Returning to the dorm one night, Negi, Asuna, Konoka, and Setsuna find the Black Rose Baron eating in their room. They try to capture him, but he escapes out of the window after leaving them with a message about hippopotamuses eating meat even though they’re thought to be herbivores. Asuna gets angry after she notices that the tablecloth the Black Rose Baron was using was actually one of the Chupacabra t-shirts. And so, at the next Chupacabra Research Society meeting, she makes clear to the group that she wants to defeat the Black Rose Baron. When Haruna later catches the group searching for him, Konoka gets rid of her by convincing her that Sammo Hung is giving out autographs in the gymnasium. While all this is going on, Eva is meanwhile meeting with Takamichi about the Black Rose Baron, whom she now knows the true identity of, and his connection to the Star Crystal.
That evening, Negi’s group is back at the dorm, tired after an unsuccessful search. When Fuuka and Fumika run out of snacks to eat, Nodoka offers to go get them some from Haruna’s stash. Negi goes with her and uses his magic to save her when she trips and almost falls. Unbeknownst to him, Haruna and Yue saw everything through peepholes from next door and now know that he’s a mage. The next day, the two of them follow Nodoka and the Chupacabra group as Asuna sets up a trap for the Black Rose Baron using photos of Mt. Fuji and geishas as bait for the foreigner. Someone does indeed appear to take the bait, but it turns out to be just Zazie. Nodoka then goes privately with Negi to the church where she asks him to activate the contract with her. Hiding nearby are Haruna and Yue, who confronted Nodoka about Negi being a mage last night and are behind all this after having learned about the partner stuff from her.
The two girls are so impressed by the transformation that they clap, but this reveals that they’re there. It seems that they made a deal with Nodoka that if they saw her magic, they’d keep Negi’s secret. Seeing that the two girls know everything, Kamo thinks that they should also enact provisional contracts with Negi. Haruna is surprised to learn that it requires a kiss, but she doesn’t think too much of it and goes through with it. When it gets to Yue’s turn however, the group finds that she’s disappeared, and before they can go look for her, Shichimi and Motsu appear. Kamo inadvertently blurts out what happened, causing Shichimi and Motsu to disappear with wicked smiles on their faces. Yue is meanwhile running through the hall of the school thinking that a kiss with Negi is impossible. Suddenly, the Black Rose Baron appears in front of her and shocks her by asking for a kiss.
Given how much Yue and Haruna are in the manga, I would have thought that they would have gotten their contracts earlier – at least before the Narutaki twins. Anyway, there was a point during this episode that I thought Negi might contract with both girls at the same time, but that turned out not to be the case. If I had to guess, I’d say that this would be resolved just like it’s been done for the past however-many-episodes: Negi needs to get Yue to kiss him and form a provisional contract so that he can convince Shichimi and Motsu that she’s his partner. The catch here is that Yue is too embarrassed to kiss him, so Negi and company will have to chase her down and convince her to do it somehow. The wild card seems to be the Black Rose Baron, but it’s still unclear what his objective in all this is. Fittingly, the title of next week’s episode is by Yue.
