Yumeko Mercury

**Yumeko Mercury**, is a participant of Sink or Swim's 22nd season, and a part of the killing game featured in *Danganronpa: Sink or Swim*. Her title is the **Ultimate Oneirologist**. Her reasons for appearing on the 22nd season appear to be to answer questions she has about the game itself. What those questions are have yet to be revealed.

## Public History

### Prior to Sink or Swim

Yumeko Mercury was born on May the 4th, XXXX in Rome, Italy. A young woman with a promising career in oneirology, Yumeko is known for furthering the study of sleep and dreams, detailing new information about lucid dreaming, as well as furthering research on REM and SWS sleep. In her career, Yumeko has debunked many popular myths about dreams. Aside from her influence on oneirology, not much else could be found about Yumeko’s life.

## Killing Game Life

### Introductions in the Theatre

Yumeko presented herself as a sleepy individual, sleeping through the prior introductions. She's shown to be a woman of few words, only introducing her name and talent before falling right back asleep. It could be assumed she's often got her head in the clouds, constantly daydreaming. When she's brought to reality, however, she's a stoic individual, proven to be unnaturally calm.

### False Alarm

When Octavius called the cast to the ship announcing it was sinking, Yumeko didn't have any particular reaction, keeping her composure. When it was revealed to be a false alarm to teach them how to react appropriately in such a situation, it seemed Yumeko didn't really care.

### First Motive

Upon hearing the first motive, Yumeko would only say a few words. Her expression, or lack thereof, remained stoic. It could be assumed that she found this motive uninteresting.

### Second Motive

Yumeko's secret during the second motive would not be revealed. Upon seeing the others, Yumeko reacted quite coldly, with her not comforting or showing any sympathy towards her fellow contestants.

### Third Motive

Yumeko would be handcuffed to Taiyou Shugosha. The two wouldn't interact much, due to Yumeko sleeping more often than not.

### Fourth Motive

Yumeko would have the collar around her neck. The collar would activate once in her stateroom, Yumeko quietly crying and attempting to sleep through it, though her attempts would be for naught.

## Name

Yumeko's name comes from *'Yume'*, translating to 'Dream' and *'Ko'*, translating to 'Child' in Japanese.

'Mercury' comes from the Roman god Mercury, known for travelling between both gods and mortals, two separate worlds. Yumeko would travel into two separate worlds herself, those being reality and fantasy.

## Physical Appearance

Yumeko has an hourglass body type, however her stature is quite short, standing at 5 feet and 1 inch. Her skin is lighter than porcelain, due to albinism. Freckles splatter all over her face and body, her very long hair is a very, very light blonde, so much so it can be confused for white. There are black areas in the hair and at the tips of her side strands, it’s a light grey. She wears a white dress shirt with a black collar, red string with an emblem tied under the collar as well. There are small white buttons on the end of the sleeves. She wears a fitted black leather skirt, along with a yellow oversized lab coat. The sleeves are tied to her waist, in a big bow. For footwear she wears black leather zip-up boots. The zip is a golden colour, the zippers have a diamond charm dangling as well.

## Personality

Stoic and cold, Yumeko is not an easy friend to make. She has a sharp tongue on her, ready to hurl an insult, but only if she deems it necessary. Always sleepy and has a habit of sleeping anywhere, regardless of how unconventional it is. She also has a tendency to let her almost child-like curiosity get the better of her. Thick skinned, rarely are one's insults important to her. She has little empathy for anyone and very often uses her head over her heart. Yumeko tends to enjoy playing her game of watching and analysing people based only on their looks and body language.

## Talent

Whenever the topic of dreams or oneirology is brought up, it seems that Yumeko is significantly more talkative than she normally is. Though she doesn't express her passion physically, one could sense the genuine love she has for her study. Yumeko has been able to analyse and interpret what dreams could mean, to a very accurate degree. She has also helped further research behind REM and SWS sleep and has formulated many plausible theories on dreaming and sleeping as a whole, using herself as a test subject and recording all of her findings in her dream journal. She is also considered an oneironaut, someone who explores their own dreams. She has explored the limits of dreaming, exploring and debunking myths of it as well. Because of this her talents were recognised, though she thinks that ‘talent’ discredited her hard work.
