Izuku: Who are you?

?????: Allow us to introduce ourselves, my name is Venti!

???????: My name is Zhongli, young one.

??: I am the Raiden Shogun, but you can just call me Ei

??????: You can call me Nahida.

Izuku: Those names are... familiar...wait, I know! You four are the Legendary Archons!

Ei: Oh? So people these days are still familiar with archons?

Izuku: Well, not quite. Your time is deep in the books.

Zhongli: Figures!

Izuku: And they are.... "Points the Harbingers"

?????????:  Oh, where're my manners? My name is Tartaglia, my real name is Ajax but you can call me Childe.

?? ???????: Call me La Signora.

Izuku: And they are....  "Points the Abyss Twins"

??????: Aether, Abyss Prince.

??????: Lumine, Abyss Princess.

Izuku: It's nice to meet you.

Aether: Thanks! Oh, by the way! 

Aether knees izuku in the gut making him drop to his knees. Izuku looked at him in pain wondering why he did that 

Aether: "Yells in anger" WHAT THE GODDAMN HELL IS WRONG WITH YOU! ARE YOU SO WEAK THAT YOU JUST LET THOSE PUNY HUMANS OUT THERE PUSH YOU AROUND!

Izuku: You don't understand!

Lumine: "Yells in anger" I UNDERSTAND EVERYTHING! I SAW EVERYTHING FROM INSIDE YOUR HEAD. YOU LOST YOU FATHER, WE GET IT! WE EVEN HAD TO WATCH OUR ENTIRE CIVILIZATION PERISH ON ONE NIGHT!

Aether: Now, stand up!

Izuku: Huh?

Nahida: We will cut to the chase...to put it simple, we have been looking for a successor, as we Archons have died a long time ago, and right now, we're simply spirits, and we have been looking for someone to use our powers.

(Archons are not immortal, for your information)

Venti: And after a little bit of searching, we found you, and we deem you worthy of using our powers!

Izuku: Huh?

Tartaglia: You are the perfect one, being discriminated for your whole life, and yet, you preserved and stayed strong, we deem you worthy...but the question is...do you accept?

Izuku: "Thought" With these powers...I won't be useless...and I can help people...and I can...even protect Itsuka! I will prove All Might, my ex-mom and all those assholes that doubted me wrong and show that I can be a hero.

Izuku: Yes I accept! 

Venti: Great! You will be blessed with the powers of Anemo...

Zhongli: Geo!

Ei: Electro!

Nahida: Dendro!

Tartaglia: Hydro!

La Signora: Pyro and Cryo!

(A/N: The Pyro Archon, Hydro Archon, and the Cryo Archon weren't released in the game, so I let Tartaglia teach Izuku about Hydro and La Signora taught Izuku about Cryo and Pyro.)

Aether+Lumine: By the power of the Abyss! I! Aether The Abyss Prince!/Lumine The Abyss Princess! I choose Izuku Midoriya as the heir to the power of the Abyss!

Venti: We will train you slowly, as it isn't easy to wield all Seven visions at once.

Aether and Lumine instantly teleported them all to a suitable place to train Izuku.

Aether: A massive underground city constructed by an ancient civilization long gone. To this day, the purpose of this underground city remains unknown. Its structure is divided into the "Abyss Corridor," which connects worlds, and the "Abyssal Moon Spire," which leads to the unknown. It is now collectively called the "Spiral Abyss"... It is said that many secrets and treasures that have been long forgotten by this world lay buried within... Monsters and humans alike flock to the tower in search of the secrets and treasures it contains. Challenge different floors of the tower and defeat the enemies within to win Abyssal Stars. 

Lumine: At the first 8 floors here, the Archons and Harbingers will train you and will teach you the most basic things about elemental skills and how to use weapons and forge one.

Aether: On the 9th floor onwards, we will train you in how to use the power of the Abyss.

Izuku: So how long are we gonna be in here?

Lumine: About 1000 years!

Izuku: "Yells" ARE YOU INSANE I WILL BE WAY TOO OLD!

La Signora: "Chuckles" Relax kid. A year in this place is only 1 minute in the real world. So considering the real time, it will take you about 16 hours.

Izuku: Thanks, everyone!

Izuku headed towards the portal to the real world. His instructors stood in the distance and waved goodbye. Nahida is crying because she doesn't want Izuku to go but they're still in Izuku's head.
