They are losing to a slime... I thought these people ware supposed to be strong compared to regular humans, yet they are losing to a slime, a single slime, multiple super power users are losing to a slime, it's not even a king slime.
Also this plot is strange, translation errors? I thought they ware supposed to save someone? Is it the girl at the end that they are "saving"?

I think the thing he need a pokeball.
