Before everything else:

In another town near Morioh, known as Kuoh, a man of French origin is currently walking around a park. It's currently early 2017.

You may know his father as Jean Pierre Polnareff, but this man, is named, Thomas Guillaume Polnareff.

He isn't a stranger to the supernatural phenomenon that is, stands. He has witnessed many events, even the battle between Yoshikage Kira, and Josuke Higashikata.

After the battle, Polnareff has been educated about the existence of stands, with the help of Hayato Kawajiri, and Jotaro Kujo himself.

A while later, he awakens his stand, having inherited similar abilities to his father.

That was a thing that happened 10 years ago, right now, Polnareff's about to learn more about the world of the supernatural, a lot more.

While walking around the park, Polnareff saw one of his classmates and acquaintances, Issei Hyoudou. Issei for him is kind of like the perverted friend that you have, he's the one who's the most likely to crack a perverted joke or something around that area.

Being a pervert, which is a well known fact across the school, has prevented Issei, and his friends, who are collectively known as the 'Pervert Trio', to lay their hands on any person of opposite gender, whatsoever, which is their goal basically as perverts.

Which shocked Polnareff, because what's happening right now, is that, Issei is with a girl!

So what he was saying about a new girlfriend during class wasn't bullshit… Polnareff thought.

The next thing that happened, is that the girl suddenly transformed into a being with edgy clothing along with black wings, which is also known as a fallen angel. None of the two know this fact yet.

Then, the girl subsequently stabbed Issei on the spot using.. bright glowing white spears, also known as light spears.

The girl would have turned to Polnareff and killed him along with Issei for being a witness, if not for the fact that he possesses a stand.

Polnareff, instead of calling for help and ringing the cops, he has decided to turn around, and ignore what just happened, as he knows that dealing with the supernatural is a pile of shit.

In a change of heart, Polnareff's body went a full 180 and sprinted to Issei's body, he examined his vital signs, checking his pulse, breathing, all those stuff.

Unfortunately, things aren't looking very good for Issei, since his vital signs are already gone.

"This man is now dead, this is a dead man beside me." Polnareff concluded, he reached for his phone to call the authorities until..

A red magical circle with details that resembled Satanism suddenly appeared from the ground near Polnareff and Issei. What came next from the circle is a familiar figure that Polnareff, and especially Issei knew.

Rias Gremory, the most popular student of the entire school, there hasn't been any known student in the school that hasn't fallen for Rias. With Polnareff, he sees her as more of a senior than anything else really.

Polnareff isn't a flirt, unlike his father.

"Oh, it looks like I was too late." Rias said looked at the corpse of Issei. Polnareff raised an eyebrow at that statement.

"Too late? What do you mean?" Polnareff asked in confusion as his eyes narrowed down on her.

"Thomas Guillaume Polnareff, the valedictorian of the class huh?" Rias recognized Polnareff. He has also quite the brains, passing through most subjects with ease. His only major difficulty is Japanese.

"Yes, I am, now tell me what's going on. You have Issei which suddenly got fucked over by a girl who suddenly transformed into some dipshit with black wings. You then have you, who suddenly teleported here using that.. magic circle thing." Polnareff's voice raised for each sentence he said.

"Calm down Polnareff, I'll explain everything to you soon afterwards. Right now, I need Issei." Rias reassured Polnareff, which didn't help all that much.

"You sound like one of the cops that just arrived to a crime scene." Polnareff said with a disagreeing tone.

"I promise this, I'll explain what's going on soon afterwards." Rias walked to Issei's side and then brought out something, a chess piece, a pawn chess piece in particular.

Okay, what's the significance of that chess piece? Or Issei really? Polnareff thought to himself.

"So you were the one who called me." Rias muttered to Issei.

The chess piece then started glowing a red light, after a few seconds the glowing chess piece disappeared from Rias' hand.

"What did you do?" Polnareff asked Rias.

"Not now, I'm bringing Issei back so I can heal him, mind if you come to the old school building tomorrow after classes? I'll explain everything to you after classes." Rias said as she carried Issei's body with her arms, another satanic circle appeared behind her.

"The Occult Research Club? Hopefully I don't turn into some ritual thing." Polnareff said.

"Don't worry, we don't do those kinds of stuff." Rias said to Polnareff.

"Oh, okay then." Polnareff said as he looked at the magic circle behind her.

"Thank you, I'll be going now." Rias turned and walked over the circle, then vanished along with Issei being carried with her arms.

And that occurrence topped the battle between Kira and Josuke as being the weirdest thing that has happened in Polnareff's life.

Polnareff slowly started walking back home, glancing to his back to the aftermath of that encounter.

Satanism.. black winged girl with glowing white spears.. A senior with devil-ish powers.. Issei dying in front of me.. must be the work of an enemy stand.. actually I don't know. Polnareff thought to himself as he tries deducing what just happened today.

He concluded that visiting the old school building tomorrow is where the answer is.

But right now, Polnareff is comparing this event to what happened in Morioh 10 years ago.

What's weirder? Highschool pervert gets fucked by a girl with black wings using light spears or, man with hand fetish gets overrun by an ambulance while fending off 2 Joestars and a few stand users?

Polnareff sighs on the way home.
