Beyond Birthday fanfictions
This is dedicated to bbxkira, who specifically requested for horror/gory Beyond Birthday fanfictions without too much BB/L romance. These are not romance, so much as horror. Light Yagami as Kira plays a major role in most of them.
Scarlet Letter by RobinRocks: Possibly the best fanfiction in which B is a main character. BxLxLight. It’s pure horror. The writing is excellent, 100% recommended.
Butterfly Caught: BBxLight. Very interesting, and very smutty. Recommended if you’re 18+ only, please. One of the smuttiest fics in the whole fandom, I think (along with Nights). Romance/Horror.
Also, from the writer of Butterfly Caught, there are four more BBxLight one shots:
Syrup (includes L as well, I think it’s a threesome)
Tease
Elevator
Confessional & Neko
Warning: Those works are extremely smutty. Literal porn. Mature audiences only. Please don’t read if you’re below 18.
Act Minus: Glass Slipper (Chapter 20 of Poison Apple): This chapter is dedicated to Beyond Birthday, and it doesn’t have much to do with the original story of Poison Apple. It analyses Beyond Birthday’s character, and deals with his past, his psychological trauma, his motives to kill.. It’s genius and 100% canon. RECOMMENDED IF YOU WANT TO EXPLORE BEYOND BIRTHDAY’S CHARACTER. SPOILERS TO DEATH NOTE: ANOTHER NOTE. Perfect writing. READ THIS.
What’s My Name?: Starring L and Beyond Birthday but with no romance because it’s pure horror. Rated for disturbing imagery, language, psychological trauma and gore.
I Disappear: A one shot from the writer of Genius is a Curse; deals with what happened to Beyond Birthday in canon, after his trial and how he was killed by Kira. 100% canon and very nice. Angst/Tragedy. Recommended.
Collateral Damage: Beyond Birthday torturing Light Yagami, basically. From the writer of Genius is a Curse. Gore, gore, so much gore. Horror and violence.
Fatal Attraction: Beyond Birthday and Light Yagami as Kira are partners in crime. Includes romance between them, but perfectly in character. Crime/Horror. From the writer of Genius is a Curse.
Between the Bones by Narroch: BxLxLight. I can assure you, this is amazing. You will love it. Pure horror and gore. One shot. Recommended.
The Prisoner by nilah-xapiel: BBxLight. “I will murder your conscience, Light… rape your future, and change your life.” Drama, crime, and includes romance. One shot. It looks amazing, very recommended.
B Driven Mad: Beyond Birthday and Light Yagami. I don’t think there’s romance between them, but this seems to be amazing. Light thinks he’s being followed by L’s ghost. Long one shot.
Psycho Love: BBxKira. Horror and gore and everything nasty. One shot.
Vengeance Most Foul: BBxLight on L’s grave. I think it’s horror. One shot.
Dangerous: BBxLight. Smut. One shot.
Beyond Distracting: BBxMisora. Romance/Horror. Based off canon (LABB Murder Cases). Long one shot, from B’s third person POV, and not Misora’s.
the show must go on by deathnoting: BB x A. Talks about Beyond Birthday’s childhood, his time with A, and how A committed suicide. This is brilliant. The writing is beautiful, and it deals with depression, suicide, and child psychological trauma. Beyond Birthday is the main character, of course, and he has some very nice, actual characterization. It’s amazing. 100% recommended. Very, very long one shot.
the haunters by deathnoting: LxB. Victorian gothic AU. Romance/Tragedy. The writing is very beautiful. One shot. “Love is an imperfect science and B is an imperfect scientist.” Fiction T.
Beyond the Ripper: A very short one shot, from B’s POV. I think it’s AU with Beyond Birthday as Jack the Ripper. Horror.
Notes:
There are many amazing LxLight fanfictions which include canon Beyond Birthday as well, most likely through BxL or BxLight. B is not the main character in them, however, because L and Light are. Examples of these fanfictions are Nights, where Beyond Birthday is portrayed amazingly, and very human. He has an actual characterization, a brilliant one. The main plot is LxLight romance, then B appears suddenly and plays a major role in the development of the plot through BxL. B’s own character is explored very exceptionally. Definitely 100% recommended, but it’s a very long work.
Also, Beyond Birthday shows up in Silence, the sequel of Asylum, which is mainly LxLight, but B plays his role through BxLight, and the BxLight parts are brilliant, because B was trapped with Light in the asylum as well. B and Light go on adventures, too. Light goes through psychological trauma because of B.
Since most of the worthy fics recommended here are one shots, it’s not a surprise that B doesn’t have a strong characterization. This doesn’t stop the work itself from being amazing, however, because even B’s homicidal tendencies in these fics are very interesting to witness. It’s fun, and it’s quality.
You have my word that you will like everything you read from this list if you’re into this genre of fiction, of course.
