All right, all right, I've got more for you. Put away the pitchforks.
Rather than going for a real rewrite (which I will contemplate when I am cold and dead), I opted to clip off the end and add more. Hopefully you'll all find this more palatable.
Take two!
Kurumu grit her teeth as she gripped her character sheet tightly. "Oh, really? You think I don't know my place? I'll show you exactly where 'my place' is!"
The succubus turned toward Yukari. "GM! Do I need to roll anything to change religions?"
Yukari blinked. "No."
"Good! Then my maid drops to her knees and prostrates herself before her new goddess, the management guru Evil Moka!" Kurumu said firmly and without a hint of shame.
"Kurumu! What the hell?" Ranma demanded.
"She killed wolves and she killed YOU. What am I gonna do, smack her with my broom? I'm getting in this cult thing early while I still have all my hit points," Kurumu said shamelessly. "Don't worry, I'll make sure Kouma gets your coffin."
"And what about MY funeral?" Ranma demanded.
"Well, I'm pretty sure cleaning up the corpses so that nobody can find them is going to be my first service to my new religion. It's going to be a long time until anyone knows you're dead."
"Evil Moka wants you to know that she is pleased, Kurumu, and that she forgives you for always flaunting all your extra charisma in front of her," Moka said in a deadpan voice.
"I thought our charisma scores were the same," Kurumu said, quirking an eyebrow.
"I wish," the vampiress mumbled as she stared down at her chest.
'Well, this is a surprise! What a lovely ending! I think I might like this game!' Evil Moka thought with a mental laugh.
"Moka, Shutarou returns to and bows, asking if it is time to for you to shed this mortal shell and ascend to paradise," Yukari said suddenly.
Inside Moka's head, the laughter slowly trailed off into a confused mumble.
"What's this about shedding shells?" Ranma asked.
"Well, she did say a SUICIDE death cult. What did you think was going to happen after she murdered everyone else?" the young witch asked.
'Huh. I forgot about that part. Well, let's get the brat to go first,' Evil Moka decided.
'You are the WORST babysitter,' Moka quipped in her head before she spoke. "Evil Moka wants Shutarou to go first. Rolling to convince him... it's a 13."
Yukari shook her head, much to Moka's surprise. "Shutarou looks quite doubtful as you make your case, and responds by saying, 'But my goddess, without your holy presence to guide me, how will I know the way?'"
'Precocious little runt, isn't he?'
'He stabbed three adults to death. I don't think "precocious" really covers it,' Moka thought wryly.
'Okay, let's hold on and think about this. He's still fanatically loyal to me, and I have high negotiation skills. Maybe if I try-'
Moka suddenly spoke, her eyes narrowing. "My manager, enraged that her pawn would dare defy her, attacks Shutarou."
'HEY! I did NOT do that!' Evil Moka complained.
'I'm sorry, what? I can't make out what you're saying, I think I'm getting bad reception,' Moka thought as she poked at the Rosario, a vein bulging on the side of her head.
Yukari nodded. "Right. Shutarou prepares to defend. Roll initiative."
"My maid hides in the broom closet," Kurumu said, "and listens carefully for the sound of combat to stop."
"You know, I really have to take this situation against the theory of the game," Tsukune said while Moka and Yukari continued rolling in their one-on-one combat, "a little kid killing four adults just doesn't happen in the human world. Not during a babysitting, at least!"
Ranma grunted. "Probably true. I've only seen these things happen in school."
"You've seen a kid around here who's that dangerous?" Kurumu asked.
"No, no, I was talking about my human school," Ranma corrected, waving his hand in front of him. "This one little girl was a real pain in the ass. Never killed anyone, but she would knock out entire classes at once some days."
"Ranma, I really wish you wouldn't undermine my idea of reality faster than this school does," Tsukune mumbled, massaging his temples.
"Then you should probably never bring up the elderly when I'm within earshot," Ranma noted, "the stories I have would BREAK you."
"Ah! Darn! It looks like my manager is at 0 HP!" Moka said with mock concern. "It seems she's been laid low by her own violent, short-sighted scheme! And there's no NURSE to help her, either!"
'See, now why do you have to be like that?' Evil Moka asked, 'I had ascended to being an object of worship, the most annoying man I've ever met had died painfully, and everybody was having a good time. And now it's ruined.'
'You got everyone except Kurumu killed! Nobody was having fun except you! And maybe Yukari. She keeps giggling when she thinks nobody's looking.'
'It was all to kill Ranma! You can't tell me that wasn't worth it!'
'It wasn't worth it!'
'You used to be cool.'
Yukari spoke up after she finally finished recording her notes. "And so Evil Moka, business manager, has fallen to a glorified quest item! Kurumu, make a stealth roll as he searches for new victims."
The succubus gulped as she rolled her die. "Is a 17 enough?"
"Okay. Shutarou pouts as he fails to find anyone else, and promptly gets bored of playing assassin. Also seeing that all the blood is starting to slick up the floor, he decides to leave the house. Kurumu, you hear a distant click as the front door opens and then the sound of it closing."
"Wait... playing assassin? He was just playing?" Tsukune said, gaping.
"Well, you didn't seriously think a level 2 manager could really control a level 16 character, did you?" Yukari scoffed. "He was just playing around."
Moka winced as her head was suddenly bombarded with angry profanities from within.
"He killed four people!" Tsukune protested, slamming his hands on the table.
"No wonder his parents were so keen to get rid of him for a weekend," Ranma said, "they didn't even come back after some stranger snatched him up and slammed the door in their faces."
"So... does this mean I win the game?" Kurumu asked cautiously.
Yukari scratched her head. "Well... In theory, no, but seeing how you're the only survivor of the household, it's hard to really to argue otherwise."
The succubus cheered, throwing her arms up into the air (and incidentally treating the boys to a lovely view of her bouncing cleavage). "Yes! I won!"
Ranma snorted as he got up to leave. "Spoony maid."
