A Rush Of Blood (BNHA/MHA OC)

Ichor

Hisoka dodged a punch from Fukuda, the latter grinning as she continued to swing at her.

"Finally! I was getting tired of you just being a living punching bag!" The woman said, stepping back.

Hisoka sighed, glancing at her phone.

"Ah, hold on. I've gotta take this." She said, answering the call from Izuku. "What's up, Izuku?"

"Could you stop by All Might's office?" The boy asked, sounding uneasy.

"Okay?"

"Now, actually. We um.... We found something."

*One hour later....*

"You called?" Hisoka said, entering the room.

"Yes, young Chihara." All Might responded.

Next to him was a hero (Gran Torino if she remembered correctly), Izuku sitting across from them.

"Sounded urgent." Hisoka commented, sitting down.

"Well...." Izuku trailed off.

"You're about to get some sensitive information, kid." Gran Torino said bluntly. "Means you can't go yapping about it, not even to your little boyfriend!"

*A few minutes later....*

".... Okay then. That explains a few things." Hisoka said, still reeling from the information she just received.

"Yes. Now that you know about One For All, young Chihara, we can get started.... You see, recently we've been doing more research on All For One and One For All." All Might explained.

"I found this when poking around on the internet. A weird legend of some sort.... But you know how legends are, right?" Izuku said.

"However, it's in a mix of Japanese, English, and Spanish." Gran Torino said. "Midoriya said that you're an expert in all three."

Hisoka shrugged. Izuku pulled up the information on a laptop, sliding it over to her.

Long ago, there were the brothers, All For One and One For All.

Both brothers fought constantly. However.... There was another quirk that could rival that of All For One himself. A quirk's that rivaled both brothers, in fact:

CRIMSON ICHOR.

This was something that she, the Crimson Lady, knew well, so....

The goddess of blood had a child, passing on the quirk she treasured so dearly and all its potential.

In order to keep this great power sealed, she separated her body and spirit.

One, was locked away in a Crimson Coffin.

The other, was left with her descendents' quirks.

But....

All For One and One For All both desired this power.

Legend says that he, the Demon Lord, found the body of the Lady.

No-one has found the spirit....
