The Most Bastard Hero in History

I was summoned by the brave as a bodyguard to defeat the devil with the brave. But as a hero, Eileen Till is a complete bastard. She will take the opportunity to extort 1 million gold when running errands for others, and she is also the weakest hero in history with a negative level of 100. Not only did she make us a laughing stock, she also made our trip more difficult. In addition to her, there is also an idiot magician who can change from male to female; and a female elf archer who always likes to fight in melee. And I am the only normal person in the team So I went on a ridiculous trip with this group of problem children while searching for information about the Demon King!
