Saigu will soon find out that she accepted a pupil who cares nothing for studying, in fact one who doesn't even understand what studying is for in the first place (remember, he didn't understand he needs to study to prevent his school grades from falling). Resolve? Give me a fucking break. Was the dude full of resolve in front of them a while ago indoors? He could barely speak a word and Chikage had to take over to explain anything to the others. Unless Saigu arranges a real boot camp for the worthless boy, with the ruthlessness of a drill sergeant from the 1930's, nothing will change.
