* BigBad: Of the final arc.

One of the two police officers assigned to solve the mystery of Yako's father's death. Later becoming one of Yako's best allies, partly because his partner at the time turned out to be the murderer. Cool, collective but really weird in his own way. He lost his family to X and was one of the first to be hit by him, [[spoiler: but later on it's revealed this was Sicks' doing.]]

* SmokingIsCool: Even in a hospital.
* SpitTake / EyeTake: Had a spit take when Yako appeared crashing Aya Asia's concert, then later had an eye take when he saw the commercial she was in at the beginning of Chapter 39.

* TheCracker / PlayfulHacker: For three days, the Police Department website was replaced with the "sakuradamon Department Store", with each department and member replaced with a lookalike shop and employee. The Investigation department was made into the {{Fundoshi}} Shop and Sasazuka recalls Ishigaki being turned into the "Fundoshi Wine Steward". The Police Department retaliated by allowing it to continue until they could absolutely catch Higuchi.

* [[spoiler:YouAreNumberSix: His name, X, was originally XI, the Roman Numeral for Eleven; he was the Eleventh clone of Sicks.]]

X's partner in crime, Ai is usually in a servant/straight-man relationship with him. We say "usually" because her role changes from day to day, depending on who X is impersonating. It's because of Ai that X is known as a thief, but she's stated that her house is becoming filled with "B-grade goods" like wooden bear statues ever since X gained an interest in Neuro. [[spoiler: Before becoming Ai, she was "Plane Crasher Imina" who bombed or poisoned planes. When the New Bloodline arc began, Ai was killed by Sicks and X was captured to become XI.]]

* HeelFaceTurn: After Yako solves her case on-stage, and reveals Aya's motivations for doing so, Aya willingly turns herself over to the police. She starts to reform during her time in prison and becomes Yako's ally.
** The anime changes the scene somewhat, however, making Yako's reveal cause the "puzzle" Neuro feasts on the disappear...somehow.

* TookALevelInBadass: Before she was incarcerated, Aya needed to feel a sense of loss to influence others. Once Yako put her soul and mind to rest, her voice becomes nigh on a force of nature, influencing the guards at her jail, officers of the state, and even insects and plants. The only reason she doesn't control the entire building is simply that she doesn't want to.
** In a sense, she also inspired one in Yako, showcasing the start of Yako's abilities to understand people.

Harukawa was a neurologist, who cloned himself to create HAL; a super advance A.I who plotted to take over the world with an Electronic Drug, which brainwashed the masses via hacking televisions and computers to display the drug. [[spoiler: While Eisuke was killed when HAL revolted, HAL himself was later taken down when Neuro trashed his defense system and devoured his mystery, and then uninstalled by Yako.]]

* NiceJobFixingItVillain:
** Had he kept Yako and Neuro from investigating the crime scene, Neuro wouldn't have had such an easy time solving the case. It's rather notable because Sasazuka was ''against'' Yako investigating the scene, meaning there would be precedent to restrict her access.
** That said, it's debatable at how much an impact this would have made, given said crime was solved at Neuro's most powerful state and Neuro hardly follows normal restrictions anyways.

* EvenEvilHasLovedOnes: They do love each other.

* HeelFaceTurn: Post CurbStompBattle from Neuro.

* AnimalMotif:
** [[OurDragonsAreDifferent Dragon]] or at least he thinks so.
** Neuro, on the other hand, thinks its closer to a tick
* AssholeVictim: [[spoiler:He is killed by Kasai [[YouHaveFailedMe for failing to kill Neuro]], but doesn't earn a lot of sympathy with his passing, considering how he unrepentantly slaughtered thousands of people with his flooding]]
* TheDragon: Averted, [[SmallNameBigEgo he thinks he's this]], but Kasai fits the role much closer
* FauxAffablyEvil: He seems to be gentlemanly at first, then some ignorant thugs accuse him of stereotypes

* KillAllHumans: He offers to have hundreds of thousands of humans to be killed in the following flooding act, he actually succeeds on a large scale, but doesn't reach the number he was estimating
* MakingASplash: Not an actual superpower per se, the collective knowledge of thousands of years of flood building knowledge allows him to cause the greatest amount of damage possible

* SmallNameBigEgo: While he is an extremely competent HeroKiller in his own right, he assumes that he is in fact, TheDragon, when TheDarkChick suits him much better as a role
* VillainousBreakdown: When Neuro uses his sadism tool on him, he cracks epically
* WrongGenreSavvy: While he is a successful HeroKiller on city size scale, he assumes that not only is he stronger than Neuro because he isn't fighting back, but that he is TheDragon as well. Neuro proves these to wrong with his defeat

* AmbiguouslyBrown: He's established to be of Indian descent on his mother's side
* AntiVillain: By far the most sympathetic of the Five Fingers, Type II easily

* HoistByHisOwnPetard: Neuro notes that she should've fought herself for two reasons, 1) being on the defensive weakens him greatly and 2) one of her thrown away {{Mook}}s helps Yako destroy the bomb implanted in the base

* PsychoSupporter: To Sicks [[spoiler: later Neuro after he brainwashes her]]
* TheSmurfettePrinciple: The only girl in the Five Fingers

* UndyingLoyalty: To Sicks [[spoiler: enough to be driven to suicide even after being brainwashed]]

* VillainousValor: [[spoiler: Even after being brainwashed by Neuro, she decides to kill herself in order to protect Sicks' location]]

* AwesomeByAnalysis: While the other Five Fingers have extensive knowledge on elements to help with their powers, his knowledge on fire alone makes him able to create technology to utilize it to its full potential [[spoiler: without having to alter his body in any way to do so, especially not with X's DNA]]
* AxCrazy: Despite being normal for the most part, he revels in the destruction his fires cause
* BadassNormal: Sicks' right-hand man and all of his pyrokinetics comes from extensive knowledge on fire rather than supernatural powers [[spoiler: and is thus one of the two members of the Five Fingers to have never used X's DNA or any alterations to enhance their power]]

* EvilUncle: To a reformed pyromaniac, Homura
* GoodSmokingEvilSmoking: And gives a great quote for this that counts as a HeWhoFightsMonsters speech [[spoiler: which describes Sasazuka's true personality]]

* OnlySaneMan: To the True Bloodline's more unstable members, but he' mostly this to Genuine and Tierra; but especially [[BewareTheSillyOnes Tierra]]
* PlayingWithFire[=/=]KillItWithFire: He uses a complex series of tubes on his body to create flames and eject them towards his targets, [[BadassNormal making him essentially a normal man with extensive knowledge on fire]] when compared to his [[PersonOfMassDestruction allies]]

* TheStarscream: Has made an attempt to kill Sicks at one point and is not as fanatically loyal as the other agents

** Yako's father was killed via his head being cut off with a chainsaw, and his blood was used to paint the walls. Since there was no way to enter the room, it was ruled a suicide by the police.
** Only in the anime. In the manga, his body was pincushioned with knives. And in the manga, the police don't think it's suicide, obviously.

* GoodParents[=/=]AbusiveParents: Zig-zagged between these two tropes since Yako obviously loved him very much (to the point she didn't feel hungry when he died, something she only does when she's in extreme depression), but on occasions, we have flashbacks to his not-so-good-parenting behaviors (like how he looked down on Yako for not book-smart enough or abandoned her at the port alone with only some money for tickets just because she was better at fishing than him).

* {{Fatbastard}}: Especially with his DomesticAbuse
* HappilyMarried: Believe it or not, though [[DomesticAbuse it does have its problems]]

* TooDumbToLive: His main trait. The guy had the deadly habit of finding and growing talents in people but he never thought about actually control them. It usually ends with people turn against him (like the Hayasaka brothers) or gradually takes over his business with him being the PuppetKing (like Godai). A bit unusual for this trope, he actually benefited from this (after almost losing his life) and now enjoying playing video games all day while making Godai do all the works for him.

* CloudcuckoolandersMinder: [[spoiler: To her father]].

* TogetherInDeath: [[spoiler: with HAL]].

* ComedicLolicon: Play for laughs. His antics around children constantly freak people out or makes them consider calling the police.

* CampGay: She's this if the {{Guyliner}} didn't clue you.

* YourFavorite: Invites Neuro to meet with him, and [[spoiler: tries to arrange a meal for him by forcing several people to kill, right there, by threatening their families and so on. He's wrong in that it's not the mystery itself Neuro eats, but the psychic energy of the motivation behind it, the twistedness that would drive someone to commit murder and try to hide it. Sicks's sick little tableau was the equivalent of offering a starving man Syrup of Ipecac. And then, since they hadn't pleased Neuro, he killed all of them, meaning that they would never be able to produce a real mystery]]. At that point, the reader learns how Neuro acts when he's really, really angry.

* NoPronunciationGuide: The reason his name is pronounced "''sigh''" instead of "''ecks''" and despite his name being consistently spelled "X" is because his name was first called "Monster Robber Xi" by a foreign media: ''X'' for the unknown, ''I'' for the invisible. When pronounced in English, it becomes "Sai". [[spoiler: "Xi" also stands for "11" in Japanese, see the last trope.]]
** For those confused, by the way, as to why "X" = Unknown, it traces back to language. However, there are about three roots:
*** Arabic into Old Spanish: The word "šay'", pronounced "shey", means "something" in Arabic. When Spain scholars were tasked to turn Arabic into Old Spanish, they found they couldn't directly translate "šay'" due to the fact that the hard "sh" sound it needs didn't exist in their language. To get around it, they translated "šay'" into "xei", which became shorted to the letter "X".
*** Greek: There are two Greek letters that use X. "Xi", which is pronounced "sai" in English, and the letter Chi which is rendered as "X". The Greek word "xenos" means "unknown", more or less for strangers or foreigners than the ''actual'' unknown.
*** Latin and math: Latin actually has its roots tied directly to the Arabic into Old Spanish written above. When the Arabic word for "something" became "x", the Latin language took it up and used it in Algebra to denote unknown numbers.

* SempaiKohai: While never calling anyone "Kohai", Jun almost always refers to Sasazuka as "Sempai". [[spoiler: Later, when Sasazuka dies, Jun takes up the title of "Sempai" in his partnership with Todoroki.]]

* SempaiKohai: Calls Sasazuka "Sempai" [[spoiler: and later names himself "Sempai" when Sasazuka dies.]]
