Yokohama's Military Police Commander Wants to Disappear

Choga Yayoi was the commander of the former military-police unit “Rose.” After returning from a mission one day, he learned that he had lost everything overnight. His teacher, companions, subordinates, even the civilian office staff on the periphery: not one member of “Rose” had survived. After witnessing this, Choga Yayoi's mental state was deeply worrying. In the midst of his grief, he found a goal for the rest of his life after speaking with his friend Dazai, who belonged to the Port Mafia. (Dazai, after running away: If only I'd known, I'd have said a few less things back then.) Just then, Choga Yayoi had abandoned his public identity when a self-proclaimed Energy Collection System latched onto him by force and demanded that he complete collection missions. The reward for completing them was the chance to make one wish come true, within the limits allowed by the world's laws. As Choga considered how to make his wish come true, he thought this was exactly what he'd needed, and the timing couldn't have been more perfect. A smile of uncertain meaning appeared on his face. “Oh?” The little support System broke into a cold sweat, unable to tell what he meant. After thinking it over, Choga smiled and readily agreed. But the next second, he was unexpectedly caught up in a mysterious Singularity and transported to an unfamiliar world with no supernatural abilities, where people used jujutsu instead. System: “...I didn't do that.” Choga Yayoi, who had suspected as much: “...” After confirming several times that the cursed energy of this world also met the System's energy requirements, Choga Yayoi quickly adapted to his new surroundings. For the sake of his wish and a return to Yokohama, he officially began his part-time job (not really) journey. Reader's Notes: 1. Jujutsu Kaisen first, then Bungo Stray Dogs. 2. Some characters will be saved from death. 3. Many personal interpretations. Theme: With your heart set on something, hard work can make it come true.
