wait are there hints or anything towards nameless star's name at all? tell me how you got the name hoshi :D
I don’t know if I would call them hints but there are certain details that I think can help us make an educated guess. A lot of people think her name is Sora mainly due to Yozora asking “Why are you using Sora’s name”, as if he already knows a Sora. I think that’s also definitely a possibility but at the same time I think it’s...too easy? And also I would find it a little strange to have Yozora- which means night sky (-zora=Sora) and another Sora, plus our Sora. But stranger things have happened in kh I guess lol so anyway, that’s one possibility. But I lean towards Hoshi for several reasons: The name/word Hoshi means star-> Hoshi+Yozora=Hoshizora=Starry night sky. This is the sort of wordplay Nomura loves and it’s thematically relevant. What is a night sky without stars but an empty dark void...
Also, although Verum Rex is not Final Fantasy Versus 13, Nomura made direct references to it (the shot for shot recreation of the car scene for example) and Yozora is very obviously the thematic equivalent of Versus 13 Noctis, while Nameless Star is the thematic equivalent of Stella, who was cut entirely from ff15. Yozora’s name is also the Japanese equivalent of the latin Noctis Caelum- Night Sky. Hoshi then, would be the Japanese equivalent of the latin Stella- Star. Another detail: she literally wears a star necklace. Also she is in the form of a star right now- the sort of hidden-in-plain-sight clue/wordplay Nomura absolutely loves. The irony of her being known as “Nameless Star” only to be revealed that her name is literally Star is 100% a Nomura move I can see him doing. She is Yozora’s light. The bright star in the night sky.
And tangentially, to go back to Yozora’s “Why are you using Sora’s name” line, there’s another explanation rather than him personally knowing another Sora, if the Nameless Star’s name isn’t Sora. I’ve written a longer thread about this on Twitter, but to sum it up, he knows he made a vow to save /someone/ (hence the kingstagram with the same words he vows to crystalized Sora) but he doesn’t remember who- only that it’s someone important to him. He is told by someone to “save Sora” and one way or another is convinced “Sora” must be the person he’s been looking for. But he doesn’t know what “Sora” looks like at all, and I don’t think he was expecting “Sora” to be a boy either (because after all, his heart probably still remembers Nameless Star, even if he can’t consciously remember). So at first he’s skeptical that this is the Sora he was looking for. But Sora knows who he is, and fate brought them together, so this Sora must be the person he vowed to save. He thinks our Sora is the person important to him. That’s why after Sora is crystalized, he touches him tenderly and vows to save him- not a gesture one would do for a complete stranger, but someone he thinks he knows and cares about. His memories are getting mixed up, just like Sora’s were in CoM thinking that Namine was a precious person he had promised to protect.
