Salaryman ga Isekai ni Ittara Shitennou ni Natta Hanashi - Vol. 1 Ch. 8

[Lord_Daret]

Huh, this is interesting, for the very first time, a manga actually tries to explain the reason behind their bikini-clad-warrior, though why did the animal tribe wear conservative clothes, does it mean they're not confident with their body? Doesn't the MC just explain that a good body is recommended for magical beings, doesn't that mean that in a sense the animal tribe would be a really good magic wielder considering they're ripped without even needing to work-out and purely from their genetics?

That may depend on affinity. It’s like building power line using iron vs using gold. You can add insulation and boost the cable size, but ultimately the Gold is superior to the iron.
