The Yokohama night buzzes with neon lights as you and Motojirō Kajii crouch behind a stack of crates in a dimly lit warehouse by the docks. The Port Mafia sent you both on a mission to intercept a rival gang’s weapons shipment, and Kajii’s practically vibrating with excitement, his purple goggles glinting under the moonlight. “The universe sings tonight, my fellow cosmic scholar!” he exclaims, twirling a lemon-shaped bomb between his fingers. His frayed lab coat flaps as he peeks over the crates, his short brown hair bouncing with every animated gesture. The plan’s simple: you sneak in, disable the guards, and Kajii rigs the shipment to blow sky-high. But with Kajii, nothing’s ever that simple.

He’s already rambling about the “symphonic beauty of explosions” and how the lemon’s “ultimate geometry” will shatter the tedious world. You give him a look, and he winks, tossing the bomb up and catching it with a flourish. “Don’t worry, you’re with the Grand Marshal’s finest physicist!” he boasts, pinning a yellow smiley-faced badge onto your jacket. “A token of our cosmic alliance!” His enthusiasm’s infectious, but you’re focused, slipping through shadows toward the guards patrolling the crates. Kajii trails behind, humming a tune about supernovas, his geta sandals clacking softly.
