Description
Karyuudo Tsukishima is a character known as the tenth owner of a Future Diary. He is a middle-aged man who runs a dog kennel called the Tsukishima Kennel and is widely recognized for his extreme love of dogs, which borders on an obsession. He is the estranged father of Hinata Hino, a classmate of the main protagonist Yukiteru Amano. Tsukishima lives apart from his daughter and his wife, from whom he is divorced, largely as a direct consequence of his overwhelming devotion to his canine companions.
In terms of personality, Tsukishima is depicted as a wealthy gentleman who treats his dogs like beloved family members, preparing for them elaborate and expensive meals, including fine steak and thirty-year-old wine, while he himself is content eating simple and cheap fare like instant noodles. He holds a notably misanthropic worldview, believing humans to be inferior to dogs, and this detached attitude has led him to isolate himself from his own family. Despite his cold and manipulative exterior, there are hints of remorse regarding his failure as a parent. His speech is often grandiloquent, but he occasionally slips into a Kansai dialect, particularly when speaking with his daughter.
Tsukishima's primary motivation within the survival game is self-preservation, though he manipulates his daughter by promising that if he becomes God, he will turn back time to rebuild their broken family and make up for years of neglect. However, his true intentions are ambiguous, and he later admits this promise was a lie, using Hinata's desperate desire for his approval to further his own goals.
His role in the story is primarily that of an antagonist who operates from the shadows. After noticing the suspicious Aru Akise lurking near his property and mistaking him for a fellow diary owner, Tsukishima devises a plan to have Hinata eliminate him. He arranges to lend his diary to her, knowing her need for his love will compel her to obey. He uses a pack of trained, murderous attack dogs to stage a series of brutal serial killings designed to trap Yukiteru and his friends. Ultimately, his plan fails due to the intervention of Aru Akise and Yuno Gasai. After his scheme unravels, he is tracked down and shot in the back of the head by Keigo Kurusu, the fourth diary owner, who then frames Yukiteru and Yuno for the murder.
Key relationships define much of his character arc. His relationship with Hinata is central to his actions; he exploits her emotional vulnerability without hesitation, even as he acknowledges her suffering. His bond with his dogs is paramount, acting as both his greatest strength and the source of his detachment from humanity. He communicates with them via a complex system of codenames, referring to packs as Alpha 1, Alpha 2, and Alpha 3. He also has a brief but significant antagonistic relationship with Keigo Kurusu, whom he identifies as one of the supposedly nice people who are actually deceptive, moments before Kurusu kills him.
Tsukishima shows a small degree of development in his final moments. As he dies clutching a family photograph, he expresses a flicker of paternal concern, advising Hinata not to become a bad person like he did, suggesting he is aware of his own moral failings. A more pronounced change occurs in the third parallel world. Due to alterations in the timeline, Hinata is shown to have developed a genuine attachment to the dogs, visiting them regularly. This leads to a repaired and better relationship between father and daughter, and in the final episode, Tsukishima is seen walking happily with Hinata and a woman implied to be his wife, living a more peaceful family life.
Tsukishima possesses notable abilities stemming from his Future Diary, known as the Breeder Diary. This diary is unique as it does not predict his own future, but rather the future commands he will give to his hunting dogs and the subsequent reports from the dogs, such as their howls upon finding a target. He uses a large computer mainframe to coordinate his attacks and communicates with his dogs via radio devices and metal mouthpieces that enhance their bites. The diary allows him to organize his dogs into units and control them with precision. However, a significant weakness is that the more dogs he commands, the more difficult it becomes to track all their movements, leaving him vulnerable to attack while he concentrates on controlling the pack. His name is derived from Diana, the Roman goddess of the moon and hunting, reflecting his role as a hunter who uses animals to track his prey.
