Shūji Fujigawa

Shuji Fujigawa (不死川 周二 Fujigawa Shūji) is a character featured in Danganronpa Gaiden: Killer Killer.

He is a childhood friend of Takumi Hijirihara and one of the two survivors of the Giboura Massacre which turned Takumi into the Killer Killer. After discovering this, he became passionate about helping his friend understand the horror of murdering and make him drop this Killer Killer persona.

He impaled Misaki Asano as the last resort method to make Takumi understand his philosophy.

Later, it was revealed that Shuji is the first and official bearer of the title Killer Killer (キラーキラー).

Appearance
Shuji is a young man who has silver hair and a prominent ahoge. He carries a mischievous face to match his wicked personality.

Personality
Similarly to Takumi Hijirihara, Shuji is very fond of cramped spaces—so much so that he does not even have a bed and prefers to sleep inside a locker.

He likes to presents himself as a calm and collected individual, but is far more sadistic than that.

Prior to the Tragedy
Shuji attended Giboura Middle School where he met and had a friendship with Takumi. They were both witnesses of the Giboura Massacre and the only survivors of it thanks to Shuji hiding himself and Takumi in a locker.

Chapter 4 - Sting Casino Murders
Shuji watched from the audience during the events of the Killing Festival, including Juzo Sakakura 'unmasking' Takumi as the elusive Killer Killer. He watched in silence as chaos broke out and likely left before he was apprehended by the Special Forces.

Chapter 6 - Possibility of Despair
Shuji returns to his bedroom and sits inside a locker that is replacing his bed. He comments how he is able to finally relax, and mulls over the reveal of Takumi being Killer Killer. Throughout this, he looks at a photograph of a Takumi and himself, taken when they were middle schoolers.

Chapter 7 - Pre-Wedding Mystery Tour
Shuji is found lying on the floor by Misaki Asano during her trip with Takumi, who quickly gets up and introduces himself as his long-time friend. He then reveals Takumi's true identity as the Killer Killer and requests Misaki's help to make him "quit the Killer Killer thing".

Chapter 8 - Beginning of Killer Killer
Shuji explains Misaki about his responsibility in Takumi becoming the Killer Killer and explains her what happened in the past. He explains the reason for Takumi's change being his fault is that while hidden in a locker, he could still watch the scenes through the gaps of it. He also reveals her the Giboura Massacre perpetrator's identity being Mukuro Ikusaba. Feeling too much guilt over these traumatizing events, he ends up vomiting.

Chapter 9 - Don't Kill
Shuji followed Takumi and Misaki to the Future Foundation's 8th Branch, ending up vomiting again as he saw the massacre of the entire security crew. He was the witness, along with Misaki, of Takumi dealing with and attempting to murder Mukuro Ikusaba. He attempted to stop him from killing her, grabbing his knife by the blade. However, his efforts were in vain.

After Takumi dealt with what was revealed to be Mukuro clones, Shuji used a last resort method and impaled Misaki through the chest with a dagger, asking Takumi about how far he had to go for him to understand.

Chapter 10 - Killer Killer Killer
After stabbing Misaki in the previous chapter, Shuji continues to beat her up relentlessly, pulling at her hair, in an attempt to convince Takumi that murder is wrong.

Whilst holding Misaki captive, he spills his backstory on how the Giboura Massacre had changed him for the worse. After exiting a locker, he found the class representative still alive, on the ground. The class rep looks at his perplexedly, asking Shuji why he didn't save him since he aspired to be a police officer. Repulsed by his face, Shuji kicks him repeatedly until he succumbs to death. Horrified by the murders he witnessed, he too becomes a Killer Killer, but rather to clean up the world.

One day, while trying to kill an unnamed serial killer, he spots Takumi, who offs him before he's able to. Shuji then vows to save Takumi from the murders that changed him so much.

Shuji then attempts to stab Misaki in the back, but is then stopped by Future Foundation employees Ruruka Ando, Sonosuke Izayoi, Juzo Sakakura, and Ikue Dogami. Shuji then sets off an explosive and retreats, leaving a shiny collar on Misaki's neck.

Chapter 11 - My Buddy is You
Shuji starts a broadcast in which he reveals that he has set several bombs around the country and the only way to defuse them is to kill Misaki.

Chapter 12 - To Each Their Own Murder Intent
In the end of the chapter, Shuji was waiting for Takumi and Misaki's arrival in the former Senbo-Ura Middle School (was also formerly named as Giboura Middle School), hiding inside the same locker when he hid with Takumi during the Giboura Massacre.

Takumi Hijirihara
Takumi is Shuji's childhood friend. They frequently hanged out with each other during middle school and even agreed to pose for a picture together. Shuji deeply cared for Takumi before he became Killer Killer, often protecting him from bloody scenes due to his fear of blood back then. It seems like Takumi forgot about Shuji since the incident, unable to recognize Shuji at all.

After the Giboura Massacre and discovering Takumi's Killer Killer persona, Shuji felt immense guilt over this change - blaming himself for being indirectly responsible about such a change. He later reveals that the event changed him as well, as he too became a Killer Killer, but did so in order to "clean" the world, not out of a love of passionate killings like Takumi. He has become since then passionate about bringing Takumi back to his senses, going far enough to stab Misaki Asano to make him understand.

In chapter 13, it is hinted that Shuji is in love with Takumi.
