The MC Hermann dies, meets God and starts his journey through the fantasy worlds. His aim is to not only travel through anime worlds but see a large amount of different worlds to become stronger and experience new things. I don't own the books and comics this fanfiction is all about and I don't own the new picture as well. I found this on www.pinterest.dk/pin/731905376919081959/ and if the creator wants me to delete it then I will happily oblige. Currently I'm writing another fanfiction called "The Unwilling Sailor" so if you like you could check it out as well First world: My Hero Academia Second world: The Hunger Games

There is a reason everyone calls her the "Iron Lady."  Call her a fashion designer, interior designer, a genius hacker, or even a talented healer. She is all that in a day and a ruthless assassin at night. Did I say she's a triplet? Oh yes!

Follow Adriana Hastings on a mission to acquire the same hard drive that could bring the Rockerfeller family to its knees.  With Aiden Rockerfeller on her tails, how will she shake him off from discovering her or even from getting too close to her heart? The most tormenting factor about the whole situation is that the Rockerfeller family may be responsible for her mother's murder. *** Follow me on: Facebook: https://www.facebook.com/freda.lotsu Tik tok: call_me_mirror Instagram: call_me_mirror Discord: call_me_mirror

THIS BOOK IS DEAD AND WILL NOT BE UPDATED ANY TIME IN THE FUTURE!!!!!! ~~~~~ this is a Fanfiction I'm writing for fun, if you're expecting a complex, over the top, plot twisting story, this is not for you. Again, this is for fun, there will not be any stable releases unless this becomes really popular for some reason or another, thank you~~~~~ Now then for the real synopsis, basically this dude dies, because I'm not original, and meets this god guy whoever the hell he is - gets transported into the Naruto universe and does some well uh... experimenting? Again this is purely for fun, may be dropped for some reason, or it may not. And for that reason I will be putting whatever the hell I want in here, as long as its paced correctly.. I hate stories paced like crap. So harem? sure, but only 2 per universe if I get that far, as long as I know the story then our boy'll go there. Might as well pick up a few girls around the cosmic blob that is space and time - the Naruto Universe pairings are already decided though. System? sure. systems are the only way to grow without being either really lucky or really evil.. or both Another disclaimer this will be a Gary Sue fic so if you dont like horribly OP MC's then this also is not for you If you read this far into here and still want to read then well.. Welcome aboard **********Also this will probably have a LOT of plot holes. and I mean a LOT. so like if I mess something up feel free to inform me. I may or may not fix it depending on how it looks. Thank you*******
