A 20-year-old shut-in is suddenly transported from his apartment, only to appear in front of a goddess who offers him a second chance at life. Although she grants him overpowered magical abilities in this new world, when he awakes as the newborn Prince Reinhardt, his talents are only measured at Level 2. Thinking their child to be an abysmal failure, his royal parents abandon him in the woods. There, the prince, who names himself Haruto, encounters Flay, a Flame Fenrir who decides to devote her life in service to him. Haruto's relative, Gold Zenfis, meets them both in the woods and decides to adopt the child as his own. Nine years pass with Haruto under the care of the Zenfis family. His mastery over his overpowered barrier magic increases by the day, though Haruto would rather not use it to help others. He practices his magic in secret, preferring to have his family believe that he is weak. However, his younger sister, Charlotte, discovers his strength, and with the assistance of Flay, Haruto protects her and the rest of the Zenfis family from harm. With a shifty plot stirring in the kingdom, Haruto only wishes to stay inside and watch anime, but it seems he will have to use his magic to keep the family that took him in safe.

However, a racing circuit known as MFG, which employs traditional internal combustion cars, is garnering popularity worldwide. Kanata Livington, a 19-year-old Japanese-British racer, comes to Japan after graduating from a top racing school in the United Kingdom to take part in MFG and find his missing father, Ken Katagiri. Kanata moves to the home of his late mother's friends—Mr. and Mrs. Saionji—and enters the race under his father's surname, borrowing a Toyota 86 from Ogata, the couple's family friend. Despite the overwhelming disadvantages in specs, Kanata makes it to the top 15 while racing top-tier supercars, demonstrating his phenomenal skills.
