Triage X is an ongoing Manga series by Shouji Sato, of ''HighschoolOfTheDead'' fame. Drawn in his [[{{Fanservice}} typical style]], it depicts the actions of a hospital-themed vigilante team stationed at the Mochizuki General Hospital. Feautures [[EverythingsBetterWithMotorcycles motorcycles]], gunplay, StuffBlowingUp, and fanservice.

Though it has the Mochizuki team as protagonists, it mainly centers on Arashi Mikami, a teenaged vigilante assassin who received an organ transplant after Dr. Mochizuki's son Ryuu was declared brain dead after a terrorist attack took place at the International Medical Center in Bioka City. Even though he lost the things important to him, Arashi is prepared to make the best of it by combating crime in the city.

!!This series contains examples of:

* AmbiguouslyBi: Miki and Yuko. While the two of them are drunk out in the mountains, and on the phone with Mikoto, Miki starts groping Yuko, who only asks her to stop because in her own words "that's what I'm supposed to say right?", explaining that she and the men of Tobioka need to know if they're real. They then start insisting men are stupid, before switching their opinion and start screaming over the phone about how they need to go find a man.
* BadassCrew: Everyone in the main cast.
* BadassBiker: Arashi & Mikoto.
* {{BFG}}: Anything that Sayo uses be it a handheld [[GatlingGood Minigun]] or light machine guns, granted that she is [[TheBigGuy The Big Girl]] of the team & also [[BewareTheNiceOnes absolutely terrifying]] in [[PowerFist close combat]].
* ChildProdigy: Oriha started college at ''11''.
* ConvenientlyAnOrphan: Oriha is seen to be living in an abandoned mansion, loaded with explosive traps, the only "family" there for her is a large portrait of her mother.
* {{Crossover}}: With ''HighschoolOfTheDead'' in ''Lightning Pop''.
* DysfunctionJunction: All of the characters are confirmed to have had a major brush with death. Arashi nearly died, and would have had he not been given most of his best friend's body. Mikoto nearly died in a motorcycle accident, [[spoiler: the same one that killed her brother]]. Oriha is implied to have [[MissingMom lost her mother]], though how is unknown. It's not yet stated what the others' had happen.
* EverythingsBetterWithMotorcycles: The preferred method of entrance making for Arashi and Mikoto.
* {{Expy}}: Chikage Hizaki, especially in her full color experiences, looks almost exactly like Saeko Busujima from ''HighschoolOfTheDead'', Sato's previous series. If it weren't for the random tuft of hair on the side of her head that resembles a pointed up horn the characters would be almost identical.
* FanService: Tons of it.
* FieryCoverup: How our heroes obscure the evidence of their actions.
* ImpaledWithExtremePrejudice: One of the target's ends up this way after being shot and falling on the blades of a downed chopper.
* KillItWithFire: The primary assassination method of rival vigilante Pyrina.
* NeverFoundTheBody: [[spoiler: Chikage, despite her apparent suicide.]] Her equipment was recovered, but no body was identified as hers.
* OhCrap: Do not bother to shoot Arashi's motorbike helmet as it is totally bulletproof.
* ShoutOut: You can spot Dirty Harry in there, saying his "Do ya feel lucky, punk?" line.
** Effectively a FanService based version of {{Akumetsu}}
* StuffBlowingUp
* {{Tsundere}}: Mikoto to Arashi.
* [[VigilanteMan Vigilante Team]]: What the main characters are.
* [[WouldNotShootAGoodGuy Would Not Shoot A Non-Target]]: In Episode 12, Mikoto refrained from shooting Pyrina [[spoiler:a.k.a. Chikage Hizaki]], a rival vigilante who apparently would NOT have been so chivalrous if the initiative was reversed, because Pyrina has not yet been properly identified as a target.
