You Are Unforgivable

is chapter 17 of the Beelzebub manga.

Summary
Oga is in the way of Nene and Chiaki taking him back to Hilda.

Meanwhile, Hilda is confronting Kunieda elsewhere at Ishiyama High. Kunieda is worried about Oga’s “wife” coming to attack her, thinking she is either aware that she is a member of the Tōhōshinki or aware of Oga forcing Beelzebub onto her. Hilda confirms she is confronting Kunieda and remarks that she might be able to take Beelzebub. Kunieda is nervous and tries to stop Hilda, but she interrupts her and demands a match. Finding words to be futile to Hilda, Kunieda takes out her wooden sword and accepts the match, attempting to dodge Hilda’s attacks and cool her anger. In front of Kunieda's eyes, Hilda disappears, then re-appears from above to lunge at her. Kunieda catches her and defends herself. Hilda remarks that Kunieda`s reactions are first-rate, to which Kunieda disappears and re-appears from behind and launches a sword dance at her. Hilda opens her umbrella to shield herself disappearing. Reappearing behind Kunieda's back, she remarks on how honored she should be for forcing her to draw out her sword from her umbrella. The two clash, causing an large explosion around them. The dust settles, revealing both of them standing on the ground. Hilda, unharmed, observes Kunieda's strength, having just avoided her last assault, but she realizes that Kunieda is uncapable of raising Beelzebub. Kunieda is slightly bruised, puzzled over Hilda pulling a sword out of her umbrella. Suddenly, two of Kunieda's underlings run up to Kunieda, reporting that Nene and Chiaki were beaten by Oga. They take her to the nurse`s office. There, they find Nene and Chiaki unconscious. One of Kunieda's underlings remarks that Nene claimed she and Chiaki went to see Oga to end the ongoing dispute. Kunieda is horrified.

Around Ishiyama High, the word is spreading that Oga beat Nene and Chiaki almost to death and that Oga and Kunieda are about to face each other on the roof. Shiroyama overhears this with shock. At the rooftop, Oga and Kunieda are together again face-to-face, just about to fight each other. Kunieda tells Oga that he is unforgivable.
