DEMON CASTLE - Chapter 92

Aiden Nightshade wakes up in a dark, unfamiliar forest with no memories of who he is or how he got there. The air is thick with danger, and monstrous creatures lurk in the shadows, watching him. Before he can even move, a glowing panel appears in front of him.[Welcome to the Ultimate Bond System.]A cold, synthetic female voice echoes in his mind. It tells him to tame the beasts, bond with them, and grow stronger together. But this system isn’t normal. When Aiden forms a bond with a beast, it doesn’t just become his companion—it transforms into a powerful humanoid woman, one who still has the instincts and memories of the creature she once was. They aren’t just allies. They feel his pain, share his power, and their devotion to him is absolute.As Aiden explores this strange world, he quickly realizes something—no one else can do what he does. Other tamers can control beasts, but they can’t make them evolve like he can. They do have a system but nothing like his.With his growing army of beast-women by his side, Aiden will carve his own path, breaking the rules of this world. And when he discovers that the deepest bonds unlock unimaginable strength, he understands one thing—this isn’t just about surviving.It’s about rising above everything. It’s about domination.In a world ruled by beasts, only one man will stand at the top.

Noah Brown had a gift for fighting. Unfortunately punching things didn't pay the bills, at least until he died and an Eldritch god found his soul. The encounter led him to a new world, summoned by bloody cultists, with nothing but the shirt on his back, and a strange item in his system menu.

Perhaps he'd finally get to put his gifts to good use.

I, an ordinary high school student, Kimizuka Kimihiko, who easily gets involved in things, was appointed to take care of mysterious attache cases by mysterious men in black suits. After meeting a beautiful angel-like detective girl, named Siesta in a hijacked plane, I became her assistant.

And from there–

[You deal with the beehive, and I’ll restrain the enemy.] [Don’t make plans that make me the victim.]

We had those kinds of foolish conversations, all while being completely broke every day and fought against . Even when there were hurricanes, the weather-beaten duo sleep past it. Sometimes when we saved money at a casino, we would jump around on the beds at a resort hotel, only to be broke again the next day. We would walk through deserts, traverse through jungles, conquer mountains, cross oceans– The great detective and her assistant would go through these dazzling adventures–

Until she died.

And this story starts from 1 year after that incident.

I’m the only one who’s left, but I carry on her remained wishes.

This story is far from over..

Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.
…
It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??
