I made it 90 pages before I just couldn't take how immature the MC is, and how childish the antics were.
The MC is a young guy going to college and living in an apartment with two other guys when the world ends. The MC's one roommate ends up in new world ,and the roommate is now a 2' tall piglet that unfortunately can talk. Both the MC and the piglet have the maturity level of a 6th grader or a moronic frat boy. The MC picks a fighter class, while the piglet is a NPC. At one point, the MC uses a lighter to allow the piglet to use a fart as a flamethrower. I kid you not. And, the piglet gets a skill "Farts of Destruction" for it. 6th grade humor.
Then they get to the arena, he gets selected last by a trainer, and has to fight a tough creature. His weapon is knocked out of the arena, so he steals the weapon of a nice young woman who was friendly to him so he can continue the fight, and said new weapon gets broken. The friendly woman now has to fight her life or death fight with a subpar weapon she's never used before. And when she gives the MC grief and a cold shoulder because of these events, the MC feels she's being immature and a brat.
If you posted the MC's behavior to the subreddit (paraphrasing the title to avoid profanity) "Am I the jerk", the overwhelming response would be YES.
Between how much of a whiny jerk the MC is, and the potty humor, it was an easy choice to bail on this book. It only gets more than 1 star for the cover art.
