Zenkichi coughed into his fist, looking away when she keeps pushing and using his own words against him like that!!

"Well excuse me if your selfless heroics does spark an obvious level of concern in me. I am not apathetic," he closed his eyes and shook his head. "I was just letting you know that I will come to clean up the mess which is my job. I swear, being around you kids already makes me age faster than I did back when the actual apocalypse was happening."

He gestures behind at the buffet and the food trucks- "I suppose I owe you because of the sushi platter anyway. And keeping Akane company," he adds just to let her know how being a decent human being makes him a softie. He doesn't notice a bespectacled man in a green yukata, one of the two infamous pscientis walking around in the distance, trying to find a certain someone.
