I dunno, Gilgamesh to my understanding can probably wipe the floor with Orsted. Rudeus was able to push a severely limited Orsted and even hurt him on several occasions, I mean even Eris with proper counter-techniques was able to dominate him for a few seconds. While Gilgamesh loses mostly to the plot requiring him to, or to ridiculous powerful noble-phantasm like Avalon. Realistic unless you remove some of Orsted curses and limiters he is just getting bodied by Gilgamesh, as for how much of a fight he would put against Gil with his full power I can't say, I've never seen him that strong.
Oof. Gilgamesh with everything? I suppose it depends on which Gilgamesh we're getting.. Like Archer Gilgamesh would be op if utilized correctly and not just chucking them at people, Caster would be scary as he rains down laser beams at everything. If hes still alive non-servant Gilgamesh then that'd be scary with him not being limited. It sounds like fun :D
honestly, I don't really like the original story and even more so the main character, Rudeus, but I love reading the FF, I have high expectations for yours. and about the novel, please, take the readers' comments only as a suggestion, a lot of people go crazy with this subject and a lot of readers think with the wrong head at this time
I fought that this story would be interesting but bunch of ocs and even oc as love interest makes this story not so appealing. If it was in the world with not much fem chars to choose from it would another thing but in a world geared to harem :( nothing personal I just despise ocs as love interest. For me oc is cannon fodder nothing more a char that should be fast discarded nothing more. Of course where could be few exceptions but not in this world and setting
Take your time, the whole idea of gilgamesh being in Mushoku tensei got me EXTREMELY interested so please try your best, and im gonna be selfish and ask you to not drop this book because it has GREAT potential. Not many Mushoku tensei fanfictions since the anime is new and all, so this book should keep me occupied and entertained.
