Yakushiji Ryōko no Kaiki Jikenbo (薬師寺涼子の怪奇事件簿 ?, lit. "Ryōko Yakushiji's Strange Case Files") is a series that consist of TV anime, manga and light novels created by Yoshiki Tanaka and illustrated by Narumi Kakinouchi. Two Drama CDs had also been released prior to the anime adaptation with different seiyū from the CD and the TV version.

The series centers around Ryōko Yakushiji, an elite police officer with the Tokyo Metropolitan Police Department who had graduated from Tokyo University under its Law Faculty. She is involved with her subordinate Junichirō Izumida as they investigate cases that pertain to the paranormal and supernatural when and if they cannot be investigated with modern science.

As the light novels, manga, drama CDs and anime adaptation have different plots and paranormal events/creatures, their central plots are most of the time different from each other.



Ryōko Yakushiji, a Superintendent in the Tokyo Metropolitan Police Department and a graduate of Tokyo University's Law Faculty and a multilingual person, works with Junichirō Izumida to investigate seemingly paranormal, supernatural or bizarre events that get involved in criminal cases. Ryōko works with her colleagues and subordinates, including her rival Yukiko Muromachi, alongside JACES security forces personnel and her personal maids Lucienne and Marianne to resolve the cases before they go out of hand.

The following are rogues monsters/creatures that have appeared in the anime[6]

Giant Snake

Making its appearance in the Babylon building in Ginza, it was created as a result of ingesting various growth hormones. It died when the building was destroyed in an explosion.


It's not known how they appeared, but they had apparently showed up in the digital copies of the journalists' cameras.

Unknown Alpha Human

Created as a result of combining human sperm/egg cells with DNA from an unknown prehistoric human, it resulted in the creation of a monstrous alpha human that killed several yakuza assassins before it would die of rapid cell degeneration.

Centipede Robot

A counter-terrorist robot created by the JPP, it went rogue after a traffic accident result in an altercation of its defense systems that recognizes anyone with a dangerous object as an enemy. Ryoko defeats it by shooting its main sensor. It was later used by the JPP as a means of eliminating Ryoko and Junichiro.

Mutant Mangrove Seeds

Said to be caused by secret experiments of JPP scientists, they were able to possess Ryojin Tadomura and a faction of the JPP before Marianne destroys the mutant mangrove tree with napalm grenades.

Unknown Cricket

Discovered by an unknown person, this species has the ability to resonate soundwaves that are equal or greater than the soundwaves on cellphones. This results in making people commit suicide when they use their cellphones at the same time the crickets resonate the said soundwaves at the same time.



Owned by the Yakushiji family, it's a security company that ex-police officers both enlisted and high-ranking are employed into after their retirement. JACES is well-known as one of Asia's best security companies. Its personnel use gray for their uniform color.

In combat operations, they use PASGT ballistic helmets, gray BDUs, tactical vests and light to medium body armor. JACES personnel are armed with expandable baton sticks when they encounter unarmed people.

Its origins are traced back to the end of World War II when the Japanese Empire Security Service was established before it became JACES.

Japan Private Police

Known as the Nippon Private Police (日本の私用警察 nihonnoshiyokeisatsu ?), it was founded by ex-Diet member Ryojin Tadomura and heavily funded by the Government of Japan to counter the influence of JACES in the domestic and international security market. They are known to be hired in war-torn countries after military forces are pulled back, conducting police duties in their place. JPP personnel are also hired as private security guards. JPP uses green as its color as evident in their uniforms.

Tadomura was, however, killed when mutant mangrove vivipary seeds were embedded in his body. The will of the genetically enhanced plants had destroyed his living will as they had spread throughout his entire body. It's unknown who the CEO is after Marianne fired napalm grenades at his Okinawa villa to prevent the rogue seeds from spreading on the entire Okinawan island and to kill him to prevent him from infecting others.

During combat operations, JPP personnel are identified with green heavy body armor, anti-riot helmets and are armed with mostly Howa Type 89 assault rifles, Heckler & Koch MP5 and Minebea PM-9 submachine guns with expandable baton sticks. In normal operations, JPP personnel operate as private guards and sometimes, deploy robot droids to help them conduct searches and patrols with/for them.


Located in the Greater Tokyo Area, it is said to house several departments of the Tokyo Metropolitan Police Department that operate under secret circumstances for covert missions.
