I will just say it again! Future Arc!
I was not sure how to structure this but i decided to have it be 2 Segments. The Future Arc and the Final Battle arc. The Future Arc will discuss everything up until the end of Choice and the Final Battle Arc will discuss the inheritance Succession Arc and the Future Final Battle Arc.
The Search for the Guardians was generally a waste of time.
It was full of filler content that wasn't needed and could have been much shorter. The Training episodes were drawn out a bit too much too here. But the Powerups are great. So had they shortened the arc a bit.
By for example leaving out the pointless reunion of Hana and Past Kyoko that led to literally just one short moment as well as the I-Pin and Haru Story as well as the Lambo one (Or combined the 3 stories into at most 2 episodes) and not shown as much stuff as they did about everything i would have liked the arc more.
The Invasion Story was probably my favorite part about this segment.
Simply because Characters that needed it got to do shit and we didn't immediately get Past, Ryohei and Hibari so we actually got to see their future Versions fight properly before getting to see the real heroes adapt their abilities. The Reveal that Shoichi was a good guy all along was done pretty well imo and Spanner is a great character as well.
The Arcobaleno Trials Arc that was done better later. But it is still pure and unadulterated character development but executed kinda poorly. Though enjoyable for what it was at least.
We also were introduced to a few cool characters before this arc in the invasion and training but aside from Gamma nobody is worth Mentioning really except for characters I have already discussed. Of course there are a few key characters that are already introduced by now that I didn't talk about but that's because they are more relevant in the Choice Arc so I will talk about them there.
This arc starts with the Inheritance Succession Arc in all fairness is the Arcobaleno Trials in good.
We also see Primo and his Guardians in the arc and just how much they are like Tsuna and his guardians and how they differ from one another. We get Characterization up the ass for Yamamoto, Gokudera and Tsuna (mostly just those because the other Characters don't change much) and we get awesome new powerups!
So let's go there because everything before was discussed.
The Final Battle.
Simply put Tsunas Guardians are not the strongest and this shows that with brilliant arc shows it. The Vongola have to assemble all the forces they can including the Varia just to somehow survive the fight against Byakurans guys. Which they barely do until Ghost shows up and is explained and he is some sort of major let down but I can deal with that since it's the final battle against Byakuran which as it turns out can only be won by Yuni and gamma sacrificing themselves to revive the other Arcobaleno resulting in the saddest scene in the entire Anime. I liked the fight against Byakuran and his Funeral Wreaths a lot.
