I hope Jump realizes what kind of peak series they're letting go of. Sequel potential please.
On the contrary, I don't worry about it and for me this ending is great. I'm more rooting for a series or animation.
The series had its ups and downs, but it had a good script and managed to do the main thing - to grow the feeling of family that the series generated.
The scriptwriter got the story right, but I could already feel that it was getting a little tiring. It's better to end on a high note than to have a bad sequel.
