After a string of isekai anime in which the MC is ridiculously, along comes a show that flips the script, and it’s pretty refreshing. When Iwatani Naofumi thrust into a different world due to a summoning on the other side, absolutely nothing goes right.
Of the four young men summoned, he’s by far the weakest, and isn’t even given a real weapon, only a shield. But he’s still optimistic he’ll be able to fight once supplied with a party of elite warriors.
…Only none of those warriors join his party. Eventually, one of them finally does, and she just happens to be the one he considers most attractive. This adventurer, Myne Suphia, seems to embody a stark reversal of fortune for Naofumi.
He’s given more cash than the others due to his smaller party, and Myne shows him a good shop to buy armor for the two of them. They fight a few low-level balloons out in the field, return to town, and make a modest profit.
It’s a confidence-building first day for Naofumi, to say the least. But that night, after refusing to drink any wine with Myne, he goes to bed and wakes up seemingly in, well, yet another world.
Not literally, mind you, but he’s been robbed of all possessions, summoned to the palace by knights, and then Myne, hiding behind one of the other summoned heroes, accuses him of attempting to rape her. When no one’s watching, she indicates screwing him over was her goal all along.
And boy, did it ever succeed: Naofumi now disgusts both his fellow heroes, the king, and everyone in the kingdom (news and rumors travel at lightning speed, despite the renaissance-esque tech-level). There’s no disputing the accusations against him, so Naofumi decides to take all the hate and loathing in stride.
If this world and its people are going to hate him despite the fact he didn’t do anything, so be it. The merchant he dealt with before seems to see the injustice in his eyes and sells him a cloak at a steep discount, which he wears when leveling up all by his lonesome…a slow and laborious process.
When some goons in the tavern mockingly offer to join his party, Naofumi won’t get fooled again; he’s been thoroughly jaded by this new world, and scares them off with some of the monsters he kept alive as a haggling tactic. A strange, squat little fellow in top hat and tails notices him and takes him to view his wares; he deals in demi-human and beastman slaves, revealing another distasteful part of this world.
Naofumi spots one sick demi-human— a girl with bear ears—and looks poised to buy her. But likely not to use as a slave, but as a companion on his quest to save a world that hates him, because no full-on humans want anything to do with him. Weak in power, scant in equipment, and victim of false intrigue and injustice…looks like we have ourselves a good old-fashioned underdog.
