Beelzebub - Season 1 Episode 55 I Have Lost My Pompadour / The Great Demon Lord Has Come
Overview: Himekawa introduces himself and tells everyone how he makes his "super cool" pompadour: by hardening it with a hair gel called Pomade. Furuichi ignores him and mentions a man showing up. Himekawa thinks he's referring to the Legendary Warrior, Super Pompadour. Oga asks who that is. After Himekawa introduces the two-part episode, Oga becomes surprised that the Great Demon Lord is showing up, while Himekawa ignores him and worries about his lost pompadour.
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.
