Suzuka Shinoyama

Suzuka Shinoyama (四乃山涼火 Shinoyama Suzuka) is the deceased eldest granddaughter of Rozan Shinoyama and older sister to the twins Shizuki Shinoyama and Kazuki Shinoyama. Her spirit has followed the twins for the past year, born out of Suzuka's love for them and fear for their safety prior to her murder at Know's hands.

Suzuka's spirit is restored when the Corpse God successfully foils the imposter's murder attempt on the twins, with her memories, consciousness, and appearance while living all returning to her.

Appearance
At the time of her death, Suzuka was a young woman with light-colored shoulder-length hair and bangs, the longer of which she kept pushed back with a black headband. When her memories and consciousness are fully restored to her half-formed spirit, she regains her appearance as it was in life as well.

As a warped spirit, she has long white hair that covers her eyes and grames a large, keening mouth; meanwhile, her exposed arms and long, spindly hands, as well as what is visible of her face and neck, exhibit charring that may be a reflection of her murder. While the spirit appears to be wearing a dress, it is also seen cloaked in black smoke or mist which the dress merges with, attesting to her incorporeal form.

Personality
When alive, Suzuka loved her family and was especially close with her young sibling Shizuki and Kazuki. It was this love and sweet thoughtfulness on her part that led her to personally search for Kazuki's dropped purse, and was strong enough to cause her spirit to manifest after her murder. Her spirit itself has lost half of its consciousness, and is defined by the feelings that manifested it: it fears for the twins' lives, and follows them out of an overwhelming need to protect them. It seems to be aware that its ability to protect them as a spirit is liminited, and is often seen weeping for someone - anyone - to protect them.

According to the Corpse God, the spirit is not so far gone that something cannot trigger it to fully regain consciousness.

Chronology
Two years before the start of the story, at the Shinomiya Manor, Suzuka noticed Kazuki and Shizuki together, with Kazuki crying. The twins explain that they had been in the garden until Kazuki noticed she dropped her pouch. They wanted to go look for it, but it had become dark outside. Suzuka offers to look for it instead since she is their big sister.

Suzuka searches through the garden and eventually finds the pouch, however she notices some voices nearby. Peering through the bushes, she sees a relative having a discussion with another man, Know. The duo discuss a job to burn down the estate, and Know suggests to pin the blame on Kazuki and Shizuki. Hearing that, Suzuka becomes shocked, but Know also realizes someone is eavesdropping.

Suzuka runs away to warn her family, however quickly after she enters the boiler room it bursts into flames. She feels the room getting hot and is confused at the heat. The flames eventually overwhelms her and she dies screaming in the flames.

Despite dying her spirit remained. Not realizing she died, Suzuka finds Kazuki and Shizuki watching the burning of the boiler room, and is relieved that they are alright. She tells them to run away to the police, however, because she is a spirit they do not hear her. She tries to embrace them, but her arms just go through their bodies. Unable to do anything, she asks for somebody to save Shizuki and Kazuki over and over. Thus, she begins to possess the twins.

By the current time, Suzuka has lost half her consciousness and has a larger, monstrous form, but continues to watch over Shizuki and Kazuki. When the twins go to visit their uncle Polka who had not retuned home for ten days, the Corpse God notices Suzuka's possession of the twins and her request to have the twins saved. He tells her he understands and that he will protect the twins.

The next day when Corpse God visits the Shinomiya estate, Suzuka is seen over the twins as they welcome the Corpse God. After the family meal, Suzuka is seen again as the twins leave to go to their room. She says over and over the that something is coming: the fire.

In their room the twins discuss Polka as Suzuka silently looks over them. Then there is a sudden loud sound, and a servant rushes into the room. He tells the twins there has been a fire and they need to come with him at once. The twins follow after him, but Suzuka reaches out to the twins yelling “No!”

The servant leads the twins to an underground escape route, but Kazuki hesitates stating there is no escape route here. The servant states that there is one as he spent two years making it. He then prepares to attack the twins. Suzuka tries to interfere, but her arm just goes through his body. Just as he is about to land his attack on the twins, Misaki kicks him in the face and knocks him to the ground.

Miskai tells the twins to go upstairs and escape. However, when Kazuki and Shizuki try to go up they find their route blocked by flames. The twins crouch low to avoid breathing in the smoke. Shizuki wonders if this is their punishment for getting Suzuka killed and if she is mad at them. Kazuki tries to disagree, before agreeing with him. Rubbles collapses above them as they decide to apologize to their sister, accepting their impending deaths.

Corpse God arrives in time to shield the twins via necromancy. He ttells the twins that their sister is not mad and that she will always love them. Even though the twins cannot feel her, Suzuka embraces her younger siblings, her form having reverted to her original appearance.

After the fire incident has been resolved, the twins and Suzuka see off the Corpse God and Misaki. Misaki asks if the Corpse God will form a pact with Suzuka. The Corpse God says he will someday, but is fine for leaving it for now, as he watches the happy three siblings.
