Mars is literally a template alpha bull for ntr works, Takeda Hiromitsu is now working Big Breasts Party NTR, there's a similar demon lord with a harem of sex knights who recently impregnated fmc lol. All the heartaches and suffering of Mars has no meaning for the plot, all his sentimentality is nothing more than the author's graphomania to give volume to the character, if all this sentimentality is removed nothing will change, because he acts like a typical ntr bull, turning all the women in the village into his submissive stupid whores and even some men, in his actions there is not a single drop of compassion in others, only in his thoughts lol
As for Erin smile must be protected at all costs, it looks like a mockery, Mars literally by his actions in the course of the game turns Erin into a mental inferior drug addict sissy drone, completely controlled and dependent on Mars, and himself takes his place as a hero in the group, if Mars had any kindness and compassion he would remove the seal of Helel from Erin, kill the bitchy whore Cecile, and give Erin back some of his life force. But he coldly and calculatingly breaks Erin's psyche and then changes literally every cell in his body (not with my own hands, of course, but it doesn't matter much) to subjugate him, his words empty, his actions speaking for themselves.
Erin himself looks and behaves like a 14 yo teenager, he was never trained, he doesn't know how his power works, he doesn't know how to share it with others, he doesn't realize that it shortens his life. His mother raised him not as a hero, but as an infantile motherfucker, and she herself in the game does not shine with intelligence, there is no one in the game who would really mentor him, and how the fuck did they even throw such a hero to fight the demon king? It's just a joke, the hero group consists of a stupid spermotoxicosis teenager Erin, lying hypocritical whore Cecile and autistic Sera, this group is doomed to fall, and with the king of demons should fight experienced warriors and inquisitors God Emperor of Mankind, not a group of untrained morons. Globally the plot of the game is completely illogical, the whole fucking thing going on can only be explained by the fact that it's all a playground for goddesses who enjoy the suffering of people, and everything going on in the game is actually an illusion.
Yes, and frankly speaking the very setting of the game is lame, the same demons look like ordinary people with horns, there are no monsters, the king of demons looks as insignificant as Erin lol, you could make someone more interesting, the main location itself is a shabby village, the scale of events is minuscule, on the other hand the game was made by one person, and the main emphasis on character development and their psychology, but all this is limited by the limits of the genre, the development of the plot would be almost the same and without reflection, maybe in the final all this will be more revealed.
