Synopsis: Eiri Yuki remembers too much, and wonders if he's going insane. Shuichi helps drive him there.
Comments: Angst with a humorous ending. An examination into the nastiness that is Eiri Yuki's psyche and his gradual revelation that Shuichi is good for him. A companion story to this piece: The Rainy Season
Synopsis: Eiri Comes to terms with his relationship with Tohma.
Warnings: Very NC-17.
Comments: This is the fandom's big important Tohma/Yuki story, and it's a splendid piece of writing. Read it while you can. The author has stormed out of fandom at least three times by my count, though this version hasn't been deleted yet, thankfully.
Comments: You want to read an NC-17 Yuki/Shu? Of course you do. What are you here for, anyway? This is it, the fandom's best Yuki/Shu smutfic. Also recommended is this NC-17 work by the same author: The Nudist
Synopsis: After an argument, Yuki and Tatsuha find themselves locked into a bet to see who can abstain from having sex the longest. But when Shuichi and Ryuichi get in on the act, it becomes a race to the finish line.
Comments: A lot of good-natured fun. Of course it's NC-17.
Pairing(s): Tohma/Eiri is the underlying one. There is also one-sided Ryuichi/Tohma, Sakano/Tohma, and Mika/Tohma. Well, and Tetsuya/Noriko.
Synopsis: Tohma Seguchi has had an eventful life, from the formation of Nittle Grasper to his interactions with Eiri to the later tragedies that ensue.
Comments: The best Nittle Grasper backstory you will find. Period. Noriko isn't pushed into the background, Ryuichi is developed beyond the Genius Ditz stereotype, and Tohma... let's just say that you'll understand all too well how he could have gone from the person at the start of the fic to the person he has become by the canon timeline. Sadly, it's a Dead Fic, but there are more than enough chapters to get a sample of beautiful writing and characterization. Not to mention the extensive Emotional Torque — no one is going to look at Tohma the same way again after reading this fic.
Pairing(s): Tatsuha/Ryuichi, with Shuichi/Yuki on the background
Synopsis: Tatsuha finally gets the chance to meet his idol... but it isn't exactly what he imagined it to be.
Comments: One of the best explorations of what a relationship between side characters Tatsuha and Ryuichi would be like, along with enough Shuichi/Yuki scenes to keep fans of that pairing happy. Hawk Cloud's other fics are well worth reading too.
Synopsis: Ralphiere's collection of her Shuichi/Yuki stories written for the LiveJournal "30 Kisses" challenge, covering a broad range of fluff, humor, angst, and smut.
Comments: Taken separately, each story is a well-written, easily-digestable piece. Together, they make a lovely exploration on all the layers, complexities, and fun moments of Shuichi and Yuki's relationship. (A few kisses are pure smut and pretty much all the others make some reference to boinking going on between two men. You have been warned.)
Pairing(s): Shuichi/Yuki with mentions of Hiro/Ayaka
Synopsis: In the author's own words: "Shuichi is educated in educated in superstardom, hotel mattresses, and the wisdom of pink bunnies."
Comments: Seamlessly intertwines Gravi's music and romance subplots into a whole. Most Gravi fics focus exclusively on romance, but this one also takes an insightful look into the stress of Shuichi's job and fleshes his character beyond the Keet stereotype without overstepping into OOC territory. Plus, there's that blend of drama and fluffiness that makes Gravi so appealing in the first place.
Synopsis: Ayaka's perspective on the events that led her to meet her fiance, his lover, and her second love.
Comments: Does a nice job of addressing the questions surrounding Ayaka's role in strengthening Shuichi and Yuki's relationship and her ultimate decision. Ayaka's hopes and realizations really come through clear in a first-person POV voice eerily reminiscent of what a character like her would sound like.
Gemmifer: It's really good. I didn't finish Graviation because I didn't like it that much and yet I enjoyed this fic a lot.
Synopsis: Yuki can't sleep. It has everything to do with being in a foreign country and suffering from sexual deprivation. It has absolutely nothing to do with Sh things he couldn't care less about. Really.
Comments: Yuki's in-character voice and denial (with a capital D) are hilarious. There are so many quotable lines that you'll have a hard time keeping track of them all.
Pairing: Shuichi/Ryuichi and Shuichi/Eiri. One of them is one-sided, but I'm not going to tell you which.
Synopsis: Bad Luck and Nittle Grasper are on tour together, and Ryuichi finds himself falling head over heels for Shuichi. And in the midst of it all, painful memories are resurfacing. Can Ryu save himself from all the perils of love?
Commentary: A very, very sweet glimpse into the thoughts of Ryuichi. Emotional and amazing.
Pairing: Yuki/Shuichi, (Tatsuha/Ryuichi on the side)
Synopsis: Yuki is irate when his favorite author writes a really crappy book. ChaosEnsues.
Commentary: This is probably one of the most hilarious and best story of Gravitation fanfiction ever made. The characters are spot on in-character (especially Yuki) and it reads like a real short miniseries. This author is relatively famous with the series (she was on the dedication page to the published stand-alone Gravitation novels), and there's a reason why. A real recommend if you want to laugh, cry, or be awed. (The story is currently incomplete, and was last updated in 2006, but is up to nearly 50 chapters.)
Synopsis: Yuki and Taki vies for Shuichi's love and attention. When things get out of hand, they resort to a musical showdown to end things once and for all.
Comments: Yes, you read that right, Taki/Shuichi. The story's a little AU-ish in that Taki, though still a prick, is not Shuichi's rapist but rather Yuki's rival for the singer's hand. Novel-length and humorous.
