Dachou Juujin no Hachamecha Musou - Aho Kawaii Saikyou Shuzoku no Leader ni Narimashita

Cute but dumb as hell... and somehow still the strongest! ...Reincarnated as an ostrich beastkin with innate physical ability!? With intelligence from my previous life, I lead a flock through a monster-filled hellscape just to stay alive... One day, after saving a party of human adventurers from certain doom, I finally made contact with the civilized world I had dreamed of!!! Unlike the uncommunicative ostrich-kin I'm used to, I'm overjoyed to meet people I can actually talk to... However...!
