"There's something weird going on." Budo announced that lunch time. "2 students have died and another has gone missing. It can't be a coincidence."

Hina shrugged. "I don't know. Osana Chan committed suicide, bless her poor heart. Kizana was a complete accident. We were there, we saw it. No mistaking the accident. And, I don't know. Oka was always a bit strange. I'm sure she'll be back soon enough."

He shook his head. "Girls, I think we should do some training. You never know who's plotting."

Akane nodded. "Yep. Megami has us all on lookout for anyone who might hurt us or the school. But I have to say, I haven't noticed anything untoward."

"Yeah. I think if someone was behind this, they wouldn't do it under everyone's noses." Uekiya added.

Budo shook his head. "Better safe than sorry. I'd feel awful if someone is doing all this and you couldn't protect yourselves. Oka was last seen here. We don't know what happened."

Hina shook her head. "It's awful, babe, I know. I'll take some extra training, just to protect myself."

"Me as well." Uekiya said.

"Well, I'm already trained. And I have pepper spray." Akane said. "Being student council rocks."

"I'll take some lessons." Ayano said. "I've never done anything like that and you never know what might happen."

Budo nodded. "Exactly."

So, that night after school, Ayano and co attended a martial arts class.

"Okay, the main thing you want to do is make sure you can block. Blocking is twice as important as attacking. Look, if I'm coming at you with a knife, you wanna grab my wrist, twist it, and kick me, in the balls or stomach. Wanna try it?" Budo asked Ayano. She nodded.

Ayano grabbed Budo's wrist, twisting it away from her, and lightly kicked his lower stomach. He sprung backwards.

"Perfect! You've got it down! Obviously, this will only work if they're coming from the front. And you may get scratched by the weapon, but that's better than being stabbed. Once they're kicked, it's your opportunity to run. As fast as you can. Hide somewhere, go into a classroom and tell a teacher, whatever. Just do anything. Play possum if you need to."

Ayano nodded. "Right."

"Okay, sounds like you've got it."

Ayano picked up all kinds of tips from Budo. She thought about a multitude of things she could use them for.

Ayano watched as a new young woman entered the school. She was tall, voluptuous, with the biggest pair of tits she'd ever seen. She had long pink hair, and a nurse's uniform. She watched as Senpai stole some glances at her. And then, how she walked straight into him.

"Ohhh my! Oh, I'm so sorry, dear, are you okay? Oh, I'm such a klutz..." The nurse said.

"U-uh..." Senpai stuttered.

"Oh, no, are you hurt?! What have I done! I'm training as a nurse and Ive injured someone on the first day! Stupid, stupid Muja, stupid!"

"O-oh, no, you're not stupid. It's a simple mistake, ma'am. I-I-"

"Are you sure? Oh, dear... i think I'd better examine you. Where's the infirmary?"

Senpai blushed at her suggestion.

"Oh, dear, you've gone all red... now I've given you a fever. We'd better go."

The nurse stood up, awkwardly, as she did so Senpai's eyes travelled down to her cleavage and seemed to be glued there.

She offered him a hand, helping him up. Ayano realised quickly she had no idea the effect she had on Senpai (and a few other passing students).

Here's the thing, most attractive girls she knew were fully aware of the effect they had on men. Hina knew that if she simply batted her eyes and smiled, there'd be a queue of men waiting to help her. This nurse seemed have no idea what she was doing.

Speaking of, Hina arrived by her side just then. "Oh my god. Look at the titties on that nurse."

"Mmhmm."

Hina stared at the nurse walking into the school with Senpai. "I think I might have a headache, you know."

Budo arrived next to her. "You have a headache?"

"You'd have a headache too if you saw the new nurse."

"We have a new nurse?" Budo asked.

"I think so. And she has the biggest boobs I've ever seen."

"Bigger than yours?"

"Yep." Hina said. "She's really fucking hot."

"I gotta see this." Budo said, taking Hina's hand. "Let's get a good look at this woman."

"Great to see you so enthusiastic, babe." Hina said as she was dragged off.

Ayano sighed. She could practically see Senpai developing a crush. And she knew this nurse likely wasn't interested in Senpai - she seemed a little too dense - but she didn't want her Senpai into any woman other than her. After all, this was the first time she had seen him have some kind of real crush since Osana.

She wandered past the infirmary, and heard her talking absentmindedly to Senpai.

"Oh, god, yeah. All my wisdom teeth are coming in. I can feel them all coming in my mouth."

She heard Senpai cough at the unintentional innuendo, and he laughed.

"Sorry, sorry."

"Did I say something?" the nurse asked.

"No, no. Don't worry about it."

Ayano's thoughts returned to Oka in her basement. She had done some pretty heavy stuff to her over the weekend; her rage had gotten the better of her. Oka was becoming increasingly broken.

And she knew what to do.
