I'm doing a crossover between primarily Magika Swordsman and Summoner, My Hero Academia and Naruto, in which the emergence of Quirks was used to hide the resurgence of magic [in the form of young girls forming contracts with Divas and subsequently becoming Magika Stigmata due to their contracts with said Divas] and swordsmanship as seen in Magika Swordsman and Summoner, and in the world of said crossover some swordsmen and Magika Stigmata pose as Quirk users, like Magika Swordsman and Summoner, America and Russia fall apart and become third world countries, Germany restores the Hohenzollern-ruled German Empire and subsequently takes over Europe, Japan reclaims Korea, Taiwan, Sakhalin and the Kurils and is in a cold war with the KMT over control of China...etc like in canon Magika Swordsman and Summoner. Only difference is that the Quirk supremacist MLA does not take over Japan through the Hero System and the Hero Commission like in canon MHA, and thus Japan remains a constitutional imperial unitary absolute imperial royal monarchy under the main branch of the post-660 BC reigning royal imperial family of Japan, the supposedly Shinto pantheon-descended, Manchurian/Manchu/Jurchen-Japanese warrior and priestly line turned royal family of thr Imperial House of Great Yamato like in canon Magika Swordsman and Summoner. With no MLA running things from behind the shadows like in canon MHA, there is no Japanese Hero System, instead the Armed Detective System from Hidan no Aria regulates magic and superpower users across Japan in this scenario. No communist putsch in Japan by the MLA after the rise of Quirks and no Hero System means that Midoriya Hiashi, better known as the villian "All for One" over the centuries he has been alive, stealing quirks and building power, is able to evade detection better and after his fight with Shimura Nana, manages to stay low and evade Nana's protoje All Might, although he does fall in love with and eventually marry Nana's niece Inko like in canon MHA. Inko and Hiashi have one boy, Midoriya Izuku from MHA. Izuku replaces Hayashizaki Kazuki from Magika Swordsman and Summoner here, and other UA characters replace their Magika Swordsman and Summoner counterparts, the threat here is not Loki trying to initatate Ragnarok like in canon Magika Swordsman and Summoner, or the MLA trying to keep the status quo like in MHA, the threat is on a group of terrorists from the USA and Russia who want to bring back the Confederate States of America and the Soviet Empire respectively. The terrorists would be crushed but Russia and the USA would fall into deeper darkness along with the rest of the third world when the Ten Tailed Wolf [the wolf Demon Lord that was part of Naruto fanon before 2012] attacked and Ōtsutsuki Kaguya, after eating the chakra fruit after her arrival on Earth, defeated it and [Kaguya] became the so called "Empress of the world", with her son, Ōtsutsuki Hagoromo, becoming the Sage of Six Paths and spreading chakra all over the world, but the developed nations survive both the Ten Tails and the emergence of chakra. By the time the events of Naruto start centuries after the merged Magika Kenshi-BNHA timeline given here, "The Elemental Nations" where the events of Naruto take place in are considered a joke, a place full of mythicism and fakery compared to the advanced nations of Asia, Europe and the Middle East.
