Talk about getting illogical: they summoned Yuuya to DEFEAT the evil god, but because he was only HUMAN, defeat was impossible. All he could do was seal him away for a few hundred years. Now that he's a god, he's finally strong enough, but he's not allowed to interfere with the world because of his godhood. Next, introducing Cain... another human. Following the same logic, as a human he'd ofc be too weak to kill the evil god! So, how's he supposed to defeat a god when it clearly shows us that it's impossible😅?! Author didn't think this through at all, did they? If he defeats the evil god as a human, it makes the backstory a plothole. If he defeats him after he obtains his own godhood, it again makes the backstory a plothole🫤!
