Author's note:

Hello, I'm a newbie who had just joined this fanfiction writing community a couple of weeks ago.

I had just recently fall down the deep hole called "IDOLiSH7's fandom" and I can't get out, so, this is the result of that fall. A crossover that I think no one really need but did it anyway. And I admit, I'm not patience enough to write everything from the start, so I glossed over many things. So to understand what is happening in this fanfic, knowledge about the anime IDOLiSH7 and Log Horizon is required. I bet that there are still many grammatical errors up there, so if you can point it out for me I'll be very thankful.

P.S: And I'm not gonna be able to update regularly, because writer's block is a pain… maybe every 3 weeks to once a month…or more depend on my inspirations and the amount of homework and deadlines in school…

CHAPTER 1

IDOLiSH7 still remembered that day vividly. It was several days before their first outdoor concert (their first ever concert even). Their manager had given them 3 months to become familiar with each other and later, with their new dorm, although of course they still keep their reason to be an idol secret (well except Mitsuki and Tamaki who will say if asked). They had even learned to adjust themselves to ease some of Riku's burden, worried for his health (even if said center didn't like it).

And then that day, all except Riku went out to either work or study. They all met on the way back and decided to go together when the news on the screen on the sides of the buildings was interrupted by the breaking news of thousands of people all over the world went missing in their own home at the same time. Their similarity is that all of the missing people were sitting before their computer, waiting for the launch of Elder Tales' upgrade version - the game is very famous with 13 servers worldwide (three of which were in Japan) and was having its 10-year-anniversary. Nagi then had a horrified expression on his face.

"Nagi, what's wrong?" Mitsuki asked worriedly

"I just remembered, Riku said that he has been playing Elder Tale since it first launched, and he's staying home to wait for the upgrade today!" Nagi said in panic while jumbling in his English-Japanese way of speaking

"Then we should hurry back!" Iori had already started running, prompting the others to go after him

The six of them got back in record time and started running to Riku's room right away, hoping to see their cheerful center. However, what greeted them was an empty room, with the computer still on, the screen with the letters 'CONGRATULATION' flashing in different color under Elder tales' logo. Everything started to get worse and worse, the remaining six member began to have more and more disagreements and fights. Riku was the glue that kept them together, even if the red head didn't know it. They didn't want to believe that their center, their friend was gone, along with thousands of other people without them knowing whether he is still alive.

Their turning point had been when they were deciding their group name. Originally most of them want 'IDOLiSH7' as their group's name, but without Riku the name seemed wrong in some way. That was until Tamaki surprisingly became the voice of reason.

"Nee, can we still have that name? I don't want it to change" the light blue haired male said thoughtfully

"Tamaki? Why..?" Sougo asked in surprise

"Even if we don't know where Rikkun is...we don't know if he's even alive either...But it also means that someday Rikkun may come back right? I'm not saying we leave that center spot alone, I just think that Rikkun is still one of us and he still want to be an idol" Tamaki said while eating his pudding and ignoring the others' gazes

"Yes! I agree with Tamaki-kun on this! Riku is still here in our heart, and we will carry on his dream with this name!" Nagi said excitedly

"Don't talk like Riku is dead, you idiot!" Mitsuki yelled in anger, then said softly "He's not..."

"I wonder if Riku is angry with our behavior this past week...will he lecture us or will he try to force us to eat his super bitter dish as punnishment?" Sougo smiled sheepishly while trying to imagine their center's face

"Maa, we will make up for this by performing our first outdoor concert to the best of our abilities" Yamato said to the group

"OU!"

Thanks to this, their concert was a success even though there were only 9 people watching. Time flied by quickly, first came their 2 months ban, then TRIGGER's live, at which Yamato, Tamaki and Nagi met Kujou Tenn, who was about to collapse from exhaustion, and helped him getting to the venue. After that was being accused of trying to steal TRIGGER's fan after the live, while the truth is that they felt too restless seeing the star group performing. Then the debuting of MEZZO, which consist of Tamaki and Sougo. Going to Okinawa to make their first MV for the new song, and meeting TRIGGER again at the same place. Their own song being stolen by TRIGGER's composer, their first failed performance at MusicFesta, their own self-made channel to interact with fans. Yamato's first acting in a movie, Tamaki's disastrous reality show which led to Sougo collapsing and admitted about his family situation. And their nomination for JIMA Newcomer Award.

The six of them sometimes went into Riku's room to tell their stories. There were times when they came in together and told their stories, inserted with their own thoughts, and there were times some of them went in alone when things got too much. It's a way for them to cope with the stress of becoming an idol, their own circumstances and the empty feeling they got when Riku disappeared. They didn't touch anything in the room other than cleaning occasionally, "for when Rikkun come back" said Tamaki. They wanted to pretend that Riku was still there, that he can still hear them. That the red-haired center would listen to their problem without any negative expression like he used to, he would encourage them whenever they feel down, he would make Tamaki his favorite pudding, cook with Mitsuki and Sougo, wautch Magical Kokona with Nagi, tutor Iori and Tamaki,... President Takanashi, Banri and Tsumugi was worried, but even they can't fault the members for this because even they were affected by this. Without Riku, it felt like every thing became a little duller, a little colder.

None of them noticed the silver flute sitting on Riku's night-stand shining a little whenever someone came in the room.
