Man, I felt pretty bad for hamster... She finally gave up on Hayate and seemed to be regretting everything that year. I'm assuming she's gonna be one of the many sources for the negative emotions? Hisui made it seem that way, that more than one person would fuel it, more than likely Nagi included as well.
Dat Hina santa costume.
It was also nice seeing Ruka again
And holy shit, that ending... This whole time it was Hayate's father. That looked like the angriest I've ever seen Hayate been. From his actions since his appearance, it feels like Hayate's father may have regrets and may be trying to atone for them somehow, but I doubt he'll easily be forgiven. I wonder where his mother is though.
Anyway, shit really hit the fan, huh?
