Mha self insert character but with similar plot and different concepts of life?

Chp 3

She didn't finish he sentence but her meaning was clear. Tamaki and Mirio seemed to agree at with her but they didn't say anything.

Alice's laughter filled the room. It was a little cold and mean, but it had no intention of hurting anyone. "We'll see about that."
————
Just like that; There they were. All three of them were wearing the gym uniform with a big UA printed across their top while Alice still wore her signature red black combo. Alice stood on the opposite end of them and they stood by the door.

They stood at a gym ground with many rock columns at different heights behind Alice. Principal Nezu sat behind the students instead and watched as he sipped his hot tea.

"Ready!"
He called out in between his sips. The big 3 watched Alice carefully and she stared at them back.

"Set!"
Her finger rested by her white fang just barely piercing her. It clearly showed through her smile at them almost like warning.

"Go!"

Mirio was the first to move. It seemed like he suddenly sunk into the ground butt naked. His clothes feel down on the floor and he vanished.

'Huh? Did he just fall?' She fully cut her pointer finger and it bleed downwards on the ground. She searched around the area for him.

'Invisibility? No then he wouldn't have to take off his clothing.' Tamaki and Nejire didn't move yet. Their eyes hadn't left Alice as if waiting for a cue.

'Unless he's a ghost, no they wouldn't be waiting then....WAIT THAT MEANS." She turned around and Mirio jumped from the ground. He smiled and aimed a fist at Alice.

She put her hands up and closed her bloodied hand. It glowed gold on her  leather gloves and a certain portal sent his arm behind her. Mirio fell through and trampled on the other side before falling through the ground again.

'I missed?!' Mirio thought. He swam through the cement like it was water. 'I've never seen that before. Plus she has portals!'

Alice's chest had a number 10 on it. Luckily before the fight started and they were changing in the bathroom, Alice took her sharp metal pen and etched the word portal 1 front and portal 2 back. The black blood from earlier filled the crevices and it worked that way.

The wording was bad and a lot were up to interpretation but having some emergency trick to her sleeve. After all she needed to learn 3 different quirks while they only had 1.

She looked around but Nejire and Tamaki has disappeared from view. They took Mirio's distraction and hid from her. 'Heh, clever. They didn't train for nothing.'

'Well I'm not stupid either!' She jumped back and ran into the large collection of stones right before a blast of energy hit her.

Alice looked at and saw Nejire floating up in the sky. Alice smiled and continued to ran throw the maze of stone. "Energy waves? Noted."

Taking Mirio's idea into count, she teleported herself farther ahead on top of a random rock wall and to another one like a weird game of hit the mole. Nejire quickly lost sight of her admits the jumping.

Once she thought she'd lost Nejire's sight, Alice turned a corner but revived a blow. Tamaki stood in front of her and his armed transformed into the weird tentacle that wrapped around her arm.

'Shit! If he didn't miss I would've lost!' She jumped back and pulled on his tentacles. It jolted him forward and he lost his balance for a second so Alice could draw blood. Tamaki resisted and held her in place as best he could but make another arm reaching for her.

Another portal drawn by Alice sent it backwards at Tamaki instead. He let go of Alice to block himself with an oyster shell not knowing it was his own.

Alice took the chance and dashed away. 'Ok so ghost-like, energy waves, and the ability to turn body parts into different animals.' She ran for a while before hiding behind a column. She glanced both sides but couldn't see them anywhere.

"Shit- I don't even have their weakness.." she mumbled to herself and thought of a plan the best she could. "Unless..."
———

"Did you see her?" Tamaki ran up to Nejire and Mirio who only covered his bottom half with pants. They continued forward finding her.

"Yeah, her quirk is portals." Mirio said. He glanced around the large gym continuously. "How did she beat you guys?"

"My attack got sent back to my face."
"She ran away before I could catch up."
"It looks like she has at least a little experience in fighting." Mirio said. Although it was kind of obvious now. Tamaki stopped and looked above of himself.

"Amajiki?" Nejire stopped and so did Mirio. They looked up and saw her feet running away.

"She's there."
