Well mine are not transported(except Demonlord) but all of mine are anime based and I think you would enjoy them the links are in my signature.
Hope you like them!

have a look at Terror Infinity - Side Story B or any of the other Terror Infinity fanfictions on this site. The original novel was based around horror movies, but this site's ffs seem to adapt the story to horror anime - or rather any anime.

https://www.fanfiction.net/s/11836721/1/My-life-is-a-game-now : Contains A person who becomes Dante from DMC and goes in the multiverse with the Gamer ability

https://www.fanfiction.net/s/11377916/1/This-Is-My-Life-As-The-Gamer : MC gains the Gamer Ability and travels the multiverse while becoming a Demon Overlord kinda person but kinda a good guy but kills people to gain an ability(Dark Spear) but also has to save other good people and hangs out with them but also attracts attention of that kind from crazy villainous psychopathic chicks who turn out to be sweet irl....... uggghhhhh this fic confuses me..... just read and form your own opinion.

I also love this genre, don't know if you ever read them but there are some chinese novels being translated ,

http://www.novelupdates.com/series/shoujo-grand-summoning/
Complete with 2000 chapters, I read it entire and it was a good read, the MC wakes up in a forest and has a system, he can exchange for skills, descents, weapons etc... anything with points, he gain those points by paying demons cores ( the main world is a world with magic, monsters etc... ) completing missions and etc... he can also go to anime worlds, it's a harem.

Like terror infinity, but not the same, only read the start.

http://www.novelupdates.com/series/holistic-fantasy/
Complete with 2200 chapters, MC wakes up in a forest, he is found by the president of the fairy tail guild, he doesn't has his memories, later on he goes to others anime worlds, like black bullet, overlord, dungeon ni deai, mondaiji-tachi, high school dxd, campione etc... read it entire btw.

There are some others that I know but they are all in chinese and doesn't have any chapter translated ( I read the raws MTL ).

P.S: thanks for the recommendations btw, as a lover of this genre I always welcome more.
