Manas is a major antagonist within the Oración Seis, an elite cadre of Farmagia generals governing Felicidad under Magus Diluculum. He rules the continent of Perfectus, initially projecting an image of composed wisdom as a mentor figure. His appearance features short silvery-white hair styled in a neat bowl cut, cool blue eyes, and regal attire: a white jacket with black accents, light beige pants adorned with flame-like patterns, and a deep purple cape lined in black with ornate lavender designs.

Beneath this calm facade, Manas is an obsessive and immoral researcher consumed by scientific ambition. He conducts unethical experiments on his citizens, forcibly converting them into Reapers by compelling them to devour each other’s souls to augment their power. This process inevitably drives victims to madness, transforming them into mindless demi-beasts. Among his test subjects are Gâteau and Zucchero, individuals regarded as friends by Emero. Manas views Emero solely as a research specimen, training him to evaluate his potential to become the legendary Farmagia Hyperion—the ultimate life form.

Created by Diluculum as an Advanced Replicant with innate abilities surpassing ordinary denizens, Manas was recruited into the Oración Seis to oversee Perfectus. His experiments intensify during Felicidad’s conflict, prompting Emero’s defection upon uncovering the truth. In their final confrontation, Manas voices bitter regret over their failure to achieve the Hyperion transformation together before his demise. His creation of demi-beasts significantly fuels the broader conflict orchestrated by Diluculum.
