supposedly all this is just a way to get Tsuna trained or get used to stuff before the story gets serious. and i don't think you can call them fillers if this actually happened in the manga.
It’s a snowy day in Namimori, and Tsuna is reluctantly led to school by Reborn along with Lambo and I-Pin, who are in high spirits. To his surprise, his friends are there, willing to help pitch in and take care of the younger children. But
Kyoya: I figured I'd pound anyone who happened to be here.
Tsuna: Why don't the cops arrest this guy?
Me: LOL I know right? But the cops would be too afraid to that cuz he wud Bite them to death.
"Deathperation..." Man, I really can't stand that name, it's like they have a bad lisp or something. I preferred the old translation of "Dying Will," it sounded so much more cool.
