Alright, after reading spoilers for the latest episodes, I decided to write something about Ashura and Eri. (with a bit of spoilers for the final battle and ending)

Part of this is a deleted scene from UA's School Festival arc, where the Six Stars chase down Deku to retrieve Yamatou. (to put in some spoilers, Deku claimed the sword from Yasha during the Forest Training Camp arc when the League Of Villains' Vanguard Action Squad struck.)

Ashura had seen him, the new master of Yamatou, wielding the noble sword with grace and agility, in a way Yasha could never. Ashura clenched both fists, feeling Shuratou quivering inside. Ashura hushed her gently. Flaming green wings burned proudly in the darkness, making the green-haired, freckled boy look even more heroic than he already was that Ashura couldn't help but wonder if what Yasha told him was true.

Yasha told me that he is demon-spawn and shouldn't exist...

"Go, Deku! Kick his...um...butt!" screamed a little white-haired, horned girl. Ashura walked over to her and asked "Um...hello?"

"Oh, hewwo!" squealed the girl. "I'm Eri! Who awe you?"

"I'm Ashura." he replied. "What are you doing here?"

"Just watching Deku put on a show." Eri laughed, and it sounded like bells ringing. Ashura couldn't help but feel sorry for the little girl, she had no idea this was a real, actual fight. Right now, Yasha had to put up against the little thief who had taken his sword with a simple katana. Even with Karura and Souma backing him up, the boy was way too much for the three of them to handle. But the whole deal made Eri happy, and her smiling face was too precious. So Ashura decided to just take a seat next to Eri.

LATER...

"Yasha said he needed me." said Ashura. "He said that I wasn't a bad omen, that I wasn't the cause of all those horrible things."

Eri smiled even more brightly and happily at this statement. "The same thing happened to me." she said. "Aww my life, I thought my quiwk was a cuwse but Deku towd me that it was a gift."

Ashura hugged Eri and they both laughed as the boy—Deku—brought Yamatou down. Within seconds, it was all over. "Yaaaaaaaayyy!" Eri screamed, and the lights went out. Afterwards, Eri had dragged Ashura all over the place, showing him lots of beautiful things. When it was time for the grand finale, Eri bought Ashura a bouquet of beautiful flowers.

"Why?" Ashura asked. "You can't do this to a person you just met."

"I don't know...but we have a wot in common, I wanna be fwiends with you." smiled Eri.

Ashura could feel his heart thumping uncharacteristically loud in his throat. "Well...umm...great...thanks." he managed to say. Seeing Eri smile like this, he never felt more affection towards anyone, not even Yasha. From far away, he could hear a man's voice, saying it was time to fire up something called a PHLASER.

His powers were stripped away effortlessly. Black Ashura stared, wide-eyed, at his arch-nemesis, the one destined to save the universe from the destruction he would bring. Shuratou fell from his hands, now no better than a kitchen knife.

"This is for Naga." Izuku Midoriya declared, directing the flames towards Black Ashura. And at that moment, everything came crashing back. Memories of his time with Yasha, every minute and second they spent together.

"Yasha...I believe you. If you say you need me, I'll live for you."

"I'll live only for you..."

And...her.

"Um...hello?"

"Why?"

'You can't do this to a person you just met."

"Well...umm...great...thanks."

"Ashura!" Yasha called out from a distance, but Ashura wasn't listening. His mind was fixed on her.

Eri...Eri...

All he could think of was her as the flames that used to be his own engulfed him.

He met her again at the party celebrating the crowning of the Yasha clan's new king. That boy managed to get the crown after all, but for some STRANGE reason, Yasha seemed cool with it. Ashura, however, was not. He was having some alone time in the furthest corners of Zenmi Castle when he saw her again, lost and lonesome. "Pretty..." she murmured as she walked over to him.

He scooped her into his arms and asked "Eri! What are you doing here?"

"Who awe you?" asked Eri. "How'd you know my name?" Ashura was a bit surprised, but since he had regained his true self, it was no wonder that Eri didn't recognize him.

So he just smiled, and declared "Eri, you might not believe it, but it's me, Ashura. Why I look like this is actually..."

Just then, a bright white light engulfed them both. And it wasn't caused by Eri's quirk this time, no.

And neither of them knew no more.
