Jun'ichirō Tanizaki

Junichirou Tanizaki (谷崎 潤一郎,) is a member of the Armed Detective Company and the brother of Naomi.

Appearance
Tanizaki has a slim, average build with orange hair, hazel eyes, and pale skin. His hair is parted in the middle with its spikes sweeping downwards, along with a light grey bobby pin clipped on his left. He wears earrings with the corresponding colour of his pin.

His attire consists of an oversized, off-white V-necked sweater with a black stripe on the collar, light blue pants, and brown shoes. A red sweater is wrapped around his waist. In the manga, Tanizaki also dons a black tank top underneath his sweater.

Personality
Tanizaki is shown to be the humble and somewhat carefree type, yet he will get violent towards those who hurt Naomi. He tends to get embarrassed by his sister's antics and physical intimacy, but nonetheless cares deeply for her. He even states that things such as morality, ego, and pride do not matter to him compared to Naomi. He also cares for the wellbeing of his fellow Agency members.

He is very friendly and arguably one of the most "normal" members of the Agency, not being eccentric or loud like any of the other members though he does go along with their shenanigans. He is also shown to be a close friend to Atsushi, primarily because the two seem to be the more "normal" members of the Agency, and the two work together on a few cases and can fight tough opponents as a productive team, such as their fight against Lucy Maud Montgomery. Like Atsushi, he can also get nervous and be a bit of a scaredy cat (though is not cowardly) like when he was nervous flying a plane by himself.

Ability
His ability, Light Snow (細雪,), allows him to project illusions in a certain range of area around him, covering the affected area with snowfall.

Background
Tanizaki lives alone with his little sister Naomi. Nothing has been revealed about their past yet, or what has happened to their parents.

During chapter 3 when Atsushi is guessing what each character did before joining the Armed Detective Company, he correctly guesses that they were both students.

Plot
In the anime, when Atsushi trusted Dazai to find him a job, it was revealed that Tanizaki posed as a villain. During this time, he held a woman captive and he also had a false bomb on him. This entire ordeal served as Atsushi's test. It was stated by Tanizaki's younger sister that he played the villain card well.

After the incident, Tanizaki apologized to Atsushi, saying that even if it was for Atsushi's exam, he was still rude to him. This fact shows off how much of a caring person Tanizaki can be. It was also when he had told Atsushi that he too worked as an assistant of sorts at the agency.

Trivia

 * He, along with several other characters, made an appearace in the mobile game Love Heaven as a limited time character.
 * Tanizaki's dislike of earthquakes may be a nod to his real life counterpart who had a lifelong fear of earthquakes due to his home being destroyed by the 1894 Meiji Tokyo earthquake that destroyed several major cities including Yokohama.
 * Jun 'ichiro Tanizaki's author counterpart was a novelist who was inspired by and wrote about a vast variety of topics but is noted most prominently for his sexual fantasies and charismatic female protagonists that he created (also a likely influence for the behavior of Naomi, who is named after one such protagonist). His ability is named after his novel on the lives and social state of three sisters during the war, named Sasameyuki (light snow) but translated as The Makioka Sisters in English, due to difficulty in translating the intricacies of the Japanese title appropriately.
