My God Group System in the Holy Grail War

Waking up in Fuyuki City with a blood-red Command Seal, Roland quickly realizes he's trapped in the deadly Fifth Holy Grail War. A powerless civilian with zero magical knowledge, his only thought is to survive the imminent conflict against powerful mages and legendary heroes. Running is his only option. But fate has other plans. Desperate, he stumbles upon the betrayed Caster, Medea, forming an unconventional contract. This unlikely alliance triggers an awakening: Roland discovers he possesses an unimaginable talent – 1200 Magic Circuits and an elusive Imaginary Attribute. Just as he grapples with this, a mysterious 'God Group System' activates, granting him immortality and the legendary Six Eyes, allowing him to perceive and instantly master any magic. Survival is no longer enough. With Medea by his side and a nascent pantheon to build, the Holy Grail War transforms from a death game into a grand recruitment drive. Can a mere transmigrator rewrite the legends of Fuyuki City and ascend to divinity, or will his newfound power be his ultimate undoing?
