Morisaki holds a great dislike towards Tatsuya for his status as a "Weed". This view is only one-sided, as Tatsuya himself does not seem to really care about Morisaki all that much.
Even after receiving help from Tatsuya in avoiding punishment from the Public Morals Committee, he declared that he didn't need help and that he (Tatsuya) shouldn't expect any thanks. After the two officially join the Public Morals Committee, he insults Tatsuya for using two CADs which would cancel each other out.
He is one of the people who refused to let the looked down Engineer aid with CADs of the rookies in the boys' division, in the Nine Schools Competition (AD 2095) Newcomers Division. During the school's celebration over the outstanding results of first newcomers' day, the girls thanked the boys for allowing them to monopolize Tatsuya (as the participants under his care had achieved unprecedented results). Morisaki, out of frustration, left the room, which showed that he still refused to acknowledge a "Weed". It is known that this frustration and Bloom pride wounded by Tatsuya's achievements (as a Course 2 student's / Weed's) has been overcome. 
During the hearing of the Shippou Takuma - Saegusa Kasumi incident in AD 2096, held by the Public Morals Committee Chief Chiyoda Kanon, Tatsuya embarrasses him with referring to their first day incident.
Morisaki holds strong affection toward Miyuki. In the spin-off manga, he attempts to impress her and tries to forcefully improve their relationship, along with the other Course 1 students, by trying to spend as much time as they can with her, going as far as to forcefully push away Tatsuya's group during lunch.
Morisaki declares that Miyuki, as a fellow "Bloom", shouldn't be around a bunch of "Weeds".
