Characters Edit

Yonaka Kurai Edit

The main protagonist of the game. Yonaka is a sophomore. She has dark hair braided in twin tails that reach her shoulder blades and wears a traditional Japanese school uniform. Yonaka wears a black blazer over her white dress shirt and a red bow around her neck, also wearing a pleated, red, plaid skirt that's typically short enough to see her undies whenever possible. She is innocent, kind, and calm, however, she seems to suffer from the same ailment as her brother; becoming insanely strong and crazed. It is noted that she has a strong gripe when she shakes hands. Yonaka deeply cares and loves her older brother, to a point where she changed her hairstyle to match her brother's. It's also shown that she found Nega-Mogeko cute, often blushing when she found him adorable and may harbour romantic feeling towards Nega-Mogeko, in one of the bad endings she ran away with Nega-Mogeko, ending with a romantic anime/movie cliche.

Shinya Kurai Edit

Yonaka's older brother. Not much is known about him other than having ran away from home once and that he likes his little sister, Yonaka. He seems to suffer from Dissociative Identity Disorder; quick to switch from his calm, kind and calculating demeanor to a powerfully violent psychopath. He is strong enough to kill without aid of a weapon, and it is suggested that the deed of slaughtering his own parents was done bare handed, as he left them in a puddle of blood. Shinya's eyes turn crimson and glow bright enough to be seen in the dark. Some theorize it could symbolize the mad change in his psychological state. Shinya's raven-hair covers the left side of his face, obscuring his left eye and has an ahoge (cowlick). He wears a gakūran (Japanese high school uniform) with golden buttons, implying he is still in high school.

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 extremely powerful; some having the strength to bring down the whole castle into rubble if they wanted to do so. They continuously try to sexually assault poor Yonaka.

King mogeko Edit

The founder of Mogeko Castle and its residents, including the Special Seven Mogekos. He is considered the 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. She has a special ability, "Magic Shield", which is a psychic barrier strong enough to take a rocket blast without issue.

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.
  • 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 VII. 
  • 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.

Cameo Characters Edit

Characters that are not related to the main story plot do still appear in the game.

Kurotsuno: Searching for her cell phone.

Hanten: Close friends with Kurotsuno.

Met: Searching for Kurotsuno along with Hanten.

Sullivan: Although he does not actually appear in-game, a letter addressed to Kurotsuno can be found. A tragic letter from father to daughter. **Definitely will be updating this later so that it'll be less confusing to those of you who are unfamiliar with Deep-Sea Prisoner's characters.**

Gameplay/Summary (CONTAINS 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 a handful of 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 (and 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).

You can save while being chased. 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.

Endings: Edit

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 Mogekos are raping Yonaka. It is unknown what happens after.

Bad End I "Assimilation" Edit

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

Bad End II "Insects" Edit

Mogeko larvae swarms into Yonaka's body, finding in her an appropriate "environment" to grow and hatch new eggs.

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 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 unwillingly swallows him. The insect will then infect her, revealing itself to be a parasite, and changes her into a fluffy Mogeko, the same as the others.

Bad End? VI "Elopement" Edit

Instead of choosing to face the King Mogeko, Yonaka admits her feelings towards Defect Mogeko and they choose to run away in order to be with each other.

Bad End VII "Fictitious Truth" Edit

Yonaka returns to her brother Shinya, only to be caught and murdered by him.

Normal End "Yonaka Castle" Edit

Yonaka kills her brother, returns to Mogeko Castle, and snaps. After a deity is awakened, Lord Prosciutto bathes Mogeko Castle in divine light. King mogeko is no more, and the new ruler of Yonaka Castle prevails.

Happy End Edit

Yonaka escapes the house and therefore her impending murder. She returns to the bus reminiscing what had just happened with her brother. Yonaka here realizes she can no longer "run away." However, before she could take action, the driver of the bus, a Mogeko, drives back to the castle and leaves her there. Yonaka quickly traverses the castle and is then teleported back to her house where she kills her brother. Just before dying, Shinya's real side is reawakened, reuniting the two for the final time.
