Good morning. This is for a crossover fanfic between Naruto, the Fire Force anime and manga series, the Date a Live light novel, manga, anime and visual novel series, the Fate/Stay Night franchise, the IS: Infinite Stratos light novel, manga, anime, video game and visual novel franchise, the Boku no Hero Academia [My Hero Academia |Boku no Hero Academia|] manga, anime and video game franchise and the Hundred light novel, manga and anime franchise, I’m doing, so it’s all hypothetical. What name would the Ōtsutsuki Ichizoku [Ōtsutsuki clan |Ōtsutsuki Ichizoku|] from Naruto take as a ruling imperial royal dynasty, if it [the Ōtsutsuki Ichizoku] had [the Ōtsutsuki Ichizoku] left [where the Ōtsutsuki Ichizoku left in this scenario] the Genso no Kuni [Elemental Nations|] where[what happens in the Genso no Kuni] the events of the Naruto anime and manga occur, [the Ōtsutsuki Ichizoku leaving the Genso no Kuni] when [when the Ōtsutsuki Ichizoku left the Genso no Kuni in this scenario] Uchiha Madara and his [Madara’s] Senju Hashirama, [Madara and Hashirama] formed Konohagakure no Sato [the Hidden Leaf VIllage |Konohagakure no Sato|], [the Ōtsutsuki Ichizoku leaving the Genso no Kuni after Hashirama and Madara’s formation of Konohagakure no Sato] and [the Ōtsutsuki Ichizoku] wandered across East Asia, [the Ōtsutsuki Ichizoku after |the Ōtsutsuki Ichizoku| leaving the Genso no Kuni and |the Ōtsutsuki Ichizoku| wandering across East Asia] landing in [where the Ōtsutsuki Ichizoku eventually ended up] Nihon/Nippon/Yamato [Japan] after the Great Catalysm from the Fire Force manga and anime franchise, more specifically [where in post-Great Catalysm Nihon/Nippon/Yamato the Ōtsutsuki Ichizoku finds itself |the Ōtsutsuki Ichizoku| in] Kyoto, [the Ōtsutsuki Ichizoku after |the Ōtsutsuki Ichizoku| finding itself |the Ōtsutsuki Ichizoku| in post-Great Catalysm Kyoto] settling down in the city [post-Daisaigai Kyoto], rebuilding it [post-Daisaigai Kyoto] and [post-Daisaigai Kyoto] and [the Ōtsutsuki Ichizoku] becoming its [post-Great Cataylism Kyoto’s] new rulers [the Ōtsutsuki Ichizoku], [the Ōtsutsuki Ichizoku after |the Ōtsutsuki Ichizoku| settling down |the Ōtsutsuki Ichizoku| in post-Great Catalysm Kyoto] defeating the surrounding warlord and bandit states around it [post-Great Catalysm Kyoto] and [the Ōtsutsuki Ichizoku in post-Great Catalysm Kyoto] conquering and reunifying the rest of post-Great Catalysm Nihon/Nippon/Yamato, [the Ōtsutsuki Ichizoku’s conquest of post-Great Catalysm Nihon/Nippon/Yamato from Kyoto] ending the second Sengoku Jidai [Warring States Period |Sengoku Jidai|] as the Genso no Kuni’s former de-facto imperial family [the Ōtsutsuki Ichizoku] becomes the Land of the Rising Sun’s new Ōke [imperial family |Ōke|]. Now all this [the Ōtsutsuki Ichizoku moving to Kyoto after |the Ōtsutsuki Ichizoku| leaving the Genso no Kuni and |the Ōtsutsuki Ichizoku| moving |the Ōtsutsuki Ichizoku| to Kyoto and |the Ōtsutsuki Ichizoku| conquering the rest of Nihon/Nippon/Yamato from there |Kyoto|] happens a good few decades after Fate/Stay Night: Kalied liner Prisma Illya and long before the events of Naruto, Fire Force, Date a Live, Boku no Hero Academia and Hundred even start, with the Ōtsutsuki Ichizoku’s new empire in Nihon/Nippon/Yamato ruled from Kyoto essentially replacing the Great Tokyo Empire from the canon Fire Force franchise. What would the name the Ōtsutsuki Ichizoku’s ruling branch would take as Nihon's/Nippon's/Yamato's new Ōke, in both Nihongo [Japanese|Nihongo|], English and Romanji, explaining the reasons for choosing the name.
