He is shown to have dual nature, one being calm minded and always thinking, other being extremely violent and powerful, he is strong enough to slaughter his own parents without any weapon, leaving them into a puddle of blood, it's suggested he may have killed them bare handed since he did not possess any weapon. His eyes turn red as a symbol of madness or power awakening within him. His hair is a dark shade of black with and has an ahoge (cowlick).

Mogeko Edit

Non-existent creatures in reality who reside in Mogeko Castle. They love prosciutto and high school girls, they are perverted by nature and are shown to be really powerful, some having the strength to bring down a whole castle into rubbles if they need to. They continuously try to sexually assault Yonaka.

King Mogeko Edit

The founder of Mogeko Castle and its residents, including the Special Seven Mogekos. He is considered strongest Mogeko in Mogeko Castle, and his whole face becomes featureless with only one huge eye visible on his face when he gets serious and uses his dark powers. He has stated that he wants to "XXX Yonaka-tan."

Moge-Ko Edit

A seemingly cute girl with a twisted personality. She was created by the Mogekos. Candy, tabasco, and everything neat: those were the ingredients to create the perfect little girl. But they added concrete instead of candy, and a psychopath was born. Moge-ko frequently tortures and crucifies people that she dislikes, her special ability "Magic Shield" which is a psychic barrier strong enough to take a RPG without any problem.

Yonaka's friend Ylona-James

Seven Special Mogekos Edit

There are Seven Special Mogekos in Mogeko Castle. Each one serves as a guardian to each floor in the castle. With their guidance, Yonaka is able to escape from the Mogeko Kingdom and returns to her own world.

  • Somewhat Strange Mogeko - Guardian of Floor I. Gives Yonaka a special knife that can kill Mogekos with one blow, though the chance to do so does not come up very often.
  • Prosciutto Fairy - Guardian of Floor II. Gives Yonaka a key that will help later on in the game. Fabulous.
  • Blood Spirit - Guardian of Floor III. Warps Yonaka and Defect Mogeko to the next floor. Shy around women. 
  • Hasu - Guardian of Floor IV. Informs Yonaka of a secret passage to Floor V. Faithful to the Lord Prosciutto.
  • Mofurru - Guardian of Floor V. Leads Yonaka to the next floor through a heavenly beam of light.
  • Mogecuckoo - Guardian of Floor VI. Prevented mogekos from destroying the library. Warps Yonaka/Defect Mogeko to Floor VI. 
  • Nega-Mogeko - Guardian of Floor VII. Captured and held in a cell for execution, for having become a Defect. Decided to help Yonaka reach the top floor when they met in the prison on Floor III.

Gameplay/Summary (MAY CONTAIN SPOILERS) Edit

Floor I: "Welcome to Mogeko Castle!"

Yonaka meets Somewhat Strange Mogeko, who tells her how to escape from the castle. She must head for the top floor in order to return home.

Floor II: "Bread? RIce? Prosciutto!"

After a brief chase scene, Yonaka finds the Prosciutto Fairy and more light is shed on her current situation... well, just a little bit.

Floor III: "Here Comes Defect Mogeko!"

Yonaka is captured and put in a cell after discovering a book called "Defect Hunting."

She meets Defect Mogeko and he decides to help Yonaka flee from the castle. Blood Spirit warns them of the dangers awaiting on the next floor.

Floor IV: "The Dictatorship of Moge-ko"

Defect Mogeko and Yonaka run into Moge-ko and another chase scene plays.

Looking for another exit, the two discover Hasu and learn of a secret passage to the fifth floor.

Floor V: "The Very Hungry Grotesque Mogeko"

Yonaka and Defect Mogeko visit the hospital and obtain some weapons. Defect Mogeko teaches Yonaka about the genesis of Mogeko Castle.

Floor VI: "The Nightmare Never Ended"

There are X chase scenes in the game, and also a door maze. In the final chase scene, the game may crash due to there being too many events on the map (all those Mogekos chasing you). To get past this, you may try saving as you go along or you can download a save file from vgperson's website that allows you to skip the ordeal (English version only).

Oh, look. A note within a note. You can save while being chased, yes. Actually, you can save at any point (excluding cutscenes, etc.) in the game. However, if the game crashes while you are doing this, then the file cannot be loaded.... which is pretty risky if you're not careful about when and where you save.

If you're going to do this, it is recommended that you take note of where the game crashes after progressing from your last save, saving the game somewhere before that point. Saving when you've passed some of the Mogekos will hopefully cause less of them to be on the map after reloading your save file.


...Well, unless you've played or watched the game already. Anyways! There are X endings in Mogeko Castle. They are listed here in chronological order.

Bad End 0 "Everlasting Dream" Edit

Yonaka hesitates to enter the castle and is found by the Mogekos who were chasing her in the forest. They are able to catch up with her and in the next scene, Yonoka's muffled screams are heard along thrusts; suggesting that the Mogeko's are raping Yonaka, it is unknown what happens after.

Bad End I "Assimilation" Edit

Yonaka, upon unleashing the madness of a certain Mogeko in Floor ?, becomes one with the darkness of Mogeko Castle.

Bad End II "Insects" Edit

Mokego's larvae swarms into Yonaka's body, finding in her an appropriate "environment" to grow and hatch new eggs. Of course, Yonaka will die because of that.

Bad End III "Meat Party" Edit

Pressing a button to open a large cell, Yonaka is eaten by the mad Mogekos within.

Bad End IV "Toy" Edit

Disregarding Hasu's warning allows Yonaka-tan to be found by Moge-ko. Instead of being crucified, Yonaka becomes Moge-ko's 'toy' and is tortured from that point onward, presumably until she dies.

Bad End V "Parasite" Edit

Touching a cat-like insect, Yonaka will be attacked by that, unwilligly swallowing him. The insect will then infect her, revealing to be a parasite, and changing her into a fluffy Mogeko, the same as the others. Probably dying a month after.
