Prologue

Makoto Naegi, 20 years old. Kyoko Kirigiri, 20 years old.

Both graduated from Hope's Peak Academy, they live together in a small apartment and are fiancés. They work together as detectives/investigators to solve different cases and others. They are happy together, nothing is wrong in their lives, just some wishes for the future that they know that together, they will accomplish.

But…

One day…

"Dinner's ready!" exclaimed Makoto from the kitchen.

"I'll be right there." Answered Kyoko in the living room, her laptop on her lap, and as she was about to stand up, she received an email. "Hm?" She opened it and started reading. "Interesting…"

"What is it?" asked the brunette, entering the living room with two plates of spaghetti Bolognese.

"We just received a tip… from an anonymous. Look: "

From: 10260110756
To: ultdetectiveduo
Subject: TIP / Illegal Activity at Murkoff Psychiatric Systems

You don't know me. Have to make this quick. They might be monitoring.

I did 2 weeks of software consult at MURKOFF Psychiatric Systems' facilities in Mount Massive. All sorts of NDA's I am very much breaking right now but seriously, fuck those guys.

Terrible things happening there. Don't understand it. Don't believe half the things I saw. Doctors talking about dream therapy going too deep, finding something that had been waiting for them in the mountain. People are being hurt and Murkoff is making money.

It needs to be exposed.

"This looks serious… But wait. Mount Massive, Murkoff? Aren't those wh-" started Makoto but his girlfriend beat him to the punch.

"Mount Massive Asylum, shut down amid scandal and government secrecy in 1971, reopened by Murkoff Psychiatric Systems in 2009 under the guise of a charitable organization. The Murkoff Corporation has a long track record of disguising profit as charity. Whatever they thought they could get out of this place has to be big." She put a finger under her shin and started thinking a bit. "It might be dangerous… Do we take it?"

"To solve a mystery, you sometimes need to take risks. Isn't that right?" he grinned as he put the plates and the dishes on the table, he joined the detective on the couch.

She smiled back, "how dare you use my own words against myself? Is that a yes?" she asked after jokingly punching his shoulder.

"Of course" he responded pressing his lips against hers.

The next evening

Kyoko was driving their car on the muddy and hunchbacked road, the car shaking every meter traveled. Mount Massive Asylum was situated in the middle of nowhere. A perfect place to hide any kind of strange and illegal activities… The couple were listening to the radio while driving, Kyoko at the steering wheel while Makoto was checking the email that they've printed and checking on the camcorder and batteries. Suddenly the radio cut off abruptly. They stared at each other and some seconds later, they arrived to the front gates of the Asylum, next to it, a sign saying:

Mount Massive Asylum

"Well, that's not welcoming at all…" Kyoko said, looking through the windshield, Makoto sharing her reactions and gulped at the sight.

The building was gigantic and very creepy looking, like a manor in a horror movie, plus the sunset illuminating the building from behind gave the building a very dangerous vibe. The detective asked her fiancé if he got everything ready. His response was positive as he took out his notebook and a pen from his pocket and handed it to her. He took the camcorder, checking again if it worked, the zoom… check. The night vision… check. Everything was good.

"Alright let's do this." She firmly said, getting out of the car.

"Yes!" answered the ahoge boy. Once both out, they stared at their new destination. They didn't notice the gate closing behind them as they were focusing on their new case: to uncover the mysteries of Murkoff's illegal activities at Mount Massive Asylum.

They slammed the car's doors.

Danganronpa X Outlast

Survival at Mount Massive Asylum

So here's the new crossover I'm working on.
But a quick question: Should I replace the other character in outlast (Chris Walker, Billy Hope, Dr Trager, father Martin) by some characters from Danganronpa 1? Or should I just leave Naegi and Kirigiri live the nightmare?
