• A professional engineer by day, but his true face is the leader of a street racing team.

• The team name is "Revenger." Revenger consists of two members, including Koji.

• His car is an old-model FR with a 5-speed manual. He pushes the chassis to its absolute limits, driving in a way that makes engineers cry (himself included).

• He is usually mild-mannered, but has a mysterious side where you can't tell what he's thinking.

• He steps up when it counts, but generally speaking, his driving isn't actually that good.

• A university student with incredible reflexes and adult charm. A car enthusiast who spends all her part-time job earnings and race winnings on her car.

• Her ride is a new-model open-top FR with a 6-speed manual.

• She claims to be a "safe driver," but she's constantly blowing past the speed limit... However, she's lucky enough to have maintained a clean driving record.

• She attends school normally with Mina.

• A simple and straightforward university student who speaks her mind immediately.

• She isn't particularly interested in cars themselves, but loves using spray cans to paint illustrations on the bodywork.

• She wears revealing clothes and catches a cold every single time. A bit of a show-off, she'll accept any challenge if provoked.

• Her car is a 5-speed FF "wild horse" left to her by her father. It has a purple lightning bolt painted on the side.

• Rumor has it her parent was a legendary street racer...?

• She is best friends with Rena.

• A street racer belonging to Revenger. She drives an FF kei car modified with a nasty-sounding aftermarket muffler to scout out rival teams in other prefectures.

• Rumor has it that no one can beat her when it comes to S-curves.

• She is usually friendly and sociable, but once she grips the steering wheel, she goes silent and expressionless.

• The owner of a bar, but his true face is a man of power who rules over numerous regions—a man who can summon multiple bodyguards with a snap of his fingers.
• Currently, he has his eye on Revenger to nip the young talent in the bud, despite their small scale.
• His car is an old-model kei car. He drives far beyond the vehicle's limits, using every trick in the book to ensure victory.
• A silent old man who always has a cigarette in his mouth.

Apparently, he bears a resemblance to a certain someone...

Also known as "Purple Eclipse"

• If a light blue sports car with a black roof and black carbon hood approaches you, you might as well give up.
