Plot Summary

Opening Theme

"Only you -Kimi to no Kizuna-" by Lc5

Furuichi narrates the story, and Hilda struggles to dress Beelzebub for the cold. Beel simply wears a pink scarf, and Hilda talks in awe about how Beel lets his "thing" hang out. At St. Ishiyama high, Oga and Furuichi arrive to class, and the others talk about Siberia. Then, Aoi enters the room and informs them that they're the only group here. Kazuya and Azusa comes inside the class room and informs them about how school is canceled. Later, Beel opens the door out of curiosity; the snow comes in. Suddenly, a yell is heard from the boy's bathroom. They find Shimokawa whose head in the toilet. Furuichi tries to interpret Shimokawa's message. Then, another voice is heard from the cafeteria. The gang find Ryuji gagged by tempura and wakame. Kazuya suspects the culprit is following the song created by the original Holy Knights after he says the first few verses. Oga is eager to beat them, but Aoi doesn't think it's the Holy Knights due to the volleyball match. Furuichi suspects it's Behemoth. Kanzaki thinks it's Jack Frost, and he and Shiroyama leave to find the culprit.

Then, Kanzaki's scream is heard. The gang finds Kanzaki in the Home Ec room with giant sized yogurt that smells like lavender. Remembering the song, the gang moves to the nurse's office to find Shiroyama naked with the love letter written on his naked body. Furuichi cries about how Aoi is not the one stripped naked with the love letter written on her. Kazuya reminds them of the next verse which involves 5 delinquents beaten up. They looked at the MK5 who ran way, but they got beaten up anyway. Himekawa proposes a plan to catch the suspect by using Furuichi as bait. Furuichi stops fussing after Kazuya tells Aoi that the next verse is about a delinquent blowing a recorder in the girls' locker while wearing a girl's kendo equipment. Furuichi finds out that he can't blow the recorder without taking off his armor. The gang comes out and when one of them ask Himekawa, Himekawa falls out with a big recorder. Furuichi suspects it's Go, yet Shizuka comes out of nowhere. She tells them that Go had disappeared. Then, Furuichi suspects it's Alaindelon who appears behind them out of nowhere.

Back in the classroom, Shizuka explains the next verse which has 75 delinquents split up and fought each other. A scream is heard. Oga and the gang finds Furuichi, Alaindelon, and Kazuya fitting the description in the hallway. While the gang waits in the classroom, Aoi thinks about how she and Oga might be alone together. Suddenly, Beel sees something purple by Aoi. Aoi asks Oga to translate what Beel says since Beel can see demons. Oga resorts to Super Milk Time, but Aoi reminds him of the side effect. Oga throws away the milk bottle, and then, he falls unconscious. Somehow, the room gets really cold, and the girls run to a room. The girls huddle close together. Aoi hugs Beel close to her, and she hears Koma who states his plans about taking out the men and having the girls stripped and huddle naked. Aoi punishes Koma with her bokken.
