Twelve is one of two members of a terrorist group known as Sphinx, working with Nine as his primary partner. He and [Nine](https://anilist.co/character/88094/Nine) grew up together in an institution for children known as the Settlement, and engaged in terrorist activities, with unknown motives.

On the outside, he's a typical jokester: light-humored and energetic, enjoying messing around in other people's business. However, he is fully capable and willing to adopt ruthless and violent methods if the situation calls for it. This contradictory set of personality traits are the result of the psychological damage sustained during his stay at the aforementioned children's institution. Nonetheless, he is a loyal and dependable friend, has a genius mind and a keen sense of social justice. He also has a compassionate side, as evidenced by his interactions with [Lisa Mishima](https://anilist.co/character/88095/Lisa-Mishima).

~!Twelve changes dramatically upon interacting with Lisa Mishima. When she runs away, he goes after her against Nine's wishes. He is made by [Five](https://anilist.co/character/88301/Five) to choose between saving Lisa and betraying Nine, and ultimately chooses to save Lisa. However, he later helps Nine out of a sticky situation at great risk to himself.

In the final episode, shortly after he, Nine and Lisa are reunited, he is shot and killed by the American government.!~

Painted in red, the word "VON" is all that is left behind after a terrorist attack on a nuclear facility in Japan. The government is shattered by their inability to act, and the police are left frantically searching for ways to crack down the perpetrators. The public are clueless—until, six months later, a strange video makes its way onto the internet. In it, two teenage boys who identify themselves only as "Sphinx" directly challenge the police, threatening to cause destruction and mayhem across Tokyo. Unable to stop the mass panic quickly spreading through the city and desperate for any leads in their investigation, the police struggle to act effectively against these terrorists, with Detective Kenjirou Shibazaki caught in the middle of it all. 
 
Zankyou no Terror tells the story of Nine and Twelve, the two boys behind the masked figures of Sphinx. They should not exist, yet they stand strong in a world of deception and secrets while they make the city fall around them, all in the hopes of burying their own tragic truth.
