In a distant world, Saitama felt an odd sensation, a strange tingling in his hand. Genos noticed it too, his sensors buzzing as they picked up Kei's message. Realizing it was a call for help, Saitama looked toward the sky, a determined glint in his eyes.

"Looks like we've got another adventure," he said to Genos, who nodded eagerly.

As they prepared to respond to the call, Saitama couldn't shake the feeling that this mission would be different—that the fate of an entire world might rest on his shoulders.
