Kouki himself was extremely down that he was unable to do anything once again and saved twice by Hajime, the fact that Kaori left him for Hajime (Kouki recognized it within himself) was also added in, he wasn’t able to hold any good feelings for Hajime.
It was, the so-called “Jealousy”, however Kouki himself was not aware of it. It wouldn’t be easy for him to admit it even if he had noticed it. If he recognised it, whether he moves forwards or looks away out of convenience…...depends all on himself.
Both Kouki and Shizuku couldn’t be said to have been in bright states, because Ryutaro is a muscle-for-brains he’s not reliable, and all classmates were depressed in general.
At times like these, it would usually be Suzu’s time to show her abilities as a mood-maker and brighten things up but, without a question the actual person is in low tensions, the smiles that shes shown occasionally were painful. It seems to be majorly due to what Eri had said to her. It’s understandable. Throughout many years, the person who was thought to have been her best friend had only thought of her on the level of being a convenient tool.
Even still, the entire class hasn’t completely fallen, the only person moving in order to reconstruct the Kingdom single-mindedly was probably only Aiko.
Aiko was also worried about Kaori, if she could, she’d do anything but, when weighed against what Hajime and them were trying to do, with Yue and Teio there she understood that she had no turn. That’s why she couldn’t neglect the students who remained damaged on the ground and decided to stay.
Because Aiko firmly had 1 on 1 communications with her students and encourage all of her students to work to their potentials, they were able to move on now.
By the way, Aiko had obviously known what had happened to the Church, although she knows more about it than anyone else, she stubbornly sealed her lips.
That was in order to not obstruct Hajime and them, and at the same time, every time she remembers what she had done, her mouth becomes heavier. Even if it was an unexpected result, her resolution to go through with it was true. That’s why, when Hajime and them came back, she planned on telling Ririana and them the truth…...police officer, it’s me.
Although Aiko seemed to be behaving brightly, on the inside, she was trembling in fear. She herself aided Teio in the obliteration of the church, if the students had known that she was involved in the blast which killed Ishstar and them and the Knights then, what exactly would they think of her?
