Kurokami

Kurokami is a manga created entirely by the Manhwa team led by both Dalyoung Lim (story) and Sung-Woo Park (art).

Have you ever seen someone who looked a lot like you and determined "Hey! That's my doppelganger!"? Well, imagine if that person was a part of you. And imagine if, after making contact with that person, you'd die the next day. Oh, and also, it's called a "doppeliner".

Keita Ibuki is either a struggling computer programmer or an Ordinary High School Student, depending on whether you're reading the manga or watching the anime. Anyway, he takes pity on a hungry girl named Kuro and gives her some free ramen, earning her gratitude. It turns out that Kuro is a Tera Guardian, a being meant to protect the balance of existence. After Keita is injured by a Tribal End (an evil human), Kuro switches hearts with him, linking them forever...

The English dub is currently watchable on Bandai Entertainment's YouTube page in America. The manga is available in English under the title Black God.

Tropes:

 * Badass: All of the characters with fighting capablility, both heroes & villains.
 * Badass Adorable: Kuro, definitely.
 * Badass Grandpa: Keita's grandfather is a martial arts master who took down a Tera Guardian by himself.
 * Barbie Doll Anatomy: In the power-up sequence
 * Bittersweet Ending: The anime.
 * Calling Your Attacks: "EXCEED . . . MEGA-EXE!" It is mildly subverted in the anime as well when Keita activates his Thousand, he just yells "GO!"
 * Clap Your Hands If You Believe: In a side story, a Korean shamaness attempts to call the gods to help her with an exorcism, wondering why she's not getting an answer. She doesn't realize that there already is a god right there, Nam.
 * Curb Stomp Battle: Nam took out 32 Tribal Ends without even bothering to stop eating. This was shortly after she completely pwned Kuro with about the same amount of effort. The lady is Badass.
 * Cute Bruiser: Kuro.
 * Dark Is Not Evil: Steiner, Bernhard, and the rest of the German High Council wear these ominous black coats. They're some of the protagonists' strongest allies.
 * The Dragon: Hiyou, at least in the manga
 * Emotionless Girl: Excel.
 * Eyes Always Shut: Toshiro
 * Family Unfriendly Death: Poor, poor Mayu.
 * Fire, Ice, Lightning: The Masagami are fire and ice, along with
 * Genki Girl: Kuro, so very much
 * Gory Discretion Shot: Subverted everywhere. None of the beatdowns Kuro takes are censored. Surprising, given that most are given by larger, male opponents.
 * The first Tribal End introduced, Also not censored.
 * Also, Mayu
 * Heroic Sacrifice: In the manga,
 * Heterosexual Life Partners: Daichi and Raiga.
 * Hey Its That Voice: Gee, where have I heard Steve Blum, Crispin Freeman or Mary Elizabeth McGlynn before?
 * And Jason Griffith as Keita.
 * And Laura Bailey as Kuro.
 * And Stephanie Sheh as Excel
 * Hot Amazon: Mikami. Her Exceed when activated makes her even faster and stronger than she already was.
 * Huge Guy Tiny Girl: Steiner and Excel
 * I'm Taking Her Home With Me!: Kuro. Seriously, she's adorable, innocent, kind-hearted & a REALLY handy partner when in a fight.
 * Instant Expert: Nam achieves a surprising amount of fluency in Japanese just by finding a phrasebook.
 * Jerkass: Keita, especially in the manga given how he treats Kuro & most people at first.
 * Jerk With a Heart of Gold: Keita somewhat. Akane pretty much describes him exactly this way when Kuro asks for the first time. He matures into his role as Kuro's partner, genuinely caring for her but still frequently abuses her for no reason.
 * Subverted in the anime since in that version Keita is a more openly likable and emotional guy, though.
 * Lightning Bruiser: Steiner, especially when his Exceed activates.
 * Love Triangle: Manga shows this between DAMN IT, BE A MAN, DUDE!!
 * Megaton Punch: Kuro's Mega-Exe, after episode 16, and last but definitely not least.
 * Never the Selves Shall Meet: A central theme of the story in either incarnation.
 * New Powers As the Plot Demands: in anime
 * Non Action Guy: Keita is this until he gets his Thousand, and even then he generally hangs in the back and lets Kuro do the physical fighting.
 * No Social Skills: Kuro
 * Overtook the Manga: The anime loosely followed the manga's storyline at first but the 2nd half in particular has nothing to do with the source material.
 * The doppeliner system is different. In the manga, the two dies if they see each other, the remaining one becomes a root. In the anime, the root who has more luck then any other survives by default. This major difference actually caused incompatibility of the entire plots of both versions.
 * Pretty Freeloader: Nam and Kuro
 * Rocks Fall Everybody Dies: Subverted/averted in the anime.
 * Scenery Porn: Okinawa and The Pure Place are depicted as unusually gorgeous.
 * Screw Destiny: Deconstructed in the manga.
 * Shown Their Work: You'd never guess from reading the manga that nobody on the team ever actually set foot in Japan or can speak Japanese. The original script is written in Korean then translated in Japanese.
 * Sink or Swim Mentor/ Training From Hell: In the manga, to help Kuro and Keita achieve more power, first Nam sealed most of Kuro's power, then makes them face their worst nightmare, Motsumitama that have curbstomp Kuro. Granted, it was just illusion, but Kuro almost cut her own tongue to save Keita....
 * Smug Snake: Hiyou
 * Squishy Wizard: Keita, when he's not being a Non Action Guy. Well, squishy compared to Kuro, anyway.
 * Standard Female Grab Area: Subverted. Kuro breaks out of various Mooks' hammerlocks with laughable frequency.
 * Team Pet: Punipuni, Kuro's puppy
 * Theme Music Power Up: About a third into episode 22, the first intro theme plays in the background. Ass kicking ensues.

 * Tyop On the Cover: "DESTORY DESTINY!"
 * Victorious Childhood Friend: Akane (anime version only).
 * Would Hit a Girl: Kuro gets punched, kicked, choked, and slammed face-first into and through tables. Often by Keita.
 * Also what is done to Makana.
 * You Can't Fight Fate: Subverted: spends the whole anime trying to avert  fate, which is.
 * You Can't Fight Fate: Subverted: spends the whole anime trying to avert  fate, which is.
