Enemies (Yandere-chan X Nemesis-kun) (Yansim; Creepypasta crossover)

Chap 1: I will kill you!

The rain is pouring onto the ground. In the cold air, there is a sound... of a girl, crying for her love, her love is lying on the ground, cold and lifeless... The assassin in a black suit stands up, he looks at her with soulless, empty eyes... The girl looks up... her eyes is filled with rage. "How dare you! You maniac! He is everything to me! How dare you, taking him away from me! He is mine! I will kill you!" She takes out her knife and attacks the assassin. The assassin speak calmly while dodging her knife: "My mission you to stop the yandere bloodline." The girl keeps swinging the knife to him, she yells: "Shut up! Shut up! You killed him! You killed him!"

The assassin catches her arm and pushes her back. She fell on the ground, the knife falls out of her hands... The assassin looks at her again, then he leaves. As he came out of sight, the girl picks up the knife, with a soulless, emotionless voice, she says: "My mother will be very disappointed in me... I'm coming, my love..." She raised the knife above her chest, as she was about to stab herself, a bullet hits her hands, hurting, she dropped the knife. Then she hears a familiar voice behind her: "I won't let you die, for now. If you want revenge, come to me when you are strong enough."

The school girl turns around, she looks at him with hatred. He turns around and says: "That's all I have to say. I'll take my leave." She sits there, unmoving for a moment. She then, looks at the sky, she smiles, bloodthirst is in her eyes, she says: "If he is not alive, no one can! Including that assassin!" But let leave that for tomorrow, she cleaned up the evidence and bring her beloved body home, putting it on her bed. She looks at him every three seconds, cherish his face, and when she is in bed, hugging his body, she set up a plan... "I'll do it for you, beloved..."

She went to school 30 minutes early, the teachers also go to school 30 minutes earlier to prepare for the lecture. She planned to kill half of them (3) in this period of time because she will kill the other 3 at lunch time in the teacher room, she isn't strong enough to not let four adults pin her down, so the number of teachers must be lower than that, but students can't pin her down. The teachers were alone in the classroom so it's easy to kill them from behind. It took her thirty minutes to dispose of the body and the evidence, the gym teacher and the delinquents didn't come yet that time.

The gym teacher and the students came to school, after all students, including the delinquents left the school gate, she killed her. In her clothes, there are keys of the gate and all rooms in the school. "How convenient." She thought. She closes and locks the gate to avoid students running out of the school. In this school - a strict school, students don't have access to telegraph in the school so the students will not be able to call anyone without stepping out of the school. (Author note: sorry for breaking some of the game mechanics.)

She changed her clothes and hind the body and the knife in one rubbish bag to past the delinquents. The delinquents don't care if it's cleaning time or not so they don't stop her, after that, she cleaned up the blood. She went to class like an innocent student. There are no substitute teacher until tomorrow, so one teacher teaches two classes, the school is wondering why 3 teachers didn't come to class...

Lunch time, she locked the teachers in the room with her, and she stab them to death... The delinquents are not near the infirmary at lunch time, she disposed of the body easily. At the end of lunch time, two of the delinquents are in the male restroom while the other three is heading to the infirmary. She heads to the male restroom and kill two first, then she goes to the infirmary to kill three of them. The students are all in class now so they won't see her, except for the student council. She sneak in the hallway to dispose of they body and clean up their blood. Near the infirmary, she let out a laugh to recover sanity.

Now the student council, she already killed Megami, her last rival last week. The security system is removed because she is very careful not to left any evidence, only two of her rival are killed by her own hands, including Megami so the headmaster was not that suspicious, but the main reason is, without Megami, the security system is not really needed. And the guidance counselor lost her job at this school because she didn't succeed in 'fixing' the delinquents after 9 weeks like she promised. How ever, the 'missing' of Megami really alarmed the other members of the student council so she has to be very careful to kill them.

She killed there of them, only Shiromi is left... She is disposing Akane's body, the only body left... but as she gets closer to the infirmary, Shiromi appeared. Shiromi was about to pepper spray her, but the Yandere girl quickly get away. "Where is she now?" Shiromi thought, then that girl appeared right behind Shiromi's back and stab her. She cleaned up the evidence. The Yandere successfully eliminates the student council.

The next part the worry is the headmaster, how will she kill him? He has an electric gun... She decided to look for the situation first, she sneak into the headmaster's room expecting to find the headmaster. But... he is not there, he is not around school, where might he be? She found a piece of paper on the desk, there are bloodstains on it. There are words on it, it says: "To the daughter of Yandere, the headmaster is dead, you won't find him. The Saikou family got rid of him, he keeps too much information. - Nemesis." "So he is dead..." She thought: "In these kind of situation, his actions are quite... useful. But he will be dead under my hands not long from now... Senpai, I will do anything for you..."

She took out matches for her pocket and burn the paper. "Now, Info-chan and the normal students is left..." She thinks, grips the knife tightly: "I will kill her quickly, the normal students are not that much of an thread..."
