However, would Aiko agree to it? After all, the last attack was aimed at Aiko. That was the reason why she felt strongly responsible. Aiko always thought of her students first. Shimizu died because she involved him. In effect, wasn't it her fault Shimizu was dead?, she might think in such a way. Thus he thought, can Aiko's mind endure it?; Hajime felt a slight fear.
Even Aiko should feel unease and fear as human who was summoned to a different world. Although she didn't lament as she cowered and trembled in fear, the reason she could work so hard was because she had her pride as a "teacher." In addition, there were "students" who occupied Aiko's mind as a "teacher."
And a student had died because of her. The impact was greater than when she had heard Hajime had died, or the time when Hajime said the cause was the backstabbing of a classmate. It would be a much stronger blade to damage Aiko's heart. It might even break her.
Hajime calculations would be affected if Aiko was broken, but he was definitely worried about her. Hajime had felt that Aiko's words were an impossible ideal, because they gave birth to a lot of contradictions.
Even so, the words said by Aiko made him think it was definitely be necessary for Yue and Shia's future happiness. That's why even if the world had changed, and even if Hajime had changed, the "preaching" of Hajime's "teacher" made him feel indebted to her.
Therefore Hajime killed Shimizu even though he would die soon enough even if he was left alone. Making a strong impression, emphasizing that Shimizu was an "enemy". This was followed by making an impression of Hajime being the one who killed Shimizu. Aiko's heart shouldn't break down. He thought it was his duty so his "teacher" wouldn't change.
"So that's what happened... Fufu, what a tsundere Hajime-san is."
"So that's what happened..."
"Indeed~, Master is unexpectedly cute."
Yue finished her explanation to the other members, and their eyes carried warmth as they looked at Hajime, but Hajime kept looking the other way.
"... But, I think Aiko noticed it."
"..."
Hajime silently turned his gaze to Yue. Yue returned Hajime's glance with gentle eyes.
"... Aiko is Hajime's teacher. A person whose words remained in Hajime's heart. That's why there's no way she didn't notice..."
"... Yue."
"... It's okay, Aiko is strong. The situation will definitely end how Hajime desired it."
"..."
Apparently Yue trusted Aiko because Aiko could at least have Hajime focus on himself. Something she couldn't do. Towards Yue who watched him with an upward gaze, Hajime responded by gently narrowing his eyes. Because of Yue's words, his worries about Aiko and future developments which clouded his mind cleared.
"Haa~, to create the world where only the two of you existed... no matter how much time passes, I will also create such atmosphere..."
"Th-This, what can I say... I somehow feel something sweet in my mouth..."
"Muu~ this one wants thee to abuse this one, but... even this kind of situation isn't bad..."
Will and the others felt uncomfortable because of Hajime and Yue's sweet atmosphere. Shia in particular was puffing her cheeks and pouting in distaste.
Yue noticed Shia and shifted her gaze towards her, and once again matched Hajime's gaze to silently appeal to him. The content was none other than "Shia's reward." Without Shia's peculiar magic; "Foresight" and her desperate action, Aiko would have become someone who couldn't return because of a hole in her head. Shia had saved Hajime's teacher.
