The “death” for Fai in Outo was always great in the manga because we got to see the reactions of Syaoran and Kurogane to news that Fai had died so early on in the journey. Now of course he didn’t actually die, and readers likely caught on quickly that something wasn’t right (especially considering Syaoran is “killed” in the next chapter, further signaling that they wouldn’t really die).
But what gets to me now during that scene is we now know from (one of the new character guides had the interview I think, that chibiyuuto translated) that CLAMP intended to kill Fai off later on in the story for real. So having him die for fake in Outo near the beginning, would make it hurt more to just kill him for real closer to the end (which would have been their plan at this point when they wrote Outo). Great from a storytelling perspective because it would make fans wonder if he really survived, instilling greater shock when revealing he didn’t live the second time and break their hearts. But man, thankfully CLAMP didn’t actually do it, because Fai deserves to live and it would have been too sad for him to die for reals.
What I love in Tsubasa is that, unlike classic shônen shows where it begins with average protagonists who proceed to progressively gain power in order to make it through whatever is in their way, it starts with a team of the most powerful beings of the multi verse, only that they have to deal with very peculiar issues; lies, half truths, broken relationships, questions on existence, … And the list just keeps on growing until it crumbles from under their feet and they suddenly need to solve things once and for all. As a result, they are not stronger at the end (arguably, they are weaker.), but they are just… So free and lighter and full of love and trust, and I can’t admire Clamp enough for showing how gaining freedom and heart lightness and family love is just as challenging and as fulfilling as gaining the physical power to make your dreams true.
