Before the story starts, there are a few things you should know about this story.

One, This is a My Hero Academia and Arcane: League of Legends crossover.

Two, there will be a LOT of Arcane spoilers so read at your own risk.

Three, Shinsou, Vi, and Powder/Jinx are all siblings with Shinsou being the youngest and Powder being about two years older than him. Bakugou is also Mylo's younger brother with him being about five years younger than Mylo (I couldn't find Mylo's canon age so let's say he was about fifteen years old). And Midoriya is Ekko's younger brother by about three years.

So, basically, before the time jump, Shinsou, Midoriya, and Bakugou were ten, Powder was twelve, Ekko was thirteen, and Vi, Mylo, and Claggor were fifteen. After the time jump, I'm going to say it was about six years later. That being said, Shinsou, Midoriya, and Bakugou are sixteen, Powder (Now known as Jinx) is eighteen, Ekko is nineteen, and Vi is twenty-two. Mylo and Claggor aren't included after the time jump for obvious reasons.

Bakugou, Shinsou, and Midoriya all grew up in the Undercity together. Shinsou's parents were killed by enforcers and was adopted with his older siblings by Vander. Bakugou was born in the Undercity. Mitsuki and Masaru were all great friends with Vander and helped him around in the Last Drop. Izuku and Ekko were abandoned by their parents when Ekko was five and Midoriya was three. Not too long after, They were found by Vander's good friend, Benzo. Benzo took Ekko and Midoriya in and cared for them.

Four, After the failed rescue with Vander, Midoriya, Shinsou, and Bakugou all escaped and thought everyone else died. They ran off to go find Bakugou's parents since they were all they had left. Mitsuki thought it'd be a good idea to leave the Undercity to keep the kids safe from Silco. They left and started a new life in Japan. Mitsuki was the legal guardian of Midoriya now but Shinsou was adopted by two pro-heroes by the names of Eraserhead and Present Mic, also known as Shota Aizawa and Hizashi Yamada. Thankfully, Aizawa and Yamada didn't separate the three children, and since they lived really close to Mitsuki and Masaru, Shinsou was allowed to visit whenever he wanted. The children and Bakugou's parents decided to keep their past in the Undercity a secret since it was such a sensitive topic for them.

Five, This story will have TodoBaku, KiriDeku, and ShinKami present.

Six, Izuku was born with a quirk called Dragon Spirit. It's basically a combination of his birth parent's Telekinesis and Fire Breathing quirk. He can breathe fire from his mouth like his father but his mother's telekinetic quirk only enhanced his strength. So he basically had super strength and a fire-breathing quirk.

Seven, This story takes place after Vi and Caitlyn reunited with Ekko but before they went topside with the Hextech Gemstone. The story will continue from there and a few things may be changed.

Eight, Hitoshi, Izuku, and Katsuki's relationship is strictly platonic. They cuddle, hold hands, kiss each other on the head and/or cheek, stuff like that as comfort for each other. They have a brotherly bond, them seeing each other as siblings. Nothing is romantic with those three.

Nine, it is VERY rare for Zaunites to be born with a quirk so the three children kept their quirks a secret outside their family. The only people who know about their quirks are Vander, Vi, Powder, Ekko, Benzo, Claggor, and Mylo. Also, most topsiders have quirks so in this story, Caitlyn's quirk is called Crossfire. Basically it enhances her aim and tracking ability which is perfect for her job as an enforcer.

I think that is all the big parts. You will get a larger backstory later on. Now without further ado, Enjoy!
