Description
Kazuki Shiranui, a third-year student at Seigetsu Academy, serves as the Student Council president. Born on April 19, he is an Aries. He stands 178 cm tall, weighs 62 kg, and possesses grey hair, green eyes, and blood type O. He typically wears his school uniform with the jacket unbuttoned and uses glasses for paperwork.

His parents died in a car accident during his childhood. Though he possesses the ability to see the future, he could not prevent their deaths, leading to deep self-blame. This guilt drove him into a rebellious phase of street fighting to suppress his emotions. After the accident, his uncle, Shoujirou Shiranui, took him in, and he later learned he has a cousin named Ai Takanashi.

In elementary school, Tsukiko Yahisa defended him from bullies, sparking a close friendship that included Kanata Nanami and Suzuya Tohzuki. They often spent time together at a Shinto shrine. Bullies later targeted Tsukiko as Kazuki's weakness, locking her in a shrine storage room. The incident traumatized her and caused temporary loss of speech. Upon finding her, Kazuki decided she should forget him to spare her further pain. Tsukiko lost all memories of him, and Kanata and Suzuya agreed to pretend he never existed.

Academically, he repeated a year after saving fellow student Shirogane Oushiro from falling out of a third-story window. Kazuki took the fall instead, resulting in a two-month hospitalization. Oushiro, consumed by guilt, intentionally repeated his own year to start fresh with him, cementing their close bond.

As Student Council president, he personally recruited Tsukiko Yahisa, Hayato Aozora, and Tsubasa Amaha during their first year, foreseeing a shared happy future. He enforces a first-name policy among members to foster bonds and designates Hayato as his successor. His leadership combines charisma with a pushy, controlling approach, extending to protecting Tsukiko through his "leader's instinct."

Driven to be the best, he often chooses difficult paths to challenge himself. He maintains a carefree, exciting demeanor but exhausts himself through his efforts. His precognitive abilities evolve over time; he learns to control them to protect loved ones, despite initially hating this power. Friendships, particularly with Homare Kanakubo and Oushirou Shirogane, help him overcome guilt and focus on the future. Tsubasa Amaha nicknames him "Nuinui."
