Have you seen no game no life?
The MC is still a human but he's just smart with no over powered characteristics and humans are the weakest race.
i've seen it , i'm talking about most of harem manga in particulary. Yeah it's rare to see a manga where humans are week.
Tensei Shitara Slime Datta Ken (slime)
Tensei Kyuuketsukisan wa Ohirune ga Shitai (vampire)
Re:Monster (goblin)
Isekai Onsen ni Tensei shita Ore no Kounou ga Tondemosugiru (hot spring)
Shirokuma Tensei (white bear)
S-Rank Monster no Behemoth Dakedo, Neko to Machigawarete Erufu Musume no Kishi (Pet) Toshite Kurashitemasu (chimera kitty)
Kumo desu ga, nani ka? (spider)
Tensei Shitara Ken Deshita (sword and cat girl)
Why is it that in manga (harem in particaliry ) the MC is always a HUMAN and that humans are always the strongest ,even though that they are obviously not.
Come on someone make a manga where the MC isn't human and that humans are not the strongest.
