Don't be fooled by the Romance genre labeling most of her stuff; it's hardly ever the real focus of the story. (The semi-serious ones, anyways.) Most famous for her humorous works, which carry her bizarre, yet lovable sense of humor, she also writes for the Horror and Fantasy genres. And exceeds all expectations. This troper finds practically anything she writes to be godly; especially Kindergarten Warfare and Wolf Me Down.
Someone with an obvious preference for the unusual, she's alarmingly good at both terribly dark and hilariously light genres. There's never a dull moment in her stories, so prepare yourself to be glued to the computer until you're finally finished reading everything that suits your tastes. (And even some that don't.)
A simply spectacular author in a fandom that has been admittedly lackluster as of late. Her style mostly relates to genfics, all of which are interesting enough to become addictive after a while. She's very good at focusing in on characters, which provides a lot of truly thought-provoking insight. I recommend her fics wholeheartedly.
Very talented, but not an author you want to spend time reading all at once. Many of her fics reuse lines verbatim, which can become rather irritating over time.
Synopsis: A tree grown from poisonous soil will always bear poisonous fruit. Ten moments for the each Vongola's cursed lineage.
Comments: A wonderful look into the life of a woman with very scarce canon coverage. The author's headcanon mixes beautifully with actual canon, and the subject of the fic, Ottavo, doesn't come across as a Possession Sue at all, as is usually the fate of these sorts of fics. The author's use of symbolism also makes this fic very much worth your time.
Synopsis: Three and a half years. Since the fights against Shimon. Since the Ninth took up residence in Namimori. Since Tsuna finally got tired of the mafia and disappeared. But now he's back to bring his friends out of their own hells, and maybe save Namimori too.
Comments: This is an M-rated fic, though there won't be any lemons. I will readily say that this is even better than the manga itself. It's over 100,000 words, for those of who you like short ones, but this one is definitely worth it.
Synopsis: After an accident with an experimental bullet, Tsuna finds himself in a dire situation; everyone is infatuated with him! With friends and enemies now desperate to steal his heart, can the Vongola Tenth survive until the effects wear off? If they wear off?
Sypnosis: Mary Sue has invaded Namimori, releasing Sue-beams into the air that has turned all our favorite bishies into complete drones! Only the girls are unaffected by the Sue! Will you be able to help them save the boys and take down the Sue?
Comments: Although you might be wary of the second person point of view, take into consideration that this is a great parody of Mary Sues. With Shout Outs to various tropes and TV Tropes itself, be prepared for a hilarious story with plenty of Lampshade Hanging.
Synopsis: A series of stories that pick up after the Varia arc and turn into an alternate story-line instead of following into the Future Arc. Tsuna gains even more power through very risky means and ends up in big trouble with an unknown enemy. After that's done, he is then put under training under the 9th to become the next boss of Vongola, which means getting enrolled at a mafia school, getting trained to kill with Xanxus as his mentor, of all people, and experiencing everything a Crapsack World like the Mafia has to offer.
Synopsis: In a different world, Tsuna had a different Sun guardian - Kyoko.
Pairings: Tsuna/Kyoko
Comments: An amazing oneshot based around the idea that instead of Ryohei becoming Tsuna's guardian, Kyoko does in his place. Despite the fact that they're alike in personality, how Kyoko sees and handles things is a lot different than Ryohei, and the characterization throughout the story is spot-on. It's not just interesting, it's believable, and makes you really wonder What Could Have Been. Covers the time from the beginning of the manga up through the Varia arc and into the future arc, and leaves you wanting more.
Synopsis: Sawada Tsunayoshi was unassuming. Resourceful. Surprisingly adaptive. A little inept when it came to dealing with romantic affections or unwanted attention. And his hyper-intuition hasn't been wrong yet. Regardless, he didn't need that indication of doom to know that Reborn was the harbinger of utter chaos.
Pairings: None so far, and doubtful if there ever will be.
Status: Ongoing.
Comments: What do you get when you make Tsuna aware of the Mafia from a young age and exposed to things like Doctor Who? A near genius-level hacker and Deadpan Snarker that's apparently a "Mafia-magnet." And still finds time to fail Algebra. Written with the kind of clever, yet random humor that has you grinning silly for hours while you applaud the writer's wittiness, and overloaded with shout outs and quotes that we all know you've heard before. It also holds a plethora of OCs that are just so lovable and unique, you might find yourself cheering for them more often than the actual canon!characters.
Sypnosis: It began on the night when Hibari popped out of his wardrobe. Then from under his bed, his kitchen cabinets, the janitor closet, and trashcans. And as he grew older, slowly but surely, little Tsuna's fear became something akin to love. /Eventual 1827/
Status: Ongoing
Pairings: Hibari/Tsuna, Implied various minor pairings.
Comments: A long and lengthy fic that starts out with hints of WAFF between the titular character, "Boogie Man" Hibari, and an adorable little Tsuna. Gets Darker and Edgier as it progresses, and even the most minor details become Chekhov's Gun. Filled with delightful twists and a well-written plot, this story is simply amazing. Plot Holes are filled, the Alternate Universe the author has created is reminiscent of canon, and the Character Development that every character gets is remarkable. You will be transfixed by this wonderful story.
Synopsis: Reborn had never disagreed with any of the ninth's decisions, but when the Vongola boss sent him to Japan to train Sawada Tamaki, the hitman started to think that the ninth had chosen the wrong twin…
Status: Ongoing
Pairings: None
Comments: There have always been a great many fics that talk about Tsuna having a sibling (most notably a girl), but this one really takes the cake. Tsuna and his twin brother are portrayed as complete foils to one another, and at a first glance, Tamaki is the better candidate, but after a while, Tsuna really shows as the more suitable candidate for the Tenth Vongola. This fic also focuses on how Tsuna gradually becomes friends with Gokudera, Yamamoto, Hana, and many more. Also, a lot of angst, frustration, and tear jerkers on Reborn's part when he realizes that Tsuna's better than Tamaki. The writing is beautiful, and the fight scenes are also well-written.
Synopsis: Everyone has potential. For some, this potential will remain unrealized. For others, this potential may surface. And for Sawada Tsunayoshi, this potential was brought forth much earlier before his teenage years with the baby mafioso Reborn. AU
Status: Ongoing
Pairings: None
Comments: A really different take on a change in events of Tsuna's childhood and the butterfly effect that follows
Synopsis: Primo Fic! What if the Primo gen reincarnates as Tsuna & Guardians.
Status: Dormant
Pairings: None
Comments: Given the canon Time Travel plus character design reuse, why are there not MORE fics like this? I particularly like the fact that Giotto is NOT an uberSue who gets EVERYTHING perfect and right with Super!Intuition and still has to get used to present day and building up his child's body/stamina. Of the Primo Gen, Alaudi and Ugetsu are known to be reincarnated as Hibari and Yamamoto for sure, hints of Knuckles = Ryohei but no actual appearance, and neither Lambo nor Gokudera have shown up ... yet.
Synopsis: A few months after coming back from the future, an unfortunate accident causes Haru to lose her memories, and sends Hayato on a collision course with his past and the memories he's buried and tried -but failed- to forget. Goku Haru; 5986.
Pairings: Main - Gokudera/Haru , Minor - Tsuna/Kyoko, mentioned Ryohei/Hana, implied Ken/Chrome
Comments: Nothing short of amazing story. There is character development in both central characters and the two characters (Gokudera and Haru) unlike some fics truly fall in love with each other. It's believable and sweet. The plot itself is very well-thought out. It's dormant, having not been updating in some time.
Synopsis: Primo Gen Fic! The story of the founding of the Vongola Family and Primo's eventual exile to Japan, as told by G. Slightly unreliable narrator.
Status: Complete
Pairings: Giotto/G, Giotto/OC, D/Elena
Comments: Need more good Primo Fic like this - I don't agree always with the author's portrayal on Mist and Cloud Guardians, but she definitely sets a distinct tone to all the Primo and sets them apart from the Decimo Gen. Do Not Miss the Kewl Reference Notes at the end.
Synopsis: Tsuna, forced to attend one of his tutor's secret dealings, experiences first-hand color gangs, DOLLARS, games and the mystery that is Ikebukuro.
