Overdrive: A MHA x Male Reader Fanfic

Can't think of a title lol

I should mention that if you see bold text at the beginning or end of chapters or in (parenthesis), then it's an author's note. If it's in "quotations", then influential people are talking.

You kick open the door to Chisaki's place. The other heroes fall in afterward. You eventually make it to a little depression in the wall with a vase there. Sir Nighteye stops.

"This is it. There is a device here that opens a hidden passage," he said. He removed the vase and pushed down on specific tiles. "You press down on the floorboards in a specific order, and then..."

The secret door then opened. The Hassaikai members ran out. Centipeder and Bubble Girl quickly took care of them. They restrained them and told us to move on without them. The group soon ran down the flight of stairs and into the passageway. We quickly come to a dead end. 

"Hold on, I'll take a look at it," Mirio said.

"No need," Red Robin responded. "To sum it up quickly, my quirk can give me a quick display of various subjects and tell me their status. That wall is thin and weak, and the hallway continues on the other side."

You, Deku, and Kirishima went to destroy the wall; however, only you destroyed it. You got to it first. You all continued running when the whole place began moving around. You are shocked a little but focus on the mission. You hear Lemillion say something behind you.

"Besides, this is just a stopgap! They can warp the path forward if they want, but as long as we know the direction of our goal, I can still reach it!" Lemillion said with determination.

"I'll come too!" you say. "Speed is key, and they know it! Me and Lemillion can get there faster, and we can quickly deal with anyone in our way!"

"It's why they are stalling for time. We are going ahead! Ready Overdrive?" Lemillion asks.

"Born ready," you respond and start running with him. You two quickly reach a wall. Lemillion phases through it, and you are about to brute force your way in when time slows down.

"Are you seriously just going to brute force your way in? Use your Super-Speed to phase," An unknown voice behind you says. You turn around.

"Oh, it's you. Primus was it? Why are you here? And why isn't my mom here? She usually is when you are here," you ask.

"Yes, I am Primus. Your mother is in a different universe training. I think she's been declared Victus now," Primus says.

"What?" you ask, confused.

"The audience will find out later... maybe. Anyway, I'm here to help you," Primus says.

"Why would I want that? And didn't you say you won't help me anymore? Wait, didn't you also try to kill me?" You ask.

"So many questions, so little time-"

"Time is literally frozen. What do you mean?"

"Shut up, don't interrupt me. You wanna know how to phase or not? I'll do it for you once; remember that feeling," Primus says.

Time resumes, and you try to move, only to stay completely still. Suddenly, your body begins to vibrate. You can still feel your body and what it's experiencing. You can feel how fast you're vibrating. Your body then begins to run through the wall, similar to Lemillion. You quickly catch up to Lemillion and feel yourself in control of your body again. Lemillion sees that.

"Woah! How'd you phase through that? Did you copy my quirk or something?" he asks

"Advanced and theoretical physics. I can vibrate to match the vibration of the molecules of other objects, allowing me to go through them," you quickly explain. "I should also mention that my brother, Saiko, is here. He might be with other league members, but it's too late to turn back now."
