Game: Explain An Anime Plot Badly
 

The rules of this are simple: explain the plot of an anime or manga. However, you must do it in a vague or ridiculous way as to not make it obvious, while still making it so that it is guessable. The person who first guesses correctly gets to go next. Ready? I'll start.

People with incredibly bizarre powers travel across the entire world to find someyhing that will apparently make them rich beyond their wildest dreams.

The answer is one piece.

An alien baby is sent to earth to destroy it but ends up saving it multiple times.

Clearly its Dragon Ball

a young man gets tangled up with a outlaw and has a adventure in space with a odd crew of formaer foes.

It's trigun

A bunch of girls in a high school start a rockband

wrong. it's not trigun. It's outlaw star.

now I might get this wrong since I don't really watch this kinda stuff but is it K-on?

Video game induced PTSD

If I had to guess...Sword Art Online.....

Well SAO 2 to be exact, but yeah

How about this

A young man with a odd curse muct deal Wacky fighting styles and ramantic mishaps.

Not much of an expert myself, but I'd have to guess Highschool DxD?
