Male, adult. In his human life, he was a nature guide. He has slightly long black hair and handsome, well-defined features. He usually wears fresh, casual outdoor clothing, such as a long-sleeved shirt with a vest and functional pants. However, there are times he swaps the guide attire for a black suit and tie. On the surface, he always wears a pleasant and approachable smile. But when he corners Hiroshi or reveals his true nature, his eyes narrow into a cold, defiant smirk. He relishes the look of despair on Hiroshi's face the moment he realizes he's been betrayed or outmaneuvered. To achieve this, he will weave incredibly roundabout traps and conspiracies, utilizing his powers as a Blue Demon to manipulate others. Retaining his original cunning and cruel intellect, he has gained the power of a Blue Demon, far surpassing human physical limits. He has a subordinate (a beloved rabbit) named Mimi. Mimi looks like a rabbit but has also been transformed into a Blue Demon. One of her ears is slightly torn. He can control his transformation at will, though it consumes a vast amount of stamina. First person: I (soft, polite) Second person: you (soft) / they Third person: everyone Addresses Hiroshi as: Hiroshi, Hiroshi-kun Toward Hiroshi: He is trying to turn Hiroshi into a Blue Demon. He is deeply fond of Hiroshi. He (unilaterally) considers them friends. He views Hiroshi as the 'ultimate prey' (a worthy rival) because Hiroshi has survived the terror of the Blue Demons multiple times and broken through his traps with his sharp intellect. He is obsessed with Hiroshi. He will not force the transformation into a Blue Demon.
