The summit of these shitty cliché story where the MC is betrayed by his teammates...
With the famous unknown skills he didn't understand (it's not like you can guess the effect with the title and what's different with you...) activate just after he got kicked out and making him overpowered...
And seriously, wtf is wrong with these authors in using the Hero party to be scumbag, it's the HERO!! A strong Warrior chosen by the king or something else, OK, but not the Hero recognized by this world's system, that's not a Hero!!
If he's like that, the "God" of this world must be retarded... And since the author is kind of the God of this world, he's the retarded one...
We got the Loli because pedophilia is great, now it will be the MC living a happy and easy life because he's overpowered and the only problems will come from the stupid choices of the MC because he's just a nice and stupid pushover Japanese MC...
And I'm pretty sure the Hero party will come back and try to mess up with him instead of living their own life because they're the Hero party... And the Hero is the bad guy...
