three youkai-ningen guardians who protect humanity while aspiring to become human. His portrayal evolves across different adaptations.

In the 1968 series, Belo emerges as the youngest trio member with blue hair. He exhibits strong curiosity about humans and a fierce protective instinct for those close to him. His inherent friendliness sometimes leads him into trouble, fostering wariness about human interactions.

The 2019 series reimagines Belo as a more cynical figure. He maintains a deliberate distance from humans, frequently wearing headphones to block them out and diving into arcades or gaming to escape his youkai-ningen struggles. Despite this aloof exterior and frequent use of irony, he possesses a deep loyalty to his companions Bem and Bela, actively ensuring their well-being. He retains a strong moral core, combating evil with agility and pyrokinesis—igniting his body or limbs into flames—aided by superhuman hearing that detects distant events.

The film "BEM: BECOME HUMAN," set two years later, finds Belo operating independently after the trio separates. He actively investigates Doracho Chemicals from the city's shadows, initially working apart from human ally Sonia Summers. Though still reluctant to aid humans directly, his pursuit demonstrates a commitment to exposing corruption. He eventually reunites with Bem and Bela for the final battle, signaling a shift from his earlier isolation.

His core abilities remain consistent: pyrokinesis, superhuman agility, teleportation, illusion creation, heightened senses, and monsterification—transforming from a human guise featuring white hair and fangs into a distinctly non-human monstrous form.
