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

congrats it's a chapter...yay....

The blood was dark as ink and with a couple of scribbles in the air, the blood turned to gold. A black portal appears with another one in front of the redhead and the balls teleported straight into the trap.

"huh?!" It hit 2 of the buttons on Black widow's shoulder and leg but the last one missed. Black widow jumped away from the portal on another step. "What's this?!"

"My quirk's portals, dumbass!" Alice's voice grew hoarse as she grinned evilly up at Widow. Her finger slowly bled with a few drops of black blood rolling down her hand. In front of her chest glowed an icosahedron with a number 14 in the middle of it.

Black widow untied her web of string and aimed all of them at Alice in a panic. Instead of fear, Alice smiled and drew similar squiggles in the air. Again they turned to gold and sent her to the stairs alongside Widow, this time with a number 17.

"Behind you!" Alice teased. Clearly panicked, black widow countered the attack and created a web of string between them. Her foot slipped to the end of the step with a few stone pieces falling to the ground of the endless abyss.

"W-who are you?!" She stuttered on her words, glaring at the wall of webbing. Her arms were crossed at her face. "I have never seen you before!"
"Who are you?"
"B-black Widow duh!" 
"Takahashi Sakura. Age 15. Quirk Micro-psychokinesis and you lived with your father for most of your life because you lost your mother in a car accident as a child."
"H-how? I've never told anyone that before!"
"Your character bio of course!" One the other side, Alice opened a profile similar to hers, but with Sakura's information. On it lists many other links and files that have more info about her, even some she didn't know.

"I can show you if you let this web down." Alice stood on the other side patiently and clam, but Sakura was sweating bullets. The web was so thick you couldn't see anything on the other side, but if you pressed on it, it would have a little bit of ease.

"No! I'm not an idiot!" The web seemed to tighten, losing the elasticity of it. Alice audibly sighed and her soft laugh echoed in the empty stairway. Sakura tensed up. Her eyes fixed on the creep who knew her information.

"I know who killed your mother Sakura."

Her words stung like a bullet straight to her chest. It sunk deep into her head it made her slightly dizzy. "S-shut up idiot like I'm gonna believe that!"

"Your mother has hair like yours. Pretty young when she had you too. She took care of you even after the divorce and loved you." It was like Alice was reading a perfect script of her life.

"SHUT UP SHUT UP!!" Sakura screamed at her, rejecting the idea. She unweaved her web and threw the needles directly at Alice with one big whosh.

Alice's still slowly bleeding right hand scribbled in the air. Like a planned defeat, Sakura lost all her Needles and thread to Alice's black portal. Once they entered the portal chommed on them and cut the thin string. She tried to call them back yet there was nothing.

As the feeling of defeat set in, Sakura dropped to the ground looking at her hands with the ends wrapped around them. Her whole body trembled and she collapsed sitting in a W.

Alice looked down at her, emotionless and calm. Her finger slowly started to heal itself and her chest had a perfect glowing 20. Alice bent down with an orange ball in her hand and clicked her last button on her stomach.

"How?" Sakura's voice was weak and frail. Her eyes glued to the gray floor. "How did you..."

"I summon portals anywhere as long as I know it exists, I simply threw your little needles next to the sun and burnt them to a crisp." Alice smiled a little and sat down with her. Her number and blood seemed to disappear into her body. All the blood that was once there absorbed into her skin.

"No, I meant my family..."

"You're father lost custody over you, Sakura, whom he'd loved so much. Then the stress of business came, the loss of a family he loved, and losing most of his earnings, he grew depressed." She rubbed her back slowly to comfort her. Sakura stayed quiet and was still listening to her.

"Drinking didn't help, he found no fun trying to meet new people, and all day long he yearned for you. In the end he went crazy and decided to get you back. How? An Accident."

"On the winter day before you and your mom were supposed to visit your dad, he unscrewed the wheels to the car. Just partly so your mother would slip in the snow and crash."

"He got away with it and you lived with him as the parent. Yet he regrets it. After all he loved your mother, you, every memory you guys had together. He mourned her even till this day, but he wanted you to be happy. "

"Your father got back on his feet and started to take work more seriously. Now he can afford to raise you until your 40. He apologizes to your mother everyday and wishes all that well for you."

"He wanted you to be the hero you always were to him. He supported you through School and training didn't he?" Alice stared at the tears rolling down Sakura's cheeks. The child looked helpless and sorrowful it hurt to even be near her.

"Ugh- fine." Alice carefully hugged her around her arms. Sakura seemed to warm up a bit. "It's okay. It's okay. You had to know one day."

"Please head to the Main entrance and remove your buttons. All losers should head to the lounge." The buttons on their clothes talked. Sakura giggled a little and stood up. Her back faced Alice and she calmly fixed her clothes and tied the loose strings to her belt.

"Great! I know something new today!" She faked clearing her throat. "But I'm going to keep smiling! Just like all Might!"

"Isn't that what mom and dad would have wanted?" She turned back with a smile. Her eyes and nose were still a little puffy from the crying and her sleeves dirtied themselves.

"Duh dumbass!"
