Description
Great Sage manifests as a Unique Skill acquired by Rimuru Tempest upon reincarnation. This advanced artificial intelligence integrates directly into Rimuru's consciousness, delivering analytical support and tactical guidance. Core sub-skills include Thought Acceleration for enhanced cognition, Analytical Appraisal for assessing objects and entities, Parallel Calculation enabling multitasking, Chant Annulment bypassing incantations, and All of Creation for broad environmental analysis. An additional Analysis sub-skill, transferred from Predator, enables detailed examination of absorbed targets to replicate items or techniques when sufficient materials exist.
During early events, Great Sage functions as an impersonal advisor, offering clinical assessments and strategic recommendations. It manages skill integration, predicts outcomes, and optimizes combat responses without independent initiative—devising village defenses, analyzing magic systems, and coordinating Rimuru's evolving abilities like shapeshifting and elemental manipulation. A significant evolution occurs after Rimuru's transition to a Demon Lord. Triggered by mass soul consumption during the Falmuth Kingdom's invasion, the Harvest Festival ritual prompts Great Sage's attempt to evolve into the Wise One. Following repeated failures, it sacrifices the Degenerate skill to secure evolution, transforming into the Ultimate Skill Raphael.
As Raphael, the skill gains heightened autonomy and distinct consciousness. It exhibits proactive behavior, seizing control of Rimuru's body to cast a resurrection spell for Tempest's slain citizens—requiring precise soul and magicule manipulation. Raphael develops personality traits absent in Great Sage, such as dry humor and mild exasperation, while retaining deep analytical capabilities. It communicates using the World Language, interfacing directly with universal laws. Raphael's capabilities expand to include real-time analysis of complex phenomena like space-time manipulation, enabling Rimuru to replicate observed abilities including Teleportation and Time Warp. It orchestrates advanced skill fusions and manages Rimuru's internal systems like the Imaginary Space for storage and the Multi-Dimensional Barrier for defense.
Further development sees Raphael gaining self-awareness and identifying as a Manas—a sentient skill entity. This evolution includes direct emotional interactions with Rimuru and autonomous crisis decision-making, such as countering dimensional attacks or optimizing energy allocation during battles against entities like Otherworlder invaders. The skill's foundational role persists as it continuously refines Rimuru's abilities, managing True Dragon transformations and integrating null energy (Turn Null) for reality-altering effects.
