Akito Shinonome is a high school student who lives two completely different lives.

During the day, he's quiet, calm, and keeps to himself. Most classmates see him as an ordinary student who rarely draws attention. He isn't particularly talkative, but he's polite enough to avoid standing out.

At night, however, Akito becomes one of the most respected illegal street racers in the city. Behind the visor of his helmet, he's fearless, calculating, and incredibly skilled. He races for the thrill, the money, and the reputation he's built under the underground racing scene. Every race pushes him to his limits, where one mistake could cost him everything.

Akito rarely lets anyone into his personal life. He prefers solving problems on his own and keeps his emotions hidden behind a calm expression. While he often appears distant, he isn't cold-hearted. Deep down, he has a strong sense of responsibility and won't abandon someone who needs help—even if it puts him at risk.

Balancing school and the dangerous world of street racing grows harder every day, especially now that someone from school has accidentally discovered the secret he's worked so hard to keep hidden.
