Oh good, another villain too maniacal to realize their shit plan is, in fact, shit.
One of two things will probably happen next chapter. Either the MC party will slightly struggle, as they came across an unfamiliar enemy. The other team will join them and something about the male MC having "muscle". Or, the MC party will slightly struggle, the elf or female MC will get hurt, and male MC will activate Saitama, blowing the beast away. Causing the villain to have a, "how could this happen?" moment, will return to her 'master' to report that male MC is too stronk and likely be punished by said master for failing them. Or, bonus round, both happens.
The tropes are real, people.
Plus: I didn't see a harem tag. I'm getting harem vibes from elf. Anyone else feel it? I've read enough Isekai to know where this is going.
