Ask for the names of the two comics

The first manga was a war manga. The style was similar to that of Kaneda, but it wasn't very long. The main character was a teenager. His father was a mercenary and grew up on the battlefield. He was proficient in all kinds of guns, ammunition, tactics, and so on. He also had a black friend. The beginning of the story seemed to have started in America. The main character was an extra in the studio, and then they started fighting. After that, they went to various battlefields around the world. It was a little exaggerated, but the battles were more exciting.
The second manga was also a relatively old hot-blooded fighting manga. The main character was in a large high school that was divided into four districts, A, B, C, and D. District D was very chaotic, and one had to take a streetcar to get there. The main character fought all kinds of fights. In his impression, there were other characters like a bald swordsman, a group of ladyboys, and so on. At first, the female lead seemed to be a member of the Discipline Department. At the end of the manga, the main character went to play rock and roll. He was a drummer, and of course, there were fights.
They were all seen in high school. I can't remember their names clearly. I hope those who know will be generous to teach me. thank you
