So he has seen the roster. This will make things a bit easier, then. "It does that for some people, though I could not for the life of me tell you why." And he tends not to inquire; there is equal chance of it being a simple mistake in a complex algorithm or someone's deep trauma, and he is not about to voluntarily navigate that minefield without cause.

He pulls up the roster and scrolls all the way to the bottom, gesturing to Devero's picture and the long string of letters and numbers beside it. "For example, his name is Devero. From what I have seen, he is the friendly sort." He then scrolls back up to Senku's picture and gestures to it. "And this is Senku. Yes, that age is accurate, and he will likely tell you the story if you ask." He pauses for a moment - his name and photo are not far below Senku's. "Ah- apologies. I seem to have forgotten to introduce myself. I am Siebren de Kuiper." He offers a handshake.
