Howdy, and welcome to my Mogeko Castle story.

To explain, this is based on the somewhat popular "adaptation," "Mogeko Castle With Voices." It's going to be a sort of AU where Yonaka kills all Mogekos possible to kill in the game, in order to portray her slow descent into insanity (as seen in the Normal Ending). So, let's begin this twisted ride. Also, see if you can catch all the references!

Floor I: Somewhat Strange Mogeko

It was supposed to be a happy day. Brother was finally coming home. Yonaka Kurai had been so exited, so longing to see her dear Shinya.

But today was anything except happy.

First she gets off at an unfamiliar station, then she gets chased around by little yellow rapists, then she wanders into their castle and gets locked in... Today was not a good day. It seemed like she would find no relief from this nightmare.

Nightmare was definitely the most fitting word for this situation- it all felt so unreal, sometimes she'd pinch herself to see if that'd wake her up. No success. Seems there's no escape then.

Despite this, she couldn't help but marvel at the actually friendly Mogeko in front of her. "No need to fear me. I won't attack you. I much prefer... to just sit here and drink tea, you see." He called himself the "Somewhat Strange Mogeko"-an odd name, to be sure. Nevertheless, they carried on a polite conversation, and he was happy to share some advice to aid Yonaka's escape. "So to return via the door on the top floor... seems most reliable."

...Yet Yonaka couldn't trust him. He looked like one of them... what if this was a trick? "Do you distrust me? Perfectly reasonable, as I too am a Mogeko..."

!...Mind reading? Impossible.

"Ah, that's right. I'll give this to you." He handed the girl...a knife. "Hwhaaa?!" What is he doing? "Take it for self defense."
"W-what do I use this for?" "Is it not obvious? To stab Mogekos to death."

! Why is he handing this to a high school girl?

"While there are many, they aren't very sturdy...And that knife is special. It can kill Mogekos in a single blow."

She moaned again. "? ...What is it?" And again. "Why? Why are you being so friendly?"

His answer was...worrying. "Hahah. Yes... why indeed... Just on a whim." So he could suddenly attack her in a few seconds if he just got the urge?

She looked around a little more, and chatted with him a bit more. Among the things in his room were a diary containing records of... his masturbation and bowel movements. Yuck.

So she went to say her goodbye. And that's when she started feeling weird. Her head began to hurt. Then... something appeared in her mind. A memory...?

"Mogegegegege! Found you, Yonaka-tan! You won't get away this time..."

Oh, dear...

"Everlasting dream on our wedding night..."

She remembered the endless barrage of Mogekos, the searing pain as they all pounded her hard as they could...
Yet she woke up afterwards, in front of the castle, unharmed. Why, she wondered? Yet she pressed on.

...The thought that this being could do the same to her... no.

...She remembered when her body was engulfed in darkness. The Mad Mogekos inflicted a torture onto her unlike anything she had ever experienced. Worse than the regular ones, even. Yet again, she woke up, in that same spot, unscathed.

She felt herself spacing out a bit as she went to talk to the Mogeko.

"There's just...one more thing." "Yes?"

"...Thanks for the knife. It was nice of you to have me over. Take care."

"Godspeed, Yonaka, and good luck."

"And... thanks for letting me test out the knife."

"? ...Okay?"

"So... um...sorry. But I have to protect myself."

...She pulled out the knife. She aimed it at him.

"?! Wh-what are you doing?"

"...Protecting myself. Again, sorry."

And so she swung. And stabbed. Again and again, as the poor soul screamed in pain. Until he was nothing but guts.

She left the room, still in that...trance. Ready to make them pay.

"Hey guys, I just learned a new magic trick. Wanna see?"

"Oooh, let me see!" Said the unsuspecting victim.

"Time for you to... DISSAPEAR!"

...Their screams of agony were delicious, she had to admit. "Watch out Mogekos," she declared, "a new Yonaka is here; one that's not weak and defenseless anymore!"
