By good self inserts i do not mean smut or slash novels. I mean good quality "novels" to read. I am looking for self inserts where the plot is the main focus, not the romance. It does not really matter if the fanfiction is on books, anime, etc, just that its good. I would prefer mild isekai themes in that mc wakes up or is transported into the universe of a (anime/manga/movie/etc), but it is not a strict requirement. I am also reading, "Dial" (marvel/ mild ben 10 fanfiction), "the spider" (spiderman fanfiction), "child of heaven" (fairy tail fanfiction), and "A Twelve Step Program to Omnipotence" (marvel fanfiction).
Some that I enjoyed: New Reality (Tales of Symphonia SI) (Will probably never be finished) This Bites! (One Piece SI)
Kenji the Shinobi Craftsman The Doll Gamer Yoru - Gamer Between Dimensions Ephemeral Dream Any Means Necessary All Sir Lucifer Morningstar Fics are great too. Enjoy it.
Man I got all excited about this one until I saw that Pef was the author. Dude has the greatest ideas and puts a lot of effort into his material but personally I can't stand his style of writing. I'm not experienced enough to artfully give constructive advice so I just avoid all his works until I can understand why I dislike it so much.
