The fact that, even after resolving the rest of their issues, Shuro STILL doesn't correct him or anyone else on the island, holds implications that perhaps he's grown to appreciate having this other identity that's separate from his upbringing. Yet another trans allegory of slow transitioning of identity being linked to a different name (used first by your friends).

And then he said, "And then we fought. And you won, of course you did, and now we're talking openly because you're someone I CAN talk to. I always COULD talk to you. I just never DID. Of course you're taking this seriously. And you know I take it all seriously. Why are you like this? Why do I RECOIL every time you speak to me, even when you aren't doing anything wrong? How can a person even be like this?? Why do I sometimes wish that I could be like you?"

AND THEN HE SAID, "Wait. Please. I need you to know I do care about you. I can't tell you that directly because I have been taught my whole life that to love someone is to lessen their burden, to BE less of a burden, shrink yourself, don't have demands, don't have needs, don't eat more than the bare minimum to sustain yourself. I'm working on that now, because of my family, because of her, and because of you, but I still can't bring myself to settle the full weight of my being onto another person. Here is a magic bell that will let you safely become my burden. I will not lose you too."

The magic bell rolls around in Laios' bag and rings constantly because Toshiro didn't think to stuff it with a piece of paper before giving it to the most physically active fighter in the group who does all the runnining aroundening.

The one he JUST brawled for being imperceptive.
