After Monokuma revealed the true identity of his agent, who was Oogami Sakura, the other started hating her and after Fukawa called her "a brutal murderer without any sense of what's right or wrong" something in the mind of Asahina finally snapped.

After everyone left their meeting place, which was the cafeteria, she followed her fellow student with the two long pigtails until she saw how Fukawa opened her door to her room. At that moment she took the chance and pushed her into the room. Before Asahina closed the door by herself she also entered the room and sealed it that way. Fukawa was confused and scared at the same time, but before she could scream for help Asahina held her hand in front of her mouth. That way it was impossible for her to scream or even say something. "You said Oogami has no sense for right or wrong? Well... I know what is right and what is wrong and what you said back there was unforgivable wrong! Now you'll feel sorry for yourself because you chose the wrong words as you last ones!", she whispered while she sat down on the breast of Fukawa, pinning her arms down with her knees. Tears were filling the eyes of the Ultimate Writing Prodigy as she saw how her fellow friend pulled something out of one of the pockets of her red and white jacket. It seemed to be a longer rope, which was all curled up. Before Asahina could uncurl the rope she had to pull her hand back, but to avoid that her helpless victim could scream for help she dropped the rope next to her and pulled something out of her other pocket. It was a role of duck-tape, which she took out of the supply room in the first floor. In a quick movement she held it onto her own mouth and bit on the gray tape, pulling some of it loose from the tape underneath it. Then she let her teeth go of the gray object and held it next to the covered mouth of the crying girl. Fast she pulled back her covering hand and placed the ending of the duck-tape closely next to the mouth. With one move she pulled it to the left and finally sealed the mouth of her helpless class member. Now she had both hands available for her upcoming kill. She took the rope back into her hand and used both of her hands to uncurl it in ten-seconds-flat. Fukawa had no choice and stopped struggling,on the one hand because she knew she had no chance and on the other hand because her arms got tired. With an evil grin on her face Asahina bound one of the endings around the neck of the pigtailed girl and gently pulled on it to make it perfectly tight. "Funny right?", she asked as she took one of the ends in each hand and grope them very tightly. Fukawa looked with wet eyes into the mat and dark eyes of the Ultimate swimmer, which were usually shiny and blue as an ocean in the summer-sun. "You decided for yourself that Ooshina is a murderer... But I am the person who decided over your fate! And with the next pull I'll make sure you won't hurt her again! Never again!", she almost screamed as she pulled both of the endings into opposite directions. That way she made the grip around Fukawas neck even tighter and finally destroyed any chances of her to breath the fresh air, which kept her alive. The struggling began again, but this time Asahina could feel how the power and might Fukawa putted behind each thrust deceased over the time... After 8 seconds Fukawas movement stopped, but her eyes were still sending out water and her voice could still be heard but it was more of a coughing underneath the duck-tape. Out of joy and to humiliate her the Ultimate Swimmer, or would the Ultimate Sadomasochist be more perfect for her in the current situation, tore of the gray material and pain began to travel through her victims body. Now Asahina heard the gasping sounds and the quiet, cracking words "Wh-why... Asa...na...hel...". After another four seconds the Ultimate Writing Prodigy was no more. Her face was grayish blue and her eyes were lifeless and one last tear streamed down her right cheek. Asahina lifted herself up and then took a chair and placed it underneath a free spot in the ceiling. She climbed on top of it and reached up into the air. She took the last item she brought out of her pocket, in which the duck-tape was lying before. It was a metal hook, which she rammed into the hard ceiling and with the help of an thick, purple book, which she took before she stepped on top of the chair, she made sure that this hook won't get torn out. She stepped of the chair and putted the book back onto the desk, then she lifted up the dead body of Fukawa and seconds later she tried to fiddle the rope trough the hook. After a double-knot her former friend hung in the room, moving slightly to the left and to the right. Asahina went to the desk and ripped out the last page of an empty cobybook and wrote in her most gorgeous and cleanest handwriting a farewell letter. She signed as Fukawa and left the room with a quiet yet sadistic giggle.

In the class trial everyone was pretty sure that Oogami killed Fukawa. She was the strongest one who was still alive after-all, which was the main reason why everyone suggested her as the true culprit. Asahina was the first one who got eliminated as the culprit. "She is too small and weak to win against her in a fight. And she surely could have never lifted Fukawa up to the ceiling!", Naegi threw his thoughts into the room and, after a short period of silence, everyone agreed. "They are truly dumb...", the Ultimate Swimmer thought to herself and tried hard to keep herself from laughing or even giggling, "Vote for anyone you want! It won't change a thing. And when this trial is over I'll kill the next one who ever dares calling my best friend a killer!" Kirigiri explained how the whole scenario must have went and she almost got everything right: "First Oogami followed Fukawa and entered her room alongside her. That's the only chance because the door was unharmed. Then she attacked her and used something to prevent her from screaming. Most likely it was some kind of tape or something else but she surely prevented her from screaming for help. Then she took the rope and bound it around her neck and, with her strength, pulled it to choke her to death. After that she attached the hook to ceiling and lifted the death body up. She may not be tall enough so she most likely used the chair, which was standing in front of the hanging body. After she finally attached the rope she wrote the farewell letter and left the room." Everyone imaged the scene in their minds and, without any doubt, agreed to this explanation. "So, are we ready to vote? I think we are!", Hagakure asked and Naegi nodded. Monokuma, who was quiet the whole trial, finally said something and reminded everyone: "If you vote correctly, that person will be executed. But if you vote wrong everyone else will be executed. The culprit will stay alive!" A shocked mime appeared on the face of Asahina and she remembered, that everyone else will die if they chose Oogami... and that meant: Oogami would also die! "Wait!", Asahina screamed, which left everyone in shock and surprise, "Don't vote for Sakura!" Kirigiri took a look at the sweating and red face of the Ultimate Swimmer and asked her: "Why not?" Asahina gulped and finally explained: "She... She isn't the killer... I am! I Killed Fukawa! I choke her with a rope and sealed her mouth with duck-tape. After that I attached the metal hook into the ceiling and hit it multiple times with a book. Then I hanged her and wrote that stupid letter! I am the killer! But she deserved it! She deserved this a hundred of times! How could she dare and call my best friend a killer... It wasn't her fault everyone died... It wasn't her fault... But Fukawas death was her own fault! Her actions were the reason why she just HAD to die!" Asahina screamed as loud as she could and finally sank to her knees crying. But not because she felt bad or she felt ashamed of her actions, she cried because she had to go through the whole scenario before she killed the pigtailed girl with the glasses. "You're the culprit?", Oogami asked and Asahina looked at her with her wet eyes and nodded silent. A small smile appeared on the face of the Ultimate Martial Artist and she began to cry. "You all did that for me? Because she called me a murderer and I'm your best friend?", she continued her question-parade and the kneeing girl nodded again alongside her words: "Yeah, I couldn't stand the whole situation. You aren't guilty in any kind but still she called you that devilish name! Unacceptable!" Slowly Oogami walked over to her fellow friend and helped her onto her feet and putted her into a tight cuddle! "Thank you for your help... but I am a strong person with a strong personalty and such words can't hurt me... Sorry that this all have to end like this... Best friend...", the white haired girl explained and Asahina began to cry again. She knew she was right, she knew it. "Please vote now! Or everyone will be executed!", Monokuma ordered and Asahina loosed the cuddle. "Go and vote for me... And promise me you will survive!", the brown haired girl whispered with a light and cracked voice. "I promise...", Oogami answered and went back to her place. After a short amount of time the voting was finished and Asahina was the "winner". "Goodbye dear friends... Goodbye Oogami...", the Ultimate Swimmer said and wove with her hands to say goodbye to everyone. Monokuma pulled out his hammer and... Oh you know what he did.

Asahina is in a box, which is moving, and suddenly she fall a long way until she finally hits the ground... or should I say the water. With a loud "SPLASH" she dives into the blue liquid and, out of surprise and fear, swims back to the water surface, gasping for air. Slowly she looks around, but there is nothing special around her, nothing else then water. But suddenly a loud sound can be heard behind her and as she turns around the volume of it grows. Finally she can see what it really is and shock decorates her wet and throbbing face. A giant boat propeller appeared out of nowhere but something seems strange. The blades aren't normal at all! They are knife blades and sharp as hell! "Oh no...", Asahina thinks to herself and slowly backs up, moving her feet and arms to create a farther distance between the propeller and herself. Then it happens: The object starts spinning and it comes closer! No wait, it sucks the water towards him, that's for sure. The only way for Asahina to escape is to swim as fast as she can and she ever did. Without thinking or wasting any second she starts moving her feet as fast as she can and performs her favourite swimming style: breast swimming. But no can do because the blades won't back off which terrifies the Ultimate Swimmer. Now she uses her full amount of energy and not even the fastest speed boat could catch up with her. And the boat propeller can't either as it backs up more and more until... "BAMM" Asahina hits something hard in front of her. Scared and in panic she tries to figure out what she just hit and in a short amount of time she figures it out. A mirroring wall is in front of her and on the left and right side. The giant ocean is just an ongoing reflection, but something is wrong with it... She is missing in every reflection! As if she isn't real or something! But the blades are real and they are slowly getting closer to her and without any chance of escaping her death she just waits. Seconds later the propeller reaches the end of the waterway and slices Asahina in little pieces. Suddenly the propeller gets pulled out of the water and the whole thing reveals itself as a little tube which belongs to Monokuma, who is laughing while he watches his spinning propeller, which slowly stops spinning.

Between two of the blades a read piece of clothing can be seen... It is the red knee-pad which was tied around Asahinas knee.
