Chisame has green eyes and steel blue hair, short in front and tied into a ponytail resembling a shark fin. She wears a shark tooth necklace, a blue shirt over a yellow top, and short white shorts.
Chisame seems a bit abrasive and rude, but she cares about Miyuki. She is very obsessed with sharks.
Chisame's father was a police officer who worked alongside Miyuki's father Mamoru Akasaka. When Akasaka went missing investigating Hinamizawa in 1993, Chisame's father investigated him and was killed horribly. Chisame went to the police station wanting to learn what happened, and found that it had to do with a "black card". Miyuki later found a similar card hidden away in Chisame's father's study, with a note saying it was found in Hinamizawa in 1978.
When Miyuki goes to Hinamizawa, Chisame covers for her while she's gone.
Role in the Story
Chisame is first mentioned in the first Chapter 2 TIP, where Miyuki calls her from a phone booth on her way to Hinamizawa. Miyuki asks Chisame to cover for her if anyone asks where she went, wanting to find out what happened to Chisame's father and what he knew.
The third TIP in Chapter 7 shows Miyuki and Chisame talking about the circumstances surrounding their fathers and.their connection to the cards. Chisame is unwilling to go to Hinamizawa but promises to cover for Miyuki while she's gone, saying she can only manage three days.
In Chapter 9, Miyuki and Nao return from 1983 but end up in an alternate 1993 world where the dam project was successful and Hinamizawa has been replaced by a lake. Chisame and Miyuki's mother Yukie arrive to pick up the two girls since Miyuki never came home after three days.
As the group heads home, they stop at a rest area where Chisame and Nao talk and start building a friendship. Later, Chisame has a private talk with Miyuki at a coffee shop and wants to know what she's been doing all this time. Miyuki explains to her about Role Cards and tsukuyami, aware that this Chisame is not really the one from her original world. Chisame decides to believe in everything Miyuki says to prove she isn't being manipulated by tsukuyami. Chisame and Miyuki give names to the various worlds.
Chisame comments on Miyuki's disposition and worries that she might succumb to the sleeping sickness. Miyuki is confused since no such thing existed in her world. Their conversation is interrupted when Chisame's pager blows up with a message from Nao, who returned home to find her mother unconscious. They go to a hospital near Nao's house and ask if Ms. Houtani was brought there, however the receptionist says they can't answer that. Miyuki and Chisame decide to sneak around the hospital to find Nao and end up in the ICU, where Nao is crying. Upon learning that the doctors took some blood from Nao, Chisame gets nervous when several staff equipped in hazmat suits appear and chase them.
The group is captured by the hazmat group, who say they could all potentially be infected. Locked inside a room together, Chisame explains that the sleeping sickness is a disease that causes people to suddenly fall into a coma, and currently there is no cure. Inside the quarantine room, they discover that Miyuki's school is on lockdown through a newspaper.
The group is soon able to leave when Natsumi Toudou provides them with a vaccine, even though they were actually used to test it. Miyuki, Nao, and Chisame then go to a police museum to meet Tomoe Minai, and prepare to go with her to New Hinamizawa to find the sacred tree there. Miyuki briefly goes with Tomoe to St. Lucia to investigate something there.
At New Hinamizawa, the gruop enters the ritual storehouse at the shrine there and find a box full of black Fragments. When they're suddenly attacked by tsukuyami, Chisame helps fight them using a harpoon Role Card. Tomoe reveals that she was familiar with Chisame's father and was looking into his murder. At the sacred tree, they meet Tamura, who asks them to give her the black Fragments so she can purify them and send someone back to 1983 with their power. Nao is the one sent back.
Tomoe informs Miyuki and Chisame of what happened in Hinamizawa in 1983 while driving back. They also learn a cure for the Sleeping Sickness is being developed by Takano Pharmaceuticals, owned by Miyoko Takano, and go to meet her. Takano says they have made a cure treating the sickness, but it's not been approved yet and is a secret. Shinsuke Kitajima then arrives and hands Takano a report rejecting the cure, saying it's still not safe.
Just then, they notice that a building nearby producing Sleeping Sickness medication has been set on fire and is being attacked by tsukuyami. Miyuki and Chisame rush out to engage them and run into Kawata, who urges the girls to escape while also claiming the world is better off without the medicine.
Tamura makes Miyuki see a vision of her, Chisame and many other people succumbing to the Sleeping Sickness and dying, and tells her that Une is responsible for it all. Miyuki wakes up the day after the Takano Pharmaceutical explosion and informs Chisame of what they need to do, and gets her continued help.
