Author's notes: I was so hyped about Yanderedev's newest video and had to write this. I'll try to put out another chapter soon!

INTRODUCTION: PART I

Ayano Aishi hummed in satisfaction as she left the school. She'd gotten some work done today, and tomorrow her scheme would result in Megami Saiko's, her most challenging rival's yet, final elimination. She was almost certain that after she'd dispose of her, her beloved Senpai would finally be ready to fall in love with her.

She recalled her first rival, Osana Najimi. Ayano smiled to herself. She'd made the right choice. She was never very rash, or impulsive, and so when Osana first stood in her way, she chose to be rational about disposing of her and started looking for valuable allies. Info-chan wasn't much help in her quest for Senpai's affection, and taking pantyshots for her as payment for favors prooved... troublesome. So she began searching among other students.

The naive, but strong martial artists seemed easy enough to manipulate, but they weren't as skilled in combat as she originally thought and using them could become difficult and require a lot of skillful manipulation. Some students were popular, which would give her a lot of connections throughout the school, but weak and hard to use for her goals. Others seemed valuable at first, but prooved useless as she examined them more carefully.

When she met the delinquents for the first time, she immidiately saw how much they could benefit her. They were quite capable fighters, and frequently broke the school's rules so it wouldn't be too difficult to convince them to help her. She picked a random member of the group and over the course of a few days did everything she could to help him and please him. Eventually, he decided to do something to pay her back... but not the way she expected him to. Instead, he contacter someone who prooved much more useful than any student at school.

And that was when she met the man she knew only as ''Yakuza".

He was part of a criminal organization and offered to do a favor for her in return for helping his younger brother. Without much hesitation, she stroke a deal with him, and Osana was gone the next day. She never learned how or when extacly he did it, and who helped him, but one thing was for certain – he got the job done.

The next time Ayano enountered a rival, she didn't hesitate to contact Yakuza. This time, however, he requested to be paid in exchange for the favor. And the currency was unusual, to say the least... He demanded kidnapped victims.

Three students – that was how much it cost her to eliminate Amai Odayaka. She was lucky to find a few loners who happened to be wandering around the school on their own, completely unprotected. She then transported their bodies to the Yakuza and it was only a matter of time before Amai ''disappeared" mysteriously.

The method prooved simple enough and once she mastered it, it became both the quickest and safest option for her. She couldn't risk getting exposed or arrested by experimenting with different ways of eliminating her competition, and Yakuza always handled the kidnappings expertly. She was eliminating her rivals, and he was provided with kidnapped victims without any dirty work. They both benefitted greatly from the deal.

However with each elimination, the prices grew higher. Three, five, seven, ten bodies... But it was only a minor inconvienience for her... until now.

When Yakuza heard the name "Megami Saiko", he immidiately told her that it wouldn't be as easy as the previous ones – and thus, more expensive. She knew Megami was well protected at all times by body guards hired by her insanely rich father. Besides, her family was one of the mostinfluential in the whole Japan. If Megami was kidnapped, everyone would know about it, and the risk of the kidnappers getting exposed grew even further. That was why he requested thirty two students in exchange for kidnapping her.

She knew she couldn't kidnap more than twenty students over the course of a single week – she'd already tested her limit with Hanako, and was nearly arrested because of her clumsiness. She couldn't risk kidnapping one third of the school's population without drawing attention to herself – it was way too dangerous. So without thinking much, she decided to kill Megami herself, for the first time getting involved with her rival.

She knew Megami had no weaknesses. She was always around large groups of people, and even when she wasn't, she had bodyguards. If, by some miracle Ayano managed to catch her alone, her self-defense skills made her much stronger than her, as she was raised to be prepared for absolutely everything. Befriending her was out of question either, as Megami was very cautious of strangers and never paid much attention to students as unimportant as Ayano. The only option left for her was blackmail.

Yesterday, she left a note in her rival's locker. It was an annonymous threat. She wrote that if Megami were to appear at school the next day, she would kill her. The threat was obviously fake, since she couldn't just kill Megami. But she hoped the girl would be too scared to come to school until the end of the week. And she was right.

The entirety of the day, her rival was nowhere to be seen at school. Ayano assumed she took her threat seriously.

Given her current situation, it was understandable that she was very much proud of herself after today. Her smile brithened at the thought of tomorrow... She would leave a note in Senpai's locker, telling him to meet her by the cherry tree behind the school... She'd already memorized what she wanted to tell him, practised it so many times. He would kiss her and tell her he loved her as well... Oh, how long she'd been dreaming about that day-!

She kept thinking about tomorrow's events for the rest of the day and when the night came, she jumpedinto her bed, the happiest she'd ever been and had dreams of Senpai's and hers life together...
