Beelzebub - Season 1 Episode 13 Baby Beel's Assessment Test / Hilda: Dear Great Demon Lord
Overview: As Ishiyama High holds an assessment test for its studyphobic students, the Great Demon Lord also holds a test for Beelzebub, requiring him to earn points by beating up various things, or run the risk of both he and Oga facing remedial classes in the Demon World. With Beelzebub not showing much hope, Oga decides to try and dump Beelzebub on whoever scores highest on the test. When a rival school interrupts the test, Oga fights them off to allow the other students to keep on the test, earning enough points to avoid remedial lessons, later learning that the smartest student it actually Takayuki. Later, Hilda prepares a letter to the Great Demon Lord, writing reports on Oga, his family and the Tōhōshinki.
Comment
The anime itself doesn't shine in any specific category, and probably some (few) parts/elements are "broken", but all in all it's warm/positive/funny. I didn't like much the first episodes but there weren't any hard reasons to stop watching it so I kept going => I didn't regret that decision - at around the first quarter I started liking it. The last episodes are, in my opinion, superfluous.
