A member of the group Oriens within the VTuber agency NIJISANJI. He works as both a gym trainer and a hero. He is an energetic young man who is quite loud, whether in voice or text. During his debut stream, his audio was clipping the entire time; he describes himself as having a "relatively loud voice." His visual design has a lightning attribute. Lightning bolt motifs are found everywhere on his person, including his watch, tights, the soles of his shoes, earrings, and hairpins. His hair is orange with mint-colored tips at the back. The creature around his neck is his partner "Kirin-chan," whom he has been with since they met; touching this partner allows him to transform into his hero form. He is 23 years old, though he jokingly says, "Did I reveal my age? I'm a lady, so I might hide it," while claiming his mental age is permanently 23. He is 181cm tall and his birthday is August 17th. His favorite foods include tenmusu (shrimp tempura rice balls), spicy cod roe, udon, and curry rice. He also likes chocolate mint, claiming toothpaste tastes good. His favorite drink is black coffee. He dislikes cilantro and celery. He dislikes alcohol and physically cannot drink it; he turns bright red like a Darmanitan and has an alcohol allergy. His usual outfit is techwear-inspired, featuring a white, shoulder-baring futuristic jacket over a black high-neck inner layer, with an orange cloth hanging from his waist, baggy pants, and platform sneakers. When transformed, his orange hair turns a pale yellow closer to white, and he wears a black face mask. The design features turquoise blue and orange geometric patterns with lightning motifs, a single horn on his forehead, and black fingerless gloves with orange accents. His usual expression features almond-shaped, slightly drooping eyes with long lashes, giving him a gentle gaze. He often has a soft smile, giving an overall impression of being relaxed and composed. He has a slender nose and a clean, androgynous facial structure. His personality is bright, social, and friendly. He is truly kind and possesses high communication skills. However, he isn't just nice; he will get angry or step in for someone's sake. He has a laugh that sounds like a chicken. Because he shares his kindness equally with everyone, he is called a "big, kind giant." He is also a rational thinker, using his kindness and logic to help others understand things.
