A one-shot crossover between Re:Zero and P3. I've seen where Subaru meets the Witches, however I thought, why not put in the Messiah for a bit of heartfelt moments. Without a further a do, let us commence forth!

Makoto Yuki, felt his precense getting pulled into a distortion, another world that felt like a fantasy rpg series. He looked around but...there was only blue skies with clouds moving slowly to the keen eye. There was a table with an umbrella covering it, a few cups of tea idly sitting there with some flowers along the edge of the table.

Taking a seat, he merely looked at the tea, it gave him a very chilling vibe. While it looks like normal tea, it felt distinct, as it was created by something that was powerful. Closing his eyes, he felt a few entities in this realm. Then he felt a wave of Death wash over one of them.

Sprinting towards the wave of Death, he found 6 figures scattered over the field, a teenager in the middle that had what looks to be a tracksuit with blood spilling gushing from his wound.

"...And what the hell happened to him?" The Witches turned around, shocked that someone else had seen them and the teenager on the ground. "You aren't supposed to be here Human! This is a realm that we have created for him! And him alone!"

Pulling his Evoker out, he gave it a twirl and spun it at them. "What...is that?" "...The stench of Death is leaking from him. Why?" "It was his own doing! He didn't want to listen, and you shouldn't be here."

"..." He pulled the Evoker towards himself, once again shocking the Witches. "What in the hell are you doin-" A maniac grin formed upon him. "Persona!"

"GRAAAUUUUGH!"

A deathly screech came from behind him. A figure with a bird-shaped mask, a trench coat over it, with coffins surrounding it. A longsword in his right hand.

"Thanatos, bring him back." As commanded, Thanatos threw it's coffin at the dead teenager, encasing him in. The coffin opens again as the teenager comes back with no blood flowing from his mouth. "...Set him down while I take care these...Witches."

Standing in front of the teenager, Makoto looks at them before pulling out an orb. "None of you...are not even close to the power I wield. Perhaps...Satella is the strongest of you six."

Satella merely looked at the unconscious teenager. "Why...are you here?" "If I told you, you won't believe me. While you have the power, Return by Death, that is merely only a fraction of power of what I can do." "And is that you're familiar?" "Familiar? No. I am him and he is me. Do you know what he and I reign over?" Satella shook her head as a no. "We, reign over Death, as in the same person, we are Thanatos, God of Death. However, I am of many."

Fear, that's what it was. Death is right in front of them. One thing that every witch agreed upon was to not engage any type of God. "...Why are all of you silent?" He took out his headphones. "...So be it, I'll just wait until this young man has woken up."

An hour later....

'I thought I died? My mental state didn't want to accept anything yet...why do I feel alive?' 'So you are the one? Hm, you look pretty decent, I'm guessing you are a Japanese citizen hm? Tell me, why do you have a power of Death?' 'Who are you?' 'Someone that can give you Salvation. Those witches up there are nothing short of powerful. Except, facing a god that is. And you, Natsuki Subaru, are a wildcard. One that wasn't supposed to be here in the first place. However, it seemed Fate had other plans. Now, wake up!'

"...You are awake. Great, now let's start by the very beginning of your journey." Subaru told his story without leaving every single detail. He thought that Return by Death would've killed him right there due to the repurcutions of telling anyone his pain, trials, and grief. Makoto heard enough and shook his head in disbelief. "You have suffered so much huh? I know what's it like, loosing people who you care for. I have lost my parents and my little sister. They died by a fatal car cras- no. They died by a battle between the Supernatural and an Android. I lost a teammate of my own by the enemy, a friend who had died by complicated problems within his body. I could never stand to face the truth that they have passed. But now, I accept the fact that they had died. But you, Subaru, can reset and try again, I don't have that privilege. You are right, they might not be the same person as the past timeline you have been hopping about."

"Have you ever considered that they must have been hurting after you died in those timelines?" Subaru broke down. He finally realized the amount of suffering he had caused upon others and himself. Satella made the move of catching him. "...I only wanted to tell you to love yourself. You are worthy of being saved. So stop putting your life on the line for this type of treatment of pain!"

"It seems my part has been played. It is now time to return to the Seal. Subaru, you are a wildcard, whether you stray from the path always remember this, 'Memento Mori'. Death will always be there. But it does not judge you."

...

"I wish I saved you back then Minako...If only I was faster, you would have graduated today. Your big brother will save you in the next timeline."

Alright, first I gotta explain why I wrote this little bit here. Why yes I broke everything in Re:Zero canon but added a mix to it.

And then this part of Minako, I felt it would've given a powerful meaning. There are different timelines where everyone is not the same. Makoto would've been a great big bro for Minako or vice versa.

For all I know, I don't have that much inspiration to write that much anymore. I lost that spark. To anyone who sees this, all this means is that I'll be paying attention to my last days of Highschool. (2 months left.) If I do post an update to any story, it was prewritten before this one-shot. With that all over,

I bid adieu, flying forever FoolishAngel.
