'''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 when a terrorist attack took place at the International Medical Center in Tobioka 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.

The series consist of a manga and an anime adaptation that aired in April 2015.

* ActionPrologue: One is shown at the beginning of episode 1.
* 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.
* AnArmAndALeg: A tv station crewmember is shot in the leg by a terrorist in episode 5.
* AssholeVictim: Pretty much anyone killed by the main characters. They will often be seen in a KickTheDog moment to further justify the main characters killing them.
* BadassCrew: Everyone in the main cast.
* BoomHeadshot:
** Chikage is shot in the head with a crossbow bolt in episode 4. Though she survives it, she kills herself shortly afterward by jumping into the burning building.
** An idol singer suffers this in episode 5 from a terrorist.
* CarFu: Mikoto and Arashi make use of this with their motorcycle from time to time.
* CodeName: The protagonists' organization classifies people they deal with using medicine-themed terms, from "Fever" (minor nuisances that amount to no tangible threat to Tobioka City) to different types of "Black Label" (criminals so vile that they need to die for the good of the city but untouchable to conventional law and justice) such as "Malignant Tumor".
* {{Crossover}}: With ''HighschoolOfTheDead'' in ''Lightning Pop''.
* DieHardOnAnX: Episode 5 has terrorists hijack an idol concert with Oriha attempting to fight off the terrorists. Episode 6 will continue from this.
* 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.
* FanService: Tons of it.
* FieryCoverup: How our heroes obscure the evidence of their actions.
* {{Gainaxing}}: Done from time to time in the anime, especially because almost all of the female characters have rather large breasts.
* ImpaledWithExtremePrejudice: One of the target's ends up this way after being shot and falling on the blades of a downed chopper.
* HostageSituation: Occurs regularly throughout the show, such as when the terrorists take over a tv station in episode 5.
* MortonsFork: The people with explosive vests strapped to them in episode 4. They are told that if they can kill Mikoto, the gang leader would let them live, but if they don't, he would set their vests off. Chikage tells them he probably wouldn't hold up that promise had they of succeeded.
* OhCrap: Do not bother to shoot Arashi's motorbike helmet as it is totally bulletproof.
* ShoutOut: You can spot Film/DirtyHarry in there, saying his "Do ya feel lucky, punk?" line.
** Effectively a FanService based version of ''Manga/{{Akumetsu}}''.
* StuffBlowingUp: Done on a regular basis in the show.
* TyopOnTheCover: The "Monte Calro SS" restaurant Arashi visits in the first episode. It was probably supposed to say "Monte Carlo SS"
* [[VigilanteMan Vigilante Team]]: What the main characters are.
* WhamEpisode: Episode 5, in which a group of terrorists take over a tv station, then kills an idol singer to prove they're serious.
* WhereTheHellIsSpringfield: Tobioka City's location in Japan is unknown.
* WouldHitAGirl: The terrorist leader in episode 5 shoots an idol singer in the head to show the cops that he means business. A man in a bear suit similarly attempts to attack Oriha and the other girls wit her, forcing them to fight back.
