The students saw a beautiful woman passing by. 

Student: Whoa! Who is she? 

Student 2: For shame! She's Ms. Ririko, the Math Teacher! 

Student 3: She's so sexy! I wish she could teach me some things! 

Ririko Kagome (The Match Teacher of Yokai Academy! She's very, very passionate about math!) 

In Math Class... 

Ririko: And then if you take alpha times beta from this solution, the coefficient of X squared is this, based on equation A. If we take this to the next step, we can see that this is an easy way to remember a convenient solution as well as a good way to understand the relation of coefficients. (Y/N), do you think you can solve it? 

(Y/N): Sure! This is going to be easy! 

You solved the problem very quickly! 

Ririko: Yes, that's very good! You're so skilled at math! I will say the of end-of-term test will be easy for you! 

(Y/N): Yeah, I bet. 

???: Oh, I think you'll do well, (Y/N). 

(Y/N): HUH?! 

You saw someone behind you. 

Mizore Shirayuki (A Yuki-Onna who attends Yokai Academy! She has been stalking you for quite a while! Voiced by Tia Ballard!) 

(Y/N): Uh ... who are you? 

Mizore: I'm Mizore Shirayuki. You're my favorite. 

She was licking the lollipop in her mouth seductively. 

(Y/N): Oh ... uh ... thanks. 

Much later... 

You were talking with Mizore. 

Mizore: I barely stood out, because well ... I'm a massive fan of yours. 

(Y/N): You ... are. 

Mizore: I read all that you wrote in the school's newspaper. I even made a scrapbook out of all that you wrote. 

(Y/N): Oh, that's very thoughtful of- 

You saw her scrapbook! 

(Y/N): Okay, she's definitely a Yandere! 

Mizore: Ha ha ... what do you think? I wrote a lot about what I thought of the paper. 

(Y/N): Oh, that's nice. 

Mizore: I'm usually a loner, but meeting someone like you was important to me. 

After school... 

The girls caught on quickly. 

Yukari: Yeah, it seems that (Y/N) is being stalked by another girl in his class. Stalkers are creepy. During the last semester, there was a girl who proposed to a teacher that she liked, and after he declined, she turned him into ice. 

Kurumu: How crazy. But what do you think of this? I made these cookies for (Y/N) that we'll share after the semester is over! 

Yukari: Well, they look nice, for your standards. You can be more ruthless than a stalker. 

Back with you... 

You watched as Mizore was throwing stones that skipped across the water. 

Mizore: That was 9 times, did you see (Y/N)? 

(Y/N): Yeah, uh ... Mizore, I have this little thing I have to get to. I think I'm going to- 

But she hugged you. 

Mizore: Come on! It's your turn, (Y/N)! 

(Y/N): Really, I have to study and- 

Mizore: You're going to meet with Moka Akashiya, right? Please don't. If you do, I don't know what I'll do to her. I don't like her. 

(Y/N): H-Huh? 

Mizore: You belong only to me. 

Meanwhile... 

Moka: Where is (Y/N)? It's not like him to show up so late. 

???: Sorry, even if you wait, he won't come. 

Mizore appeared. 

Moka: YOU! You're- 

Mizore: You were watching us, right, Moka Akashiya? Tell me, what are you to (Y/N)? 

She grabbed Moka by the neck! 

Moka: AGH! 

Mizore: You're an eyesore. If you're not around, (Y/N) will be mine! Even when I'm around, all he can think about are girls like you, it really pisses me off. I can't forgi- 

Moka: STOP IT! 

She slapped her, and- 

Mizore Clone: Too bad, this is just an ice puppet, the real me is with (Y/N). 

Moka: What? 

The clone of Mizore formed her arm into an ice spike and impaled Moka with it! 

Back with you... 

(Y/N): CRAP! The water froze! 

Mizore: I won't let you get away from me. 

(Y/N): Mizore, I understand you like me, but I- 

You noticed all the ice surrounding you. 

Mizore: (Y/N), I won't let you leave me! 

(Y/N): You're the only human, and I'm the only Yuki Onna here; we understand each other. You're the only one, so please be mine, (Y/N). 

(Y/N): Look, Mizore, I can accept you, but the truth is, I have a- 

Moka: (Y/N)! 

Moka came in with Kurumu carrying her. 

Mizore: What? My clone should have killed you by now. 

Kurumu: Yeah, well my great instinct helped Moka at the last minute! Your puppet should be in pieces by now! 

Mizore: STAY OUT OF MY WAY!

She unleashed ice on the girls! 

(Y/N): MOKA! KURUMU! 

They crashed into you, with their boobs going into your face! 

(Y/N): AGH! Lovely! 

Mizore: Dumbass. 

Mizore stood over Moka. 

Mizore: Why would I give my (Y/N) to an eyesore like you. I'll kill you, and- 

(Y/N): MIZORE! IF YOU KILL MOKA, I'LL HATE YOU FOREVER! 

Mizore soon went flatlined at that, and collapsed. 

(Y/N): Whew, that was close. Sorry about that. 

Moka: (Y/N), how did you- 

(Y/N): Girls who are totally in love with me, will usually get like that when I say those words. But she should be fine. 

You picked her up. 

(Y/N): She just wants someone to appreciate her. Well- 

You kissed her on the forehead. 

(Y/N): I'll give her all the attention she needs. 

Mizore blushed as you did that. 

Mizore: Ah, (Y/N).
