JoJo no Kimyou na Bouken - Mugen no Ou

Bridging the turbulent gap between the events of Battle Tendency and Stardust Crusaders, this narrative unfolds across a thirteen-year span from 1973 to 1986. Acting under the direct orders of Lisa Lisa, a specialized research team affiliated with the Speedwagon Foundation is dispatched to the historic city of Antigua, Guatemala. Their primary objective is to uncover the true identity of a mysterious serial killer who has been operating in the region, leaving behind victims struck down by an entirely unknown and unidentifiable power. As the investigators delve deeper into the string of murders, their pursuit leads them far beyond a simple case of criminal profiling. They ultimately uncover Fernando Alhorn, a ruthless gang leader whose ambitions extend well beyond ordinary organized crime. Alhorn has acquired the legendary Arrow, wielding its ancient properties to systematically awaken supernatural abilities within his followers. By exploiting this artifact, he is rapidly amassing a formidable private army, transforming the quiet streets of Antigua into the staging ground for a dangerous new threat that the Speedwagon Foundation must neutralize before it spirals out of control.
