Ceroba Ketsukane

Ceroba is a fox-like monster with beige fur and long, wavy ginger hair. Her hair is tied up in a ponytail by a red ribbon with a small gold bell in the centre. She has a long, white kimono with red trimmings; a red obi sash tied around her waist and white boots.

Chujin Ketsukane- Late Husband Kanako Ketsukane- Late Daughter Starlo- Childhood Friend

Brilliant, supportive and skeptical, Ceroba is a powerful ally when it comes to wanting to help those closest to her. She is shown to care a lot for her loved ones. However, she is highly stubborn, even going so far as to question the true meaning of Asgore's words when confronted with the truth of her husband's employment. Because of this, she is firm on her husband's legacy as a scientist and a hero of the underground, and she spends the days after her husband's passing trying to complete the work that he had passed down to her. However, when she finally tests it on Kanako and has it result in her falling down, Ceroba's beliefs strengthen to the point that she is fully willing to kill Clover to save the rest of the underground.

Ceroba is observant, and can tell how others are feeling just by a glance, and can also notice a shift or change in the other's moods. Though she is not hesitant to say them to others, she will try to hide them from those she loves as long as it does not harm others. An example of this is her relationship with Starlo, and she didn't confront him about his behavior until after his friends had come up about how it was making the rest of them feel. She is quite honest and straight-forward as well. This is evident from how she treats Starlo's shenanigans in the Wild East, saying she doesn't understand it and acting nonchalant when included in them, as well as her realistic assessment of Clover's fate before and after her battle in the Pacifist route. The exception to her realism is her husband, Chujin, who she always holds in high regard no matter what information is displayed to her that may say otherwise.

Chujin was Ceroba’s husband. It is shown throughout the game, (mainly in the Pacifist Route,) that Ceroba loved him very dearly. In the Steamworks, it is clear that Ceroba shows somewhat strong resentment towards Asgore because of his disregard of the eventual creation of Axis, (Chujin’s creation). Despite this, Ceroba and Chujin were somewhat distant when it came to Chujin’s work. Until going into the Steamworks, Ceroba was unaware that Chujin had finished creating Axis. She also remarked that she does not see Chujin very often, as he is usually in his lab[citation needed]. Most of all, she was not aware that Chujin had been fired from this job, claiming that he had retired. Regardless, it is Ceroba’s strong love towards Chujin, possibly to the point of unhealthy obsession, that influences her motivations throughout the game, (specifically in the Pacifist Route.) She is willing to obtain Clover’s soul by ending their life, and deceive Starlo in order to progress his plans.

Kanako was Ceroba’s daughter. Ceroba is shown to deeply care about Kanako through dialogue and flashbacks. At some point, after Chujin's death, Kanako discovered the tapes in the basement. Upon finding out that Kanako discovered these tapes, Ceroba told her that she wasn't going to make Kanako a part of Chujin's plans. Despite this, Kanako eventually convinces Ceroba to use her soul, injecting the Integrity SOUL extract into her to extract the serum from. Kanako fell down soon after Ceroba gave her the extract which caused Ceroba to fall into depression. Ceroba's pragmatism, however, lets her get over Kanako's death, and she is willing to use what's left of her SOUL to continue with Chujin's plan.

It is shown throughout the game that Starlo and Ceroba are close friends. Presumably ever since childhood. Despite that, during the Pacifist route she still refuses to tell Starlo about her plans to finish Chujin's work using Clover's soul, and attacks him right before the final boss-battle of the Pacifist route. She does still deeply care about him though as shown during the Genocide route, when she snaps upon his demise at the hands of Clover. This is what initiates her Genocide route battle.

When talking to her in the Steamworks, Ceroba mentions that she considered dating Starlo when she was "a naive kid", suggesting their relationship was a lot closer in the past. She also states her reason for moving on was because she wanted to grow up, and Starlo didn't follow.
