There's a lot of arcs in this series dealing with the future and past, many different mafia bosses, you have other mafia countries thrown in here, and you have a whimpy boy who is no good and useless for the main character.
For those who read this already know what I am talking about, our main character hero is a boy called Tsuna ( nickname of course ) and is useless and is no good, and can't even confess to the girl that he loves and just skips school all the time as he can never do anything right and he is failing school. Which all ends when he meets up with someone called Reborn who looks like some toddler but is apart of the mafia and is here to train Tsuna into being the best mafia he can be.
In the story Tsuna recruits members for his mafia gang, meets up with many other people who become friends but are also enemies, but as the saying goes, keep your friends close but keep your enemies closer.
Even if they are enemies though they also become very important in the story for Tsuna in his story of becoming the 10th vongola boss.
The beginning is of course slightly boring and slow as it is the introduction trying to get in all the main characters as possible to introduce everyone and explain all the stories and to try to toughen Tsuna up also. But as the story progresses, well that's when all the good awesome action comes in. And also the art gets better if you compare the first chapters to the newest chapters, the art had completely progressed further and you can tell the author got better. But when has anyone started out as a professional artist in the beginning ?
The whole story was very enjoyable even if the story bounced around to different arcs too much it was still very well put. It may have been annoying but it was great. The ending was satisfying too even if nothing too exciting happened it was still very great !
All in all I highly suggest this manga if you are really into the mafia stories with all the action that comes along with it !
