History Manga / ChaosicRune

* BleachedUnderpants: Kenji Yamamoto, the author of this series, got his start drawing ero-guro hentai and has since returned to drawing hentai. Considering the brutality of this manga, it's not too surprising.

There is a sequel, and [[DarkerAndEdgier it is even more bloody]]. Unfortunately, the sequel seems to be on indefinite hiatus since no new chapters have been released in many years.

* DeaderThanDead: Anything and anyone eaten by Death Rex Head is explicitly ''gone'', utterly and completely annihilated, body, mind and soul. And Death Rex [[OmnicidalManiac wants nothing so much as to devour everyone and everything]].

* VerbalTic: A running gag (possibly from the translators) in this series, several villains tend to have a sort of mad libs catchphrase. Examples include "Have you ever seen the movie X? I haven't, but it's kind of like that."

* {{Gorn}}

There is a sequel, and [[DarkerAndEdgier it is even more bloody]].

* DraconicAbomination: Death Rex, whether whole or its individual pieces, is an all-devouring draconic monster. Other powerful "Dragon"-type monster can qualify as well.

* EldritchAbomination: Death Rex, whether whole or its individual pieces. Other powerful "Dragon"-type monster can qualify as well.

* ShoutOut: To ''Anime/YuGiOh''. One of the early minor villains has a habit of comparing what he is about to do to scenes from popular movies, and is killed in a salute to the ''{{Alien}}'' franchise.

* GrimDark: The protagonist believes he ate his parents. The TokenMiniMoe of the team starts off wanting to murder the hero, believing he's the one [[YouKilledMyFather who killed her brother]]. After the first arc, mass murders tend to occur every time a new villain appears. It's like if someone took the GrimDark out of [[TabletopGame/{{Warhammer 40000}} Warhammer 40k]] and put it in a playing card game series.

* MechaMooks: The Machine Society's card monsters fall under this category.

* TheMole: [[spoiler: The secretary of the Machine Society's Japanese branch president is Magic Society/Clan member Tatsumi Kumashiro.]]

* ShoutOut: To YuGiOh. One of the early minor villains has a habit of comparing what he is about to do to scenes from popular movies, and is killed in a salute to the ''{{Alien}}'' franchise.

The story begins with the protagonist angsting over the death of his parents in a plane crash. The primary cause of said angst is that he was the only survivor of that crash, and the remains of everyone else had been ''eaten.'' A mysterious man invites the hero to come with him, claiming to have the answers to the questions the young man has. The young man is taken to a facility up in the mountains, and is placed in a room with several other young men. A set of cards is dropped into the room, and the first person that picks up a card suddenly has a monster emerge from his guts. This person has the monster go on a killing spree, and soon a battle royale begins. What is going on with all these strange cards? Where are these monsters coming from? [[WebVideo/YuGiOhTheAbridgedSeries And why does this seem eerily similar to a children's card game?]]

* CannibalismSuperpower: Death Rex. Look down at MegaManning for the first half of his powers. The second half is that by eating people or monsters, Death Rex heals his controller.
* DeaderThanDead: Anything and anyone eaten by Death Rex is explicitly ''gone'', utterly and completely annihilated, body, mind and soul. And Death Rex [[OmnicidalManiac wants nothing so much as to devour everyone and everything]].

* EldritchAbomination: Death Rex, whether whole or its individual pieces. Other powerful "Dragon" type monster can qualify as well.

* HumanoidAbomination: "Magic"-type monsters.
* InfinityMinusOneSword: Death Rex, the protagonist's strongest creature, is normally an InfinityPlusOneSword, but was divided into pieces, each one incredibly powerful, and each piece wanting to be the dominant part when they come back together (several of the pieces blame the head and mouth, the piece that the hero has, for their being divided in the first place).

* MegaManning: Death Rex, once he defeats a former part of himself, allows the hero to summon that part of Death Rex. And if Death Rex devours a monster, the hero gets a card allowing him to grant Death Rex with that creature's power for a short time.
* MindRape / MoreThanMindControl / BrainwashedAndCrazy: When the main character fights against Death Rex in order to establish dominance, Death Rex doesn't even need to attack: he violates the hero's mind until the kid goes temporarily insane, decides to end it all, and just has Death Rex go on a rampage (which is what Death Rex wants to do anyways).

* OurDragonsAreDifferent: "Dragon"-type monsters, which tend to not look at all like something you'd consider a dragon, bur more like StarfishAlien bioengineered living weapons; the strongest one, Death Rex, as well as its separate parts, is a full-fledged EldritchAbomination.
* RatedMForManly: Excessive gory deaths, big muscular men, well endowed women, cards that summon weapons such as swords, pistols, and shotguns. They may as well call this series "Testosterone: The Card Game".

* ExtremeOmnivore: Death Rex. He can eat '''everything''', and if he eats something, it disappears completely from the world. This means that if he eats an opponent's monster, that monster's controller disappears as well.

* HumanoidAbomination: "Magic" type monsters.

* GrimDark: The protagonist believes he ate his parents. The TokenMiniMoe of the team starts off wanting to murder the hero, believing he's the one [[YouKilledMyFather who killed her brother]]. After the first arc, mass murders tend to occur every time a new villain appears. It's like if someone took the GrimDark out of [[{{Warhammer 40000}} Warhammer 40k]] and put it in a playing card game series.

* CompleteMonster: Death Rex. He makes no attempt to hide the fact that what he really wants is to consume everything. That means everything, everywhere, everywhen. The only reason he can't is because he's incomplete. And the only thing keeping Death Rex under control is the hero's willpower, and that fails at least once during the series, with nightmarish results.
