In the real world, an ordinary Japanese high school student is on his way to a Dragon Ball event and makes a detour to hit on a cute girl. Unfortunately, he meets with an unfortunate and fatal accident before he reaches her and, to his great surprise, wakes up in the Dragon Ball universe as Yamcha! Being a Dragon Ball fan, he knows exactly what misery awaits him as Yamcha, so he takes matters into his own hands and vows to make Yamcha the strongest Dragon Ball character ever!
The work contains examples of:
- Adaptational Badass: This trope is invoked for Yamcha. As the title suggests, the main character is an ordinary teenager who dies and gets reincarnated as Yamcha. Being well aware of what happens to Yamcha, he decides to train hard and change that. And he succeeds. By the time the Saiyans arrive, his power level is over 10,000, letting him easily wipe out all the Saibamen singlehanded and defeat Nappa on his own. Even though he's not quite as strong as Vegeta, he's still powerful enough to team up with Goku to defeat him.
- Can't Catch Up: Played with. He keeps up with Goku throught the Saiyan Saga but by the time Cell appears, Yamcha realizes he won't get much stronger and decides to focus on enjoying his life and wooing Bulma.
- Cosmic Chess Game: The ending reveals the entire thing was a board game between Gods of Destruction Beerus and Champa.
- Look Behind You: Yamcha pulls this on Vegeta during the Saiyan Saga, shouting "Look, it's the God of Destruction, Beerus!" Again, it works.
- Reincarnate In Another World: The main character dies in the real world and gets reincarnated as a character from the Dragon Ball universe.
