Riku surprised as he heard what his twin brother said. Not even one minute, he asked, "Wh-Why, Tenn-nii?"

Tenn sighed, "Nee," he turned his eyes to Iori, "Is it okay for me to visit Takanashi Headquarter? I have something to talk about there."

Someone approached them—it's Banri. He controlled his breath once he arrived near them and a few seconds later, he said, "You guys are insane just like me when I was a bit younger."

Meeting Room, Takanashi Headquarter.

9 PM.

All of IDOLiSH7 members are gathering there. Before we continue let me describe the meeting room. The room is contain two sofas facing each other with a table between them. There are stacked chairs at the corner of the room. And for the rest of it, feel free to imagine how the meeting room is.

Riku, Sogo, Yamato and Mitsuki are sitting on the sofas while Iori stand leaning against the wall also Tamaki is sitting on the floor (between the sofas). They are talking about their mission today and tried to solve the problem. They are in a serious talk since 7 PM. Ah, I forgot to tell you what they were doing before they meet. They were investigating Yaotome Production and asking people around the company also the employees. Everything is okay except the building and Yaotome Sousuke' disappearance. Even until the investigation done, they didn't find out the reason of Sousuke' disappearance.

A lot of holograms came out from the table and papers strewn around it.

"Okay, let's make a conclusion, what we get from our investigation," said Yamato.

"Oh, Yama-san! I want to make one!" Tamaki suddenly turned excited, "Etto... The yokais destroyed Yaotome Production because they want to bring back something important that the Production' took at the first place."

Sogo continue Tamaki' sentence, "'Something important' is probably Kujo Tenn, TRIGGER' Center."

"The reason of Yaotome Sousuke' disappearance is still unknown," Mitsuki sighed, "Although we have asked Yaotome Gaku and Tsunashi Ryuunosuke, they didn't know."

"Oh? How about Kujo Tenn?" asked Nagi.

Riku shooked his head, "Tenn-nii didn't know too."

"He said there's something that he wants to talk about with us. I wonder what it is," said Iori.

Yamato sighed, "I hope we can get something from what he said later. Aaaghh," He scratches behind of his head hardly, "Although we have spent a lot of time, only these that we've got?!"

"We only got two conclusion, huh?" Sogo held his chin.

Mitsuki turned his eyes to one of the holograms, "Oh, TRIGGER."

The rest of i7 turned their eyes to the hologram.

"It's rebroadcast, huh?" Iori approached the hologram.

"But, it seems they shoot this today. Cuz', they were asked about the incident," said Yamato.

"Sugoi, TRIGGER. Although it's hard for them, they are answering the questions professionally," said Tamaki in awe.

"Tenn-nii..."

Not long after, someone knocked the door. "Come in," replied Yamato.

"Excuse me. Sorry, I'm late," the one who knocked came in and closed the door.

"Tenn-nii!"

"Riku," Tenn smiled. And then, he approached i7, "You guys are still investigating the incident, huh?"

"Well, yeah. Since it's our job," answered Tamaki.

"So, Ku—I mean, Nanase-san. What do you want to talk about?"

All of the i7 members except Iori and Riku surprised. Tenn turned his eyes to Riku and sadness radiated from his face. He closed his eyes and take a deep breath—seems it's hard for him to tell the 'story'. He opened his eyes and begin to talk, "Riku, you realized what happened to you, right?"

Riku widened his eyes and turned sad. He lowered his head and nodded. "Have you talk about it with your friends?" Riku shook his head as an answer.

"What's wrong, Riku-kun?"

Riku doesn't answer. "Jaa, is it okay for me to tell them? Since it's seems hard for you."

A few seconds later, Riku agreed. Yamato sighed, "For now, Kujo. Please take a sit beside Riku."

After Tenn sat, he told i7 members about everything that the author tell on Chapter 10. After 30 minutes, Tenn finished his story. No one react to it for a while. Iori finally opened his mouth, "Do you have a pict of Kujo Takamasa?"

"I have," Tenn picked his phone from his pocket and press some of buttons on the screen, "Here," he showed his phone to Iori.

After Iori saw a picture of Takamasa, he sat on the ground (across from Tamaki). He press some button on the hologram—he searched for Kujo Takamasa' information. After he found it, he surprised. The rest of i7 members and Tenn turned curious because of Iori' reaction. "What's wrong, Iori?" asked Mitsuki. Iori swipe the hologram and the hologram divide into eight, each of them are facing each person in the room. All of them surprised after they saw the information.

"Deceased?!" said Tamaki. "Souka... I understand," said Sogo.

"What is it, Sogo?" asked Nagi. Sogo answered, "He is an AI with two personalities. Why an AI? Because, he has steel skeleton. About the two personalities, one of it is Kujo Takamasa' real personality and the other one is someone that Kujo-san called 'monster'."

"I'm not Kujo anymore. Besides, I'm originally Nanase Tenn. By the way, what is AI?" Tenn tilt his head.

"It's Artificial Inteligent, Tenn-nii. A robot with human appearance. Usually, they are stronger than humans and the purpose of making it is to be used as a weapon of war."

"Usually, only the secret group from government who owns it such as Takanashi Headquarter or something that related to military. Which means..." Yamato didn't continue his words.

"...is someone from the government that made Kujo Takamasa AI," continue Mitsuki, "Iori, try to find the cause of his death."

Iori nodded and pressed some buttons on the hologram. After a few seconds, Iori shook his head, "Unknown."

"Nee, Iorin, try to search information about Maroru Sajou Park," said Tamaki. Iori quiet for a second and finally he realized something, "Souka! 'Maroru Sajou is a short of three names, Kujou Takamasa, Zero and Sakura Haruki.' It might be has something related to Kujo Takamasa' death."

When Iori pressed some buttons on the hologram, Tenn surprised, "Zero? Isn't he an idol? The legendary one. Sakura Haruki is the composer of his song."

The i7 members widened their eyes. "I-Idol?" asked Mitsuki. Tenn nodded, "And Kujo-san is the producer."

"What the hack? Why were they made an orphanage and did a yokai experiment?" asked Nagi.

"Found it!" said Iori, "'Maroru Sajou Park is an orphanage which was built by Zero, the legendary idol, Sakura Haruki, his composer and Kujo Takamasa, his producer. They want to help—" suddenly Iori stop reading.

"Why don't you continue, Iori?" asked Riku.

Iori sighed, "The web only describe what Maroru Sajou Park is."

"What are we going to do now?" asked Yamato.

"Matte," Sogo opened his mouth, "Tamaki-kun was escape from there and President saved him, right? I think, President must has the report about it."

"Oh! You're right! So-chan, you are genius!" Tamaki stood up and left the meeting room. "Matte, Tamaki-kun!" Sogo followed Tamaki.

After MEZZO" left, Tenn asked, "What are you guys talking about?"

Yamato laughed awkwardly, "Seems we have to explain it to you."

"Isn't that danger?" asked Iori.

"Well, Ku—Aaaghh, do you mind if I call you Tenn? Since it's hard to determine which Nanase is it."

"I don't mind, Kamado Yaito-san."

Mitsuki held his laugh and patted Yamato' shoulder, "Ossan..."

"Kamado Yaito?" Riku thought for a sec, "Ah, it's Yamato-san' disguise name, huh?"

"Eh?" Tenn surprised.

"Nana...se....Ri.....ku...-san....!!!" Iori rebuke Riku.

"Ah, yabai," Riku held his mouth, not long after he said, "But, I think is okay to tell Tenn-nii. Since he has involved with this."

"Disguise?" Tenn thought for a sec, "Ah, sou... I get it. I knew it is weird from the start. Three securities joined our company and one week later they were fired together. Ono Kensho and Eguchi Takuya stop visited the company too..."

Tenn smirked, "Seems you guys aren't too pro yet, huh?"

"You have to be more polite with the seniors here, Tenn," said Yamato.

"But, he's right, Ossan," said Mitsuki with face palm.

"Well, maa..." Yamato fixed his glasses nervously.

Iori sighed, "That's why I said to not stop together at the same time."

Riku smile awkwardly, "Maa, I'm glad only Tenn-nii that realized it."

Tenn sighed, "Now, introduce your true identity."

"Izumi Iori desu."

"N-Nikaido Yamato desu."

"Oh, damn, Ossan being played by a brat. Ah, Izumi Mitsuki desu."

"Nagi Valhart von Northmeir desu."

"N-Nagi..." Riku laughed awkwardly.

"Ah, gomen... This guy is still wondering that he is a second prince of Northmeir. His real name is Rokuya Nagi," said Mitsuki.

"WHATTTTT?!?! BUT I'M THE REAL DEAL, MITSOOKI!!! I HAVE TOLD YOU GUYS, RIGHT?!"

"But, we're in Japan now! Use your Japan name!"

Iori sighed. Yamato laughed. Riku laughed awkwardly also sweat drop. Tenn face palm.

Not long after, Tenn turned his eyes to Riku and stared at him for a long time. Riku realized it and decided to ask, "What's wrong, Tenn-nii?"

"You are Ono Kensho, right?"

Riku smiled and nodded, "Yeah."

Tenn stayed quiet for a while and then said, "I'm glad. You're not hate me. You are miss me, right?"

"Sasuga, Tenn-nii! I'm glad too, that you didn't abandon me and really love me."

Tenn smiled, "You are still cheerful as always, Riku."

Riku laughed.

Not long after, MEZZO" came back. "Yosh, we got the info!" said Tamaki excitedly. Sogo laughed, "I'm glad you managed to get the info."

"Woah, is that a compliment?"

Sogo nodded.

"Yatta! I'm being praised by So-chan!"

Tenn looked confusedly at MEZZO". "Ah, he is Osaka Sogo-san and the blue one is Yotsuba Tamaki-kun," explain Riku—seems he knows what his twin thinking.

"So, what did you get, Yotsuba-san?"

Tamaki sat where he sat before he left and said, "So, etto..." He opened the document, "According to this report, after several years Maroru Sajou Park was established, something happened. The three developers were being attack by an illegal group. The boss of the illegal group taking over the orphanage."

"The boss, huh...?" said Mitsuki. "Ah, I think I know who is the boss," said Iori.

Tamaki continue his words, "Kujo Takamasa has a deal with the boss of the illegal group before Maroru Sajou Park established. Takamasa needed some money to build the orphanage and to fulfill his entertainment job. The boss agreed if Takamasa give everything important to him as a return. That time, Takamasa doesn't know what is important for him so the boss said that he will search it for Takamasa. After three years, the boss knew all of important things in Takamasa' eyes so, he decided to take it all. He killed Takamasa' friend, Sakura Haruki but he failed to kill Zero. Zero managed to escape and after that, he disappeared. The boss took the orphanage, his life even the boy that Takamasa took interest on him, Nanase Tenn."

A minute of silence~

"The conclusion is the boss of the illegal group is..." Iori didn't finish his words.

"...Tsukumo Ryo," said Riku to continue Iori' words, "He might be the mastermind of today's tragedy."

"You said that because the yokai wanted to bring Tenn to the boss, right?" asked Yamato. Riku nodded as answer.

"We also can conclude that one of the AI personality that live with Tenn-kun for last five years is Tsukumo Ryo," said Sogo.

i7 (except Sogo) and Tenn widened their eyes. "Because of him, there's a monster in Riku," said Tenn sadly. Not long after he clenched his hands, "I'll never forgive him."

Riku lowered his head and turned sad. After a minute of silence, Nagi opened his mouth, "Why Tsukumo destroyed Yaotome Production then?"

Yamato sighed, "Seems we've got another new mystery."

Mitsuki said, "Two mysteries has solved. Mysteries that haven't solved yet are what 'Angra Mangiu' is, Yaotome Sousuke' disappearance and the reason why Tsukumo destroyed Yaotome Production, huh?"

"Don't forget to include how we get 'Angra Mangiu' out from Nanase-san," Iori added.

Tenn held his chin, "How could 'Angra Mangiu' got into Riku's body?"

"As I recall from what I and Yotsuba-san got when we went Maroru Sajou Park, 'Angra Mangiu' is a shadow-shaped person and it needs a human vessel. So, obviously he can easily get into Nanase-san' body."

"But, when?" asked Riku.

"Well, when you said that there's someone approached you when you were in the burning house beside President."

"But, I told you, right? It's a man not shadow-shaped person."

Everyone there except Riku surprised.

A moment of silence~

Sogo opened his mouth, "There's two possibilities. First, the man that has possessed by an Angra Mangiu died and because it lost it vessel, it moved to Riku-kun. Second, because Angra Mangiu is a shadow, he can easily change his appearance."

"Maybe, we can took the second possibility. Since, I've talked to it mentally last night."

Everyone there except Riku surprised again.

"Y-You talk to it?!" asked Mitsuki.

"Why did you say that?" asked Nagi.

"Angra Mangiu took same appearance as me when we talked. Eh, matte..." Riku thought for a sec an opened his mouth again, "But, I saw blood came out from the man' body back then..."

Everyone sighed. "Yare, yare, it's totally complicated," said Yamato while fixing his glasses' position.
