Manga by author Umezawa Haruto

From Eternal-Blue: Basically, this manga follows Hibino Hareluya as he tries to "conquer the world" by dealing with the everyday punks on the street. Always ready to fight and always winning his fights, he just finds himself in more and more trouble. Along the way he surrounds himself with friends who are all very strong in their own unique way. It's from the same mangaka of Bremen.

Reiji and Kasuga head out to Tokyo to become the "Gods of Rock," but they seem to always attract trouble. On their way, Hayama Ryo and Fujii Ran join them in their quest. Despite its rockstar type look, this manga really is about action.

The day after he finds himself dumped by his girlfriend, Sorayama Shun recieves a letter... from himself? The letter was from Shun 25 years ago for his future self. The letter reminds him of the time when he dreamed of owning a Countach and being a successful professional racer. With loads of luck and his ambition to make his childhood dream come true, he finds himself as a new owner of an LP400 Countach.
