Ice Blade (地雷震, Jiraishin^?, lit. Earth-Lightning-Quake or Land mine-Shiver) is manga series written and illustrated by Tsutomu Takahashi, published in Kodansha's Afternoon magazine from 1992 to 1999. It was announced by Afternoon's October magazine that a new Jiraishin series would be in the magazine good! Afternoon and would be known as Jiraishin Diablo, which is currently being serialized in the said magazine.

The story follows Kyoya Ida, a plainclothes police officer, and his colleagues at the Shinjuku Police Department as they investigate and solve crimes in the Greater Tokyo Area. Sometimes, these crimes are solved with some prices to pay. Later on in Diablo, it portrays Ida and his interactions with various people after his absence from the force due to an eye disease while getting wind of mysterious deaths of villagers living in the fictional Amakura Island in Japan's Ishikawa Prefecture in the year 2008 while assisting a police detective in initially trying to figure out who or what was responsible for their deaths after it was reported back in 2007.

Kyoya Ida is a hard-nosed detective from the Shinjuku Police precinct, known to use lethal force to solve cases whenever they need to be solved. He works in a bleak, gritty representation of Shinjuku alongside his partner Tsuyoshi Yamaki in hunting down suspects and arresting them before he was killed in the line of duty. Ida was later assigned to another partner named Eriko Aizawa, the two working together to solve cases pertaining to the city's interests.

In the year 2008, Ida was beginning to suffer from the effects of after leaving the police force. He later gets wind of mysterious deaths of an unknown plague that killed the villagers in Ishikawa Prefecture's Amakura Island when he meets up with Taichi Kogure, a detective of the Ishikawa Police precinct and a now grown up Aya Koike, who is a known information handler in the underworld.
