Chiaki Nanami

Chiaki Nanami is one of the main characters in Danganronpa 2: Goodbye Despair, and notable for being a contributor to Jet Set Radio, and Chiaki Sakura Rose's namesake.

Biography
Chiaki Nanami died twice. Once as a real girl, killed by Junko Enoshima in Hope's Peak Academy, and once as an AI after a scheme by Nagito Komaeda failed. The AI created by Future Foundation failed, and Chiaki was gone.

King for a Crazy Day Tournament
The remains of her AI were used in the King for a Crazy Day Tournament as Contestant #2. She was apparently given the invitation by Nagito and Hajime, although this was a mere illusion created by Hades. Her source list included all Spike Chunsoft games, and classic arcade games, including Tetris. After losing to The Ultimate Fighters in Round 1, Chiaki began to glitch during interviews. She defeated Dan Reynolds, Metal Head, Illusiongale, and Failboat before losing to tournament champion Fawful in Loser's Bracket Round 5, netting her 7th place.

Post King for a Crazy Day
Chiaki Nanami was somehow recreated with a natural body by Byleth, with half of Byleth's soul given to her. Chiaki was later shown as a part of the Jet Set Radio group alongside King Dedede, Weiss Schnee, DJ Professor K, and Byleth, but she was forced to be hidden, and if she had to leave, she always had to be watched by someone, usually Weiss.

Chiaki was later shown in a rather depressing state, with Byleth's soul partially destroyed and the only part of it left inside of her. Hypercam and Hyperchan went over to comfort her. Chiaki wanted to fight and defend those that she loved, while everyone else wanted her to remain safe. Hypercam then told Chiaki that perhaps there was a way they could get her battle-ready to fight Junko.

They did help in the end, and Chiaki was given a blaster arm that she used to distact Junko later on.

Pre-E3, Chiaki was seen expressing her concern over the current state of things while also being sleepier than usual.

Personality
Chiaki has been shown to be a quiet girl, who's very shy and nervous around others. She's usually playing a game or falling asleep, and can be a bit awkward with weird habits she exhibits. She's very calm and is always willing to help others, even if they may be bad people.

Chiaki has always been shown to want to protect everyone, always trying to find a more peaceful solution. This is why she's not seen during DEATH BATTLE filming, while she knows it's all just for entertainment and the loser is (for the most part) revived, Chiaki doesn't like watching it due to the battling.

Chiaki doesn't usually talk to others unless it's about a game she's playing or is interested in. The subject usually gets her interested in a conversation. When you're friends with Chiaki, you'll find she's happy to help with whatever, even if she may end up a bit sleepy.

The only people Chiaki has been consistently talking to are the current members of Jet Set Radio, notably Weiss, who is like a motherly figure to her. She doesn't usually talk to Dedede however, most likely due to her first round loss in King for a Crazy Day. Dedede is confused by this, usually referring to it as "just a jest", although Weiss often tells him to stop pushing it.

Chiaki is very passionate when it comes to what she cares about, whether it be games or other people. She often finds a way to convince people to get what she wants, simply by following the "cute innocent girl" trope.
