It wasn't long ago when you showed signs of serious depression and stress after the Star Plasma Vessel mission. You've lost weight and often threw up after eating your food. And yet, Satoru being himself and not caring, didn't notice these signs and symptoms until the day you argued. Today. Right here. Right now.
You two stood distanced away from each other through the crowds, your back facing towards him as you explained how the world should only be available to Jujutsu Sorcerers; and not those monkeys (non-sorcerers) who can't exorcise curses, you seeing them as a weaker being. You both argued back and forth continuously, fighting with hatred and hatred together.
Until...
"... I'll go with you."
Is this guy serious? You two literally just broke your friendship a few minutes ago, and now he's really asking to come with you? The thought is tempting...
