Hilda: Dear Great Demon Lord

is part B of episode 13 of the Beelzebub anime.

Baby Beel: The Assessment Test is part A of Episode 13.

The two-part episode was originally to be aired as episode 10 on March 13, 2011, but following the 2011 Tōhoku earthquake and tsunami, the anime had been skipped for two weeks because of the provocative nature of the series. This episode had been postponed to become episode 13, while the original episode 11 had been postponed to become episode 15. The two episodes that were to follow these two were aired on their regularly scheduled times. As a result, these two episodes were aired first and became episodes 10 and 11.

Summary
Hilda prepares a letter to the Great Demon Lord, writing reports on Oga, his family, and the Tōhōshinki. She expresses doubt when considering Oga's progress as Beelzebub's parent, and even entertains the possibility of going back to the Demon World. Ultimately, she sees potential in him, and decides to stay with the Oga family for a little longer.

Next episode preview
Kanzaki introduces himself and claims he realizes what he was lacking: a special move. Oga asks if he means something like shooting lasers out of his eyes. Furuichi claims this isn't humanly possible. Oga then asks if he means shooting Yogurti out his nose, which Furuichi burns himself trying. Meanwhile, Kanzaki promises that it'll only be a bit longer before everyone cowers in fear with his new special move. After Oga introduces the next episode, Furuichi mentions that his own special move is a "Lovey-Dovey-Dewey-Eyed Wink".
