What Are The Best Fan Theories About 'Monster Integration'?

I've been obsessed with 'Monster Integration' theories, and one standout is the 'Symbiosis Evolution' theory. Fans speculate the protagonist's monster isn't just a tool but a dormant higher entity slowly rewiring his DNA. Clues? His reflexes sharpen unpredictably, and he starts craving raw meat—traits his monster species shouldn't trigger. The theory suggests the final arc will reveal a fusion beyond integration, where human and monster consciousness merge permanently. Supporters point to Chapter 47's cryptic mural showing a two-headed figure, which might foreshadow this transformation. Another cool detail is how his scars glow during battles—maybe early signs of cellular rewriting. The theory gains traction because it explains why lesser monsters instinctively flee from him despite his low rank.

The most compelling theory I've encountered revolves around the 'System Glitch' concept. It proposes the integration system isn't flawless—it's actually breaking down, and the protagonist is an unintended byproduct. Unlike others who bond with one monster, his ability to switch partners hints at system corruption. This aligns with the recurring system error messages in later volumes, which the author never fully explains.

Another layer suggests the monsters aren't just beasts but fragments of a shattered ancient intelligence. The protagonist's unique integration style allows him to reassemble these fragments unconsciously. This would explain why his combat strategies become eerily precise against opponents he's never faced—the collective monster memory guides him. The theory delves deep into lore, referencing the 'Crimson Codex' in Volume 9 that describes a 'splintered mind' waiting to be whole again.

What seals it for me is the protagonist's recurring nightmares of a labyrinth. Fans interpret this as him accessing the system's backend—a digital representation of the fractured monster consciousness. His eventual mastery over multiple integrations without backlash could mean he's repairing the system itself, setting up a finale where he becomes the new core.

One underrated gem is the 'Reverse Integration' theory. Instead of humans controlling monsters, what if the monsters are subtly influencing their hosts? The protagonist's personality shifts—increased aggression, heightened senses—mirror his monsters' traits even when they aren't active. Some fans believe this isn't just side effects but deliberate conditioning.

Key evidence includes the 'blackout periods' where he loses time during battles, later finding enemies defeated in ways his registered monsters couldn't achieve. The theory suggests a hidden hierarchy among monsters, with certain breeds using humans as vessels to escape their dimension. It recontextualizes the integration ritual scenes; those glowing runes might not be contracts but prison bars weakening.

The most chilling part? His first monster—a low-tier 'Grasper'—was supposedly random. Theorists argue it was a plant, choosing him because his genetic flexibility made him the perfect host. This would explain why higher-ranked monsters instinctively avoid conflict with him—they sense the Grasper's true nature as a vanguard for something far worse.
