Kō Inuzuka

Kō Inuzuka (犬塚 甲) is a character featured in Danganronpa Kirigiri.

Ko was alongside four other detectives from the Detective Library who went to the Sirius Observatory where he, unknowingly, took place in a Duel Noir. During his time at the Observatory, he was murdered by the culprit.

Appearance
Kō is a short and fat man who is usually drunk and carries around a bottle of liquor concealed in a bag.

Personality
Yui Samidare initially thinks Kō is a poor drunk man, judging from his looks. Her impression of him changes drastically after Kō deduces her lifestyle simply by taking a look at her. Despite his love for alcohol, Kō is a keen detective and takes on the role of a wise mentor figure towards the others. However, he also likes to show off his easily obtainable knowledge, indicating he loves trying to make himself seem impressive.

However, this love for the spotlight does reveal something darker when its revealed Ko would do anything to raise his rank in the Library, even if it means committing arson and killing others if it gives him a way to shoot up quickly. He also is implied to be somewhat perverted.

History
Kou is 41 years old, making him the oldest detective of the group, and specializes in murder. He also has the highest rank. His DSC number is 943. On December 22nd he was called out by Tadashi Asakura under the name of Yoshizono Ooe to meet up at the Sirius Observatory and met up with four other detectives at Hataski Station, being the fourth to arrive. There he met Yui Samidare and, while the girl was initially disapproving of his behavior, showed himself as a capable detective by figuring out her lifestyle just by observing her alone. From there, he joins the other detectives in entering a van that will take them to the Observatory. During the ride, he was insulted by Eigo Amino until he silenced him by revealing his DSC rank, which was higher than anyone else in the van. As a result, this caused Eigo to fawn over him and allowed him to explain his knowledge on astronomy and the Observatory (something that Yui points out was either out of date or could be looked up easily). When the van stopped in the middle of nowhere and they were forced to continue on, Ko managed to get Eigo from threatening the driver and to continue onward. When asked about on what he plans to do about heat, he mentions sharing the booze with the other men whilst, perversely, mentioning the girls could "share their body heat".

Once they arrive, he and the other detectives get to work investigating the Observatory when their proxy doesn't arrive. During this investigation, he gives an explanation on the type of telescope that goes there and pushes for the others to stay, assuming that this was merely a test. He teamed up with the detective, Shita Enbi, for another investigation, and when they reported back, Ko fell unconscious as a result of ingesting drugged cans of coffee that was given out during the van ride.

During his time unconscious, he was placed back in his room and was killed by Tadashi Asakura via dismemberment alongside, Eigo and Shiita. All three had their body parts switched with each other. After Tadashi's defeat, it was revealed that Kō was actually an arsonist who, as a detective, solved his own crimes to raise his DSC rank. Years ago, he was the serial arsonist that burned down multiple private homes in in a neighborhood and pinned the blame on an astrologist who, allegedly, committed suicide. At the time, he got away with it and received acclaim. Tadashi Asakura was one of the victims that had lost his family due to the arson and his legs had to be amputated. Because of this, Tadashi grew bitter and accepted the Duel Noir to get exact revenge on Ko.

Tadashi Asakura
As the culprit behind the arson which cost Tadashi his legs and his family, Tadashi despised Ko to the point he was willing to take up a Duel Noir just to kill him and avenge his family.

Eigo Amino
During the time at the Observatory, he became closest to Eigo, sharing a mentor-rookie relationship. While Eigo was initially hostile to Ko, the salaryman quickly began sucking up to him as a result of being a Class 3 detective. Ko used mainly used a way to show off his knowledge of the case and often calls Eigo a greenhorn.

Yui Samidare
When they first met, Yui was initially wary of Ko due to his appearance, but did grew to respect him after he displayed his competence as a detective. Despite this, his drunken behavior and tendency to display his common knowledge, caused Yui to not really like him. After it was revealed he was a serial arsonist in order to raise his rank, Yui was left horrified and in disgust on him.
