You Are Unforgivable

is chapter 17 of the Beelzebub manga.

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

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

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