I hate how tsuna just takes on all those legacies and powers but refuses the responsibility that comes with it. I mean seriously the entire manga was denied by that ending. I'm not gonna to claim I know a better ending since that is a matter of opinion BUT what I think is that instead for some color pages with all the characters, I'd rather have some proper closure.
while this may not be the worst ending, it was the one I first thought off on the top of my head. so yeah
Well I'm too dumb to learn any language, all I know is 30% german, 30% english and 40% grunting and pointing, which make up some makeshift way for me to communicate with.
