I don't think boruto has any meaning full death?? Do they??
Previously we had that was kurama but he revived into himawari(or i can say they both are essential one)
Now with the resurrection of nine tails there is no death that is meaning full..
All the deaths that happened in Boruto NNG and TBV
Are -
Momosiki (alive inside of boruto but technically dead)
isshiki (dead)
Delta(died but a cyborg so amado recreated her)
Boruto(died but got revived)
Ryu(dead)
Matsuri(dead)
Bug sinju(dead)
There is no charecter that died to give us some low moments
Boruto feels like the charecter have 1 km thick layer of plot armor..
I am not hating on the story but its true no matter how much of a fan you are
