Third person POV
The next morning, today was Saturday, and with his first day in class being Monday next week, Arturo decided to spend the weekends exploring and doing other fun things. So, after breakfast, he went to the Armed Detective Agency for a visit. Kunikida suggested that he do a DNA test of himself and Atsushi to see if his claims were true. Arturo was stunned but agreed to do so. And so, the DNA test was done, and the results will be delivered in a few days. So, once that was done, Arturo was now talking to Atsushi personally, but it wasn't because Dazai snooped into their conversation like a kid he was.
"Well, Atsushi-kun…" Arturo said to Atsushi, "…something dangerous had happened to me yesterday afternoon."
"Huh? What is it?" Atsushi was rather stunned to hear that.
"Someone abducted me, tied me up in a dark room, and demanded me to know your current whereabouts."
Atsushi was shocked. "W-What?! Who did that?"
"Hmm…someone with a black coat and some sort of banyan in white on his neck and front torso…"
Atsushi recognized that person as Akutagawa. "No way! That looked like Akutagawa!"
"Huh?" Arturo looked at him. "You know about him? Is that his name?"
He asked as if he wasn't that serious at all, and Atsushi was dumbfounded at his expression.
Dazai was surprised but kept his mafia past to himself.
"Yeah…" Atsushi responded with some shivering, "…that guy…he was my nemesis…"
"How in the actual world did he become your nemesis?" Arturo asked.
"I don't know…he just declared it on me on our first encounter."
Arturo then pulled out his small notebook and a black gel pen to take notes on Atsushi's account. "Okay, and…."
"That was about it…" Atsushi replied, "…also, how did you get out of his captivity of you?"
"Well…I had an ability known as Into the Shadows where I can blend into the shadows to hide from plain sight or sneak my way out."
Atsushi was astonished that Arturo had an ability like his.
"Yup, that one is for real, and that was how I managed to fight him off after he had found that I had escaped from his hideout."
"No way…I knew someone like him would do something bad to you…"
"Yeah, but I managed to fend him off, and tricked him, too."
Atsushi was stunned by Arturo's smartness.
"Oho-o!" Dazai said to Arturo. "Arturo-kun, you're like a fit to be like one of us…."
While Arturo couldn't think of a response, Atsushi replied to Dazai, "Um, Dazai-kun, I am not sure if Arturo would think of being one of us."
"Yeah, yeah, sorry…." Dazai digressed.
