Time Skipping Battle Junkies

She used to be a planet destroying saiyan who traveled around the galaxy with no one powerful enough to stand in her way. It was a simple and joyous life for Zina until she lost a duel with a purple haired saiyan and was teleported to a city outside of time itself. There she meets a group of insufferable non-saiyans who insist on following her around, and being her "pal". This nightmare only seems to get worse as she manages to lose a fight to a lowly human of all people! Not only that, but this human tricked her into becoming his student and time traveling partner. Now a normal day for Zina is being dragged across time and space with a pack of brain dead idiots fighting all sorts of powerful creatures. This new life of Zina's certainly isn't stable, but at least she can always find a good fight.
