I've seen so many anime and my top 10 are very close in how good they are i would rate all my top 10 anime around 95/100 but Beelzebub is amazing! I rate it 99/100 (Everything has a flaw)
It's just a great mixture of Action and Comedy and gives you a really nice feeling of Adventure.
No.8 on my top ten list (It's not higher cause the others on my top 10 are just closer to my preference)
Also I don't think ep 60 is the lest episode and if it is I'm sure there will be another season later on.
