Sakura Ogami, the Ultimate Martial Artist: Sakura Kombat IV: Bloodlust

This case follows the story until Genocide Jack attacks Aoi in the dining room.

Sakura, who realized that her best friend was attacked because her attacker was too afraid to fight her one on one, felt a fire sparking in her body she never felt before. Pure anger! She tried to leave the Ultimate Swimmer with Makoto but before she had the chance to leave the nurse's office Asahina tried to talk some sense into her.
"Sakura, please... Don't harm her. I'm okay..."
The giant woman heard her friend sobbing and agreed to only talk to Toko and don't hurt her in any way.

That evening she ran into Toko in the library , where she was watching Byakuya for almost an hour before he left and ordered her to tidy up the place. She was doing what he told her and placed the books he read back in the shelves until she heard the voice of the muscular female, who entered the room.
"Toko... I need to talk to you", Sakura tried to start a conversation but the second she finished her sentence a book flew towards her but that was no match for her.
She fended off the flying object with a quick punch, which tore the book apart. Toko began to scream and throws one book after the other but every book either missed her target or was destroyed before it even reached her. She ran away and got cornered by her, in her eyes, enemy and she desperately tried her best to win the fight she started. She then took a very old book and threw it towards Sakura. Not even one second later the same book crashed into the shelf to Toko's left, causing a big smoke of dust to surround her. And then it happened: She sneezed.
Before the opaque smoke disappeared the world-famous serial killer dahsed towards Sakura with her scissors in her hand. She usually only targets boys but this was an exception. Her life and, more importantly, maybe even Master Byakuya's was in danger! She couldn't let her escape.
She buried her scissors in the chest of the larger woman and jumped back to her old location, taking new scissors from her hiding spot, her socks. But Sakura stood calm and pulled them out with ease, causing even more blood to leave her body.
"Please... I just want to talk to you...", she tried again to explain her reason for coming here but Genocide Jack wouldn't listen. Instead of doing that she continued her attack on her, causing more and more stab-wounds until the Ultimate Martial Artist caught her wrists and held her in place.
"Now... let's... talk... o-"
"I will kill you! I will kill you for being a threat to master Byakuya and then I will kill the little guppy for smacking my master! You and her will di-", Genocide Jack interrupted her but she couldn't finish her sentence either.
Before she had the chance to do that Sakura snapped and tossed her headfirst across the room with as much force as she can offer, destroying one giant bookshelf in the process. She turned around and saw what she had done, causing her to calm down immediately. Genocide Jack was lying in the broken remaining of the wooden bookshelf, her body covered in cuts and bruises and her neck was twisted violently. There was no way of denying it: She killed her classmate.

The school trial went on very quickly and everyone was sure that Sakura killed Toko because no one else could cause so much destruction. The only person who was not convinced was Aoi Asahina. She believed the promise her best friend gave her and there was no way she would ever break one.
"Sakura can't be the killer! She just can't! Toko had her scissors in her hand so she must've switched with Genocide Jack and she would never attack or kill other women! She said it herself! It must have been either Byakuya, Makoto or Hiro!"
Her voice proved to everyone how desperate she was. She knew she was wrong but she doesn't want to believe.
"But Hina... She attacked you too...", Makoto cuts through her argument like a hot knife cuts through butter.
It was over, she had nothing left to say and Sakura never tried to deny it herself.
"Please... Sakura would never-"
"I did it", a voice echoed through the courtroom.
Sakura admitted her crime, the trial was over. The culprit took off the mask. Hina stared at her friend as tears formed in her eyes.
"No... no...", were the only words she had the chance to form before Monokuma started the voting.
The results: five votes for Sakura Ogami and one vote for Aoi Asahina. Hina voted for herself.
"I... it was my fault all this happened... If I hadn't had smacked that jerk..."
"No...", Sakura tried to comfort her by placing her giant hand on Hina's head and striking her hair, "I lied to all of you and I was the one who lost control... Toko was scared and I knew that..."
More tears ran down the swimmer's cheek and Sakura couldn't stop her tears either.
"Aw... What a tragedy...", the annoying bear's voice ruined the moment completely after appearing between them and wiping away tears that don't exist.
"Buuuuuuut we need to get this over with soooo", he rushed back to his podium and grabs his hammer, "It's puuuuuunishment Tiiiiiime!"
"Noooooooooooo!", Asahina screams as the execution begins.

Sakura is standing in a dark alley. Only two street lights are on and no other person or even animal can be seen or heard. Suddenly a group of six Monokuma's rush towards her from different sides but she easily fights them off. The vision turns into a 2-d sidescroller and Ogami makes her way from the left side of the screen to the right, running in more and more Monokumas. Some are fighting her with fists, some of them use baseball bats and a few of them use Molotov cocktails. Her health bar slowly decreases but she easily defeats all of her enemies until a big Monokuma, called Ookiikuma, enters the screen. He has his own health bar and they start to fight. Sakura seems to be winning but before she can make her final attack the screen freezes and Sakura can't move anymore. Someone paused the game but only her part of the game. Ookiikuma begins to attack her with fire-fists, ice-fists and small missiles until her health bar only has 2% left. He performs his Fatality-Move and flies into space and then drops down to earth like a big, burning meteor. He lands on Sakura and a red text on the screen says:

Winner: Ookiikuma!
Executed: Sakura Ogami
