Shion Ryuguu

Shion Ryuguu, CODENAME: TOXIN, is a Necros Synthetic

Mission
Ryuguu was one of many Necros Synthetics deployed behind UNSC lines to cause general chaos, demoralize, and spread fear amongst the population through random murders and bombings. Ryuguu was deployed to the area of Tokyo, Japan. Ryuguu was responsible at least 75 murders in the area, as well as a dozen bombings, killing at least 100 civilians, a dozen police officers and three UNSC military personnel before she was killed by Kouta Hirano and Saeko Ryougi.

Favored Weapons and Methods
Ryuguu for the most part preferred to use melee weapons, both her chain wrist blade as well as countless other melee weapons including several different knives, a machete, a steel pipe, a crowbar, a baseball bat, a katana, and a a chainsaw. Ryuguu tended only to use firearms if she was attacked by someone who had a gun. Thus Ryuguu used only two different firearms in her killing spree, either her wrist mounted pulse machine pistol or an M57 she scavenged off a police officer. Ryuguu also was involved in 12 bombings, including one that claimed the lives of three UNSC soldiers and a several civilians. Her bombs were crude improvised devices using any type of explosive available, typically black powder.

Trivia

 * Her name is a composite of two characters in the extremely violent anime Higurashi No Naku Koro Ni, Shion Sonozaki and Rena Ryuguu, though she looks like neither of them.
 * Shion Ryuguu was inspired by the "violent anime girl" stock character.
