After a brief thought, Watanabe Gengo brought up the question that could change the tide.

"So, you guys came here because you knew I was working here, is that why you came?" Watanabe Gengo played with his walking cane, lowered his head, and asked without looking directly at the two children's faces.

"Yes, we are investigating the truth behind the abduction incident last time." Uesugi Yuki immediately picked up the topic. She had been struggling for a while to steer the conversation, but now that Watanabe Gengo brought it up, she pounced on it like a cat seeing catnip.

"The truth?" Watanabe Gengo caught the key point in the statement and repeated the word with confusion.

"Wasn't that incident resolved and the culprit caught?" Watanabe Gengo didn't underestimate these two children because of their age. Instead, he asked the question seriously and adjusted his standing posture to a more comfortable position, preparing for a potentially long conversation.

"No, Akao is not the mastermind." Mizuo also gradually got into the conversation and redirected his attention from curiosity.

"Akao?" Watanabe Gengo pondered on this name for a while before recalling that the person in charge seemed to be called that.

"Ah, that useless guy who talks a lot." Watanabe Gengo scratched his head and finally matched the name "Akao" with the corresponding person.

"Now that you mention it, he doesn't seem to have the leadership and strategy skills." After recalling Akao, Watanabe Gengo didn't hide his disdain. This disdain, combined with his inherently mocking appearance and tone, became even more scornful.

"But how did you know that someone is behind him? Is there any evidence?" "Um... actually, in the photos I took last time, there is one..." Mizuo spoke while opening his small backpack and took out a photo, handing it to Watanabe Gengo.

In this photo, two men were captured. One was Akao, and the other man's back was visible. The usually arrogant Akao appeared humble and respectful in the photo, while the unknown man was about to get into a car, facing away from the camera, and the location was the underground garage of the building used by the criminal organization at the time.

"So, you suspect that this man is the mastermind behind the last incident?" After looking at the photo, Watanabe Gengo returned it to Mizuo and asked.

"Yes, we think Akao is just a pawn, a scapegoat." Yuki and Mizuo answered in unison.

"As evidence, this photo alone does not explain so many questions..." Watanabe Gengo frowned and said.

"This man may be an unrelated important figure, or... suppose there really is a mastermind, does this man in the photo have higher-level people behind him?" After careful consideration, Watanabe Gengo posed this question, leaving Yuki and Mizuo speechless, unable to respond.

They didn't think as deeply as Watanabe Gengo did, considering multiple possibilities. They believed they had grasped the entire truth just because they had caught a glimpse of it.

"So far, have you found any relevant clues about this man?... Wait, are you here today because you want to ask me for clues related to this man in the photo?" Watanabe Gengo immediately smiled bitterly as he realized the content of his own words.

"Unfortunately, I'm just a temporary worker and haven't had any contact with the man in the photo. This silhouette is also the first time I've seen it, and I don't have any impression."
