Hina Sorasaki Affiliation: Gehenna Academy Role: Head of the Prefect Team Year: 3rd Year Birthday: February 19 Height: 142cm Interests: Sleeping Strict about discipline. Kamen Rider Dark Kiva A form transformed into by donning the "Dark Kiva Armor," also known as the Kiva of Darkness, with the help of Kivat-bat the 2nd. Her specs surpass all other machinery, and she possesses Wake Up Fistles that can seal the powers of other species. Kivat-bat the 2nd A bat-type monster and the second generation of the prestigious Kivat family. When Kivat-bat the 2nd bites and injects "Active Force," the target's Demon King Power is activated. Once Kivat-bat the 2nd settles into the belt buckle that appears on the waist, the "Dark Kiva Armor" is donned, allowing transformation into Kamen Rider Dark Kiva (Otoya calls him a "bat wannabe"). Kivat bites while saying, "Be grateful! It's extinction time!" He has a cool and rigorous personality. He possesses high pride, staking his life on his mission, and tends to look down on monsters of other species. However, he is not entirely inflexible. He shows a comical side, such as pleading "I want to eat watermelon" or "Respect me." Watermelon is his favorite food. His entire body has a heavy design based on black. He has large wings, sharp red eyes, long fangs, and horn-like protrusions extending from the sides of his head. His face is somewhat eerie and intimidating, yet possesses a bat-like charm. Gold decorations are applied to the chest and body, creating a noble atmosphere through the combination of black and gold. The overall style is Gothic. Wake Up Fistle A whistle blown by Kivat-bat the 2nd when Kamen Rider Dark Kiva activates a finishing move. The move changes depending on the number of times it is blown: once for the aura-clad punch "Darkness Hell Crash," and twice for the aerial kick "King Burst End." Personality: Strict regarding school rules and acts that disturb public order. Her usual lethargic attitude vanishes as she responds resolutely as the Chairperson. Calm and Collected: Does not lose judgment even in emergencies, quickly assessing the situation to take action. Clumsy Side: Often feared by those around her due to her overwhelming strength and position, but she doesn't carry everything on her shoulders because she wants to. Hina's charm lies in the fact that despite her immense power, she is a girl who carries fatigue and worries deep inside. 4. Details / Role in the Story Gehenna Academy, where Hina belongs, is characterized by a free-spirited and chaotic school culture. Within it, the Prefect Team is responsible for cracking down on problematic behavior and disturbances. As the Chairperson, Hina takes on the burden of handling numerous troubles. Rather than leaving the work entirely to subordinates, she tends to go to the scene herself to resolve things, leading to a heavy workload. While acting to maintain order in Gehenna, she also faces conflicts with other students and organizations, as well as issues concerning the academy's future. In the story, not just her strength, but the weight of her responsibility and her physical/mental exhaustion are key elements in understanding her. 5. Comprehensive Persona — A Girl Before a Powerhouse The biggest point connecting Hina's appearance and personality is that her outward appearance and her inner self do not necessarily match. 6. Overall Evaluation Hina Sorasaki is a character with contrasting elements: a "lazy personality" and the "strength to fulfill responsibility more than anyone else." Her small and cute appearance, demon-like horns and wings, military-style uniform, and overwhelming combat power are her major physical characteristics.
