Humanity is humanity. Humans have never needed to become immortals or gods to gain great power. We can move mountains and fill seas, soar through the sky and burrow through the earth, and destroy the heavens and the earth.
The immortals, gods, demons, mechanical lifeforms, and all the rest in this world are simply different races.
On this deep-blue planet, the birthplace of humanity, we once fought against the myriad races of the universe and waged war in its mysterious depths. Of course, we paid for it in blood and tears. When we were on the verge of destruction, we had no choice but to seal it away.
Now this deep-blue planet is about to be unsealed, and the humans living on it must reclaim their former glory.
From the start, all he has is a big yellow dog. Watch as this chuunibyou protagonist step by step reclaims humanity's glory and wages war among the stars.
