Katekyo Hitman Reborn!: Teacher of Zeroes to Heroes
Hitman Reborn! is about a baby-hitman who becomes a tutor to a 14 year old no-good-boy named Sawada Tsunayoshi or Tsuna for short since he is destined to become the 10th boss of a mafia named the Vongola (clam in Italian). Along the way Tsuna gains friends but for Reborn he thinks of them as Tsuna's subordinates in the mob. They encounter fights with other mob families as well as internal feuds in the family. Reborn is the one responsible for shaping Tsuna to be a powerful man when it comes to fighting using specialized bullets that make Tsuna invincible.
The first 15 episodes are not one of the finest moments in anime history. Starting viewers need to have some patience since the first few episodes focus on character meetings and small developments and this is done using comedy. The comedy presented here is so forced and just completely unfunny. There are a few moments where you will giggle but its not enough to be a complete comedic episode. But once you get to the main story arcs, it gets really good. The story and fighting scenes are amazing. You will be mesmerized by the logic of the story.
The every character has their own quirks and my favorites include Haru Miura,Hibari Kyoya, Gokudera Hayato and I-Pin. There are also a lot of theme songs from the series that will make you hum like crazy. These includes Michishirube (1st ED), Famiglia (15th ED) and Canvas (16th ED). Animation is crisp and clear and I replay some of the greatest episodes I've seen (Ep 182- Silent Storm is a good one).
I recommend that you should watch this. Its 203 episodes long. I know you wouldn't fully enjoy the beginning but once you get to the serious stuff, it will drive you wild and crazy!
