Shimizu who had finished the experiments in the Imperial Capital's outskirts thought it'd be good if he could control strong demonic beasts. However, he felt intimidated to go towards the dungeon frontline just like Kouki's party. Then at the time he was at lost of what to do, he heard the talk about Aiko's bodyguards. If he joined them, he'd be able to encountered a good demonic beast or so he thought.
In the end, Aiko's party came to Ul town, then he heard about the demonic beasts in the mountain ranges area in the north and he was lost in greed when he thought to make them his subordinates. In their next meeting, everyone would be in awe and respect towards his great achievement, and he'd be treated as special or so his delusion went.
Normally, for the short amount of time of around two weeks, no matter if Shimizu was a genius in dark magic, and he used the efficient method by only brainwashing the leader of the groups, 1,000 was the limit. Moreover, it would only be those in Brutal's level in the second mountain range.
However, he was helped by a certain existence, and he was able to control Tio, who gave her power to Shimizu to efficiently brainwash even the demonic beasts in the fourth mountain range by chance. And at the same time, that certain existence promised him to reinforce him with troops of demonic beasts every day, and Shimizu's bound of reasoning completely came off. Finally, as he was soaked in joy that he was indeed special, the large crowd in his full control was turned towards the town.
Thus as the result...
He was turned into such misery for those who saw him, and he was made to kneel in front of Aiko and the others. By the way, the reason why he looked like a defeated soldier was because Hajime dragged him using magic-driven two-wheeler on the ground which covered with demonic beasts' flesh and blood coupled with the fluttering cloud of dust. Shimizu was unconscious with the white of his eyes displayed, and when they saw he was brought to the town with his head repeatedly hitting the ground, Aiko and the others' expressions were cramped.
By the way, their current location was in the outskirts and in this location were only Aiko, the students, several people from the bodyguard Knights and town leaders, Will, and Hajime's party. As expected, if the mastermind behind the attack was brought to the town, the commotions would become bigger and it'd be difficult to hold a conversation or so their reason. The town leaders which remained inside the town were currently busy with post treatment.
Aiko had stepped up towards Shimizu who was collapsed with the white of his eyes shown. His appearance which wearing a black robe, following by the fact he was dragged back directly from the battlefield became unassailable proofs that he was the culprit behind the attack. It was a fact she didn't want to believe as Aiko's expression warped in sadness, and she shook Shimizu to woke him up.
David and the others told her to stop it because it was dangerous, but she shook her head to refuse them. The same thing happened with the restraint. It was released because she wouldn't be able to hold a good talk with Shimizu with that on. In the end, Aiko was only wanted to talk as a teacher and a student.
Before long, Shimizu's consciousness begin to return from Aiko's call. He looked at the surrounding with a blank look, and maybe because he understood his situation, Hah, he raised his upper body. He immediately tried to distance himself, but maybe because the damage on the back of his head, he staggered and fell on his butt, then backed away as is. With caution and abjection, he had a mixed expression with irritation excluded, and he looked around.
