Koichi Nozawa

Koichi Nozawa is a participant in the series Danganronpa: Sea Semester. His title is the Ultimate Aquarist in the aquarium.

## Personality

Koichi is a cheerful and childish boy with great interest in marine life. He seems to be unaware of things that aren't related to marine life or confectionery, which is seen when he didn't approve of Yugi eating veggie chips, thinking they were spoiled vegetables. He is often seen using phrases incorrectly, rather more proof of his unawareness. Despite all that, he is very smart in the ocean world, saying fish facts from time to time. A big part of his character is him speaking to rather unusual things, a fish he named "Blobby" in the aquarium floor and a close friend he calls "Nene" that he introduced to Yugi in a free time event.

## Danganronpa: Sea Semester

### Prologue: Rising Tides

Waking up in the aquarium, Koichi was immediately amazed by the fish tanks. He tapped on the fish tanks, talking to the fish while everyone else introduced, argued, etc. He was quick to name one of the fish in the tank, "Blobby". He was still in his own world when the killing game was introduced, but he tried to bribe Wales into letting them leave in exchange for a lot of food.

After Wales had showed the group around, Koichi went back to the aquarium floor to continue talking to the fish "Blobby". Questioned by Yugi about his ability to speak with fish, Koichi appeared to have a hard time comprehending Yugi's vocabulary. The two then went to the banquet to search for candy. Finding gummies in the cupboards, Koichi shared them with Yugi who he calls "Fire man". Koichi seemed to disapprove of Yugi eating veggie chips, then proceeds to not know the difference between various vegetables. Koichi then tells the group fish facts, then Yugi provides a fire fact and explains to Koichi what a fountain is, although Koichi zoned out as he explained the fountain due to the vocabulary being too difficult for him. Koichi then explained to Yugi how he isn't a real fish and questioned if Yugi was born in fire, to test it out he poked Yugi. When Yugi told him to use his head, Koichi tried poking him with his head, resulting in an embarrassed Yugi leaving the banquet.

When Wales called everyone to meet up in the aquarium floor to announce the motive, a chest filled with 1 billion coins, Koichi questioned if the coins were chocolate coins. When Koichi got told they weren't chocolate coins, he instantly shifted his attention from the motive to tapping on the fish tanks. He then scolded his friend "Blobby" after Yugi had told him "Blobby" snitched on him. Before Koichi could question what a hentai book that Hikari mentioned was, his ears were covered by Yugi. Afterwards, he went to sleep in his room.

### Chapter 1: Treasure Hunt

Having waited for the party, Koichi arrives at the banquet hall for the party rather excited. He mentions how he had a lot of sleep just to be energized for the party. Koichi agrees to Larry's statement about nothing bad will happen in the party, stating that nothing bad ever happens in parties because they party and eat cake. Koichi then showed the group the "cake" he made, said cake being a piece of bread with sprinkles on it. Koichi then excitedly watches Hikari light the cake on fire, waving at Yugi and calling the cake "spicy cake". When Yugi pulled Koichi away, he got confused and said that they have to eat the cake that's on fire. Yugi then threw water at the cake, much to Koichi's disappointment as he stated that this was supposed to be a cool surprise that he and Hikari planned out. When Brandon reassures the group that there's still the 16 layer cake that represents each person, Koichi got excited about having a cake based off himself and wanted to instantly try it. Koichi tells the party group that they will be playing "fish fish frog" which seems to be a knock-off version of duck duck goose.

After everyone had sat down in a circle, Brandon said he'll go to the bathroom to which Koichi said he'll tell Brandon what he missed of the game when he's back, however the game was cut short as the group heard Brandon's scream outside. Koichi got confused as he watched everyone leave in a hurry but finally left to the aquarium floor last not expecting to see the corpse of Lexi inside the fish tank, much to his horror of a corpse being in a place he once adored he stared in horror at the corpse. He noticed Hazel's odd behaviour but he was more focused on the death, hugging Temmie back as he cried until Captain Wales gave them the Aqua Autopsy. During the investigation Koichi picked up a shirt on the floor, he then realized who this shirt may belong to from the distorted logo. Koichi heavily refused to tell Temmie who he thinks the shirt belongs to even after a lot of attempts to get him to say it, stating that this probably isn't related to the person and doesn't want anyone to suspect them because of Koichi's words.

## Trivia

* Koichi tells Yugi that he was discussing a plan with his friend "Nene" and even introducing "Nene" to Yugi, heavily implying Koichi has imaginary friends.
* Koichi mentions another person to Yugi who he calls "Doctor Curiosity". While it may be another imaginary friend like "Nene" he also mentions that "Doctor Curiosity" is visible to everyone unlike "Nene".
	+ In a free time event, it was confirmed by Koichi that Doctor Curiosity is his father.
* Another name Koichi mentions is "Nori", though it's unknown who or what "Nori" is. Koichi said that he and "Nene" discussed a plan to defeat "Blobby" and save "Nori", so "Nori" could be another imaginary friend, a fish like "Blobby", or a real person.
* Koichi's outfit is just a swimsuit, he wears a crop top jacket and shorts on top of it.
* Multiple free time events imply Koichi has regressive behaviour from a traumatic brain injury.
