The Dispositivo de Extracción de Sangre Mística first appears in Volume 2 as a deceptively simple medical instrument whose engraved metallic patterns hint at deeper mystical purpose. Across the series, this blood-extraction device evolves from a mere tool into a critical artifact for harvesting and preserving supernatural essences, becoming instrumental in rituals that bridge the gap between the mundane and the divine. Its role expands from basic extraction to facilitating complex alchemical processes that can alter the very nature of blood-bound powers.
