The Heroine is My Stepsister, and I'm her Final Boss - Chapter 19: Humanity.

A young middle school student faces a life-altering choice. Destined for mediocrity and without a War Spiritual Bloodline, he dreams of transcending his ordinary existence and becoming a high-status War Spiritualist. His world is transformed when he becomes bound to the “”Godly Pet Evolution System,”” enabling him to activate his War Spiritual Bloodline and cultivate divine pets, even from the most unlikely sources.Armed with this system, he defies expectations by nurturing underdog spirits into formidable allies. The seemingly weak flower spirit evolves under his care, as does his Lord White Dragon, challenging the mightiest thunder-attribute battle spirits. Even when presented with a Diamond Demonic Spirit Card, he counters with three Epic-Demon Spirit Cards of his own.His journey takes an unexpected turn as powerful entities, including the Six-Tailed Demon Fox, the Phoenix Holy Maiden, and the Queen of the Seas, vie to become his second battle spirit. Faced with a wealth of choices, he refuses to settle for just one and ambitiously aims to harness them all.

A massive underground labyrinth awaits in an alternate world of swords and magic. With a game-like system much more familiar than spells and magic circles, Beatrice has managed her magic and risen to the position of “strongest”, but she still has her worries.

“Bghohhh!! Bshrrrr…mumble mumble…”

“B-Boo Boo! Stop! Stooooooop!! I’ll…I’ll be crushed!? I-is my, ah, love being tested!?”

Who is the legendary man named Boo Boo who, just by taking a nap, can overpower the Level Cap Holy Swordswoman? A thousand meter dragons and a proud elf girl will also show up, so what exactly is going to happen with these residents of another world!?

That feeling of ripping through your enemies and the feel of their hot blood washing over your body.

What better way to relax the body after a glorious victory than indulging in the carnal pleasure from conquered women.

All Evary Seth desires is supreme power, carnal pleasure, to screw his wife whenever he can and of course, to conquer his ridiculously powerful mother-in-law.

Seth wants to be the strongest, but who is stronger? A primordial fiend? Or its creator, a God?

What do Gods do when their biggest attack dog turns on them.

Amid the silence of the aftermath, a sealed envelope was found resting beside the fallen Infinity Blade. Its edges were worn, as though it had been carried for many years, yet the seal remained intact. Gok, known for his stoicism and strength, had written it long before the final battle, anticipating that one day his journey would reach its end.
