Ultra Violet is another Yume Nikki fan-game produced by gozo-ropp.

It revolves around a young girl known as Sometsuki who explores her dreams while sleeping; she also appears to be a sleep-walker according to the writing "Sleep-Walker" (夢遊病) next to her name. Like many other protagonists, attempting to leave her room just results of a quick shake of the head and some sounds.

Ultra Violet strays on the lighter side of the spectrum - one of the primary visual motifs being rabbits, for example -- with the exception of a handful of violent or suspenseful areas.


Ultra Violet follows the traditional style of the genre, consisting of exploration and effect-hunting, vending machines (and buyable effects/features), but in addition plays up the collectibility of selectable menu skins, an aspect only briefly touched upon by other games.


  1. Violet - Default menu.
  2. Silver - Another starting menu on the computer.
  3. Monochrome - Another starting menu from the computer.
  4. Orange - A checkered orange menu with white font.
  5. Cookie - A pattern composed of cookies on a violet background.
  6. Hexe - (Hexe means "witch" in German) An arabesque menu in tan.
  7. Hexe Violett - An arabesque menu in lavender.
  8. Old black - A black base menu with white font. The menu which is used in Famicom world.
  9. Old blue - A blue base menu with white font.
  10. Violet II - A checkered violet menu, another starting menu on the computer.
  11. Green - A checkered green menu with white font.

The protagonist saves via the computer with a movable cursor, similar to those in The Looking Glass and Me. Additionally, from here the player can select from various menus and play a mini-game. Like Yume Nikki, in the dream world, sitting on Sometsuki's rolling chair and pressing the interact key while sitting facing the computer will allow you to move about in her chair. The chair reduce your speed to half instead of quarter in Yume Nikki, but you are unable to use effects until you leave from the chair in front of desk.


Not much is know about why Sometsuki refuses to go outside, or much about her dreams, but they are rather light, (except for a few worlds and some events) so it is possible there is something she wants to escape from, or doesn't want to face (similar to Lcd Dem's plot). However, as of version 0.04, no endings have been implemented yet, and a lot more events will most likely be in later versions of the game.


Name Image Description
Rabbit (うさぎ)
Sometsuki grows white rabbit ears and a tail. Pressing SHIFT turns Sometsuki into a small albino rabbit that increases her speed. When in Famicom World, the rabbit has violet eyes instead of red ones. Most NPCs will follow you around or get excited when this effect is equipped.
Headless (くびなし)
Sometsuki's head is missing. Pressing SHIFT toggles the bloody neck or no neck. While you will fail to wake up (pinch something) in the no neck form, trying to wake up in the bloody form makes Sometsuki pinch the remains of her neck instead of her cheeks.
Magician (まほうつかい)
Sometsuki wears a witch's robe and her hair becomes two braids. Pressing SHIFT lets her ride her broomstick which increases her speed. Also used for the witch flight event.
Lampost (ほうでんとう)
Sometsuki's head becomes a lampost head. Pressing SHIFT switches the light on to a soft green-blue (lavender in Famicom World), and other lamposts that are off will switch on. 
Nail Hammer (ネイルハンマー)
Sometsuki carries a hammer which servers as her weapon. Unlike most games, in order to actually use the weapon you will need to press SHIFT so Sometsuki switches to her "attack" pose. Most NPC's will try to avoid you when this effect is in attack pose.
Cake (ケーキ)
Sometsuki becomes a walking slice of strawberry shortcake. Pressing SHIFT causes her to put the cake on the ground, hiding her feet. She cannot move till you press SHIFT again. Certain NPCs will follow you around when this effect is equipped.
Coat and Muffler (コートとマフラー)
Sometsuki bundles up in a brown winter coat, a striped scarf and gloves. Certain NPCs will follow you around when this effect is equipped.
Egg (たまご)
Sometsuki becomes a walking egg, with only her face peeking though a cracked face in the middle. Pressing SHIFT closes up the egg, and warps you back to the nexus.
Android (アンドロイド)
Sometsuki becomes an android. Certain NPCs will follow you around when this effect is equipped.
Short Hair (ショートヘアー)
Sometsuki's hair is cut short.

Shikkenken (しっけんけん)

Ribbons/Pigtails (リボン)
Gives Sometsuki cute pigtails tied with ribbons. Certain NPCs will follow you around when this effect is equipped.
The style of this effect has been changed since version 0.03, and now you are able set the style you prefer (low pigtails or high pigtails) through Sometsuki's PC.
Sea Hare (アメフラシ)

Technical DifficultiesEdit

There is a known issue where downloading the game under the English locale will cause all of the files to be improperly named, resulting in the game being completely unplayable. To mitigate this issue, potential players must first set their locale to Japanese (not through AppLocale, but through the Windows Control Panel) and then download and run the game.
