Human Guardian Tree

A ferocious bird with a wingspan of 100 meters flew over from high altitude. The blood colored giant beasts are jumping and weaving among the tall buildings, searching for their prey. On the road below, a terrifying creature shrouded in thunder has stepped on giant craters. Helpless humans, hiding in the ruins of the city, shivering and trembling. Outside the city, a giant tree that covered the sky and sun opened its eyes. "This is the city I sheltered. Exit, the violator dies!" In an instant, all beasts surrendered. PS: Exotic Beast+Leading the Mainstream! In the early stage, the focus was on subduing mutated animals and establishing one's own power. In the middle and later stages, the protagonist can transform into a human.
