if you wondering what happened to the voice talking to tsukasa, it was pretty much a one and done thing that only appeared in the time travel arc

  yes the time travel arc isn't canon to this naruto to boruto harem series...

  If you stumble upon this tale on Amazon, it's taken without the author's consent. Report it.

  anyways that's all

  kobayashi herself is the only person canon in the time travel arc...

  BYE :)

  ((The voice itself also reappears in the canon arcs of this fanfic but brief however in the boruto era it might reappear again but who knows...))
