Toji, as always, has fallen into Kensuke's trap. He knows that Kensuke's words are just a means to an end, but if that's what he wants to do, Toji figures he'll be a good sport and try to go along with it.
Toji:“You sure are upfront about what you want, ain't you?”
Reichu: Toji's basically remarking that Kensuke is overly obedient to his desires. Like Toji's one to talk, right? ("Sorry, transferee, but I've gotta beat you up! I won't feel right until I've smacked you.") It's always easier to criticize others than be a paragon of virtue yourself.
