After the events of the last episode, Saito was forced, in his boxers, to read aloud and sign a pledge admitting that he took advantage of Tiffania in the infirmary. However, he refuses to sign it, insisting that it was she who asked him, and leaves. Upon seeing the shack where Professor Colbert kept his books and other materials, he entered and sadly remembered the teacher's wish to someday visit Saito's world. He apparently starts to doze off, but wakes up after hitting his head on the table. His attention then turns to the piles of gifts being left for Guiche and Reynald, and inquires as to their meaning, in which case, Reynald explains that gifts from the ladies are becoming more common after the fight with the Air Dragon Knights from the previous episode. With love seemingly in the air, Saito remembers the fight with Louise and becomes rather depressed. Upon seeing this, Guiche, Malicorne, and Reynald grow determined to cheer him up. A newcomer in the Knights of Ondine, Gimli, comes up with an idea, and they set about to digging a hole to the women's bathhouse, where they use magic to create a small peephole, bringing Saito along to join them. In the bath, Tiffania explains to Louise that it was she who asked Saito to touch her breasts. This leaves Louise a bit upset over her treatment of him, realizing that she didn't even bother to listen, and fears that he may not come back. However, when Tiffania makes the statement that the two are lovers, Louise immediately shoots that notion down. Saito yells for them to stop peeking at her, and his loud voice gathers the attention of Tabitha, who speaks up. The hole is noticed, and their fun is over. They manage to escape, but are found and swiftly punished by the girls. Saito, however, is saved by Tabitha (as a favor for him feeding her dragon earlier in the episode). When Montmorency comes into the dining hall looking for Guiche, Tabitha hides Saito in a rather provocative manner--by pressing her naked body up against him. When word that Guiche has been found, she heads off, but the sound of whispers gains Tabitha's attention, and she soon passes out from fear of ghosts. The dolls appear and start dancing, and Saito is reminded of the party from the first season. Louise shows up, explaining the nature of the dolls' appearance. She has him admit to being with the others who were peeking, but he explains that he was deceived, half expecting her not to believe him. She believes him, though, and they embrace. However, the embrace comes to an abrupt end when Tabitha wakes up for a brief moment, and once again, Louise gets the wrong idea. He ends up in the same position as in the beginning, only this time the pledge is for him never to touch breasts smaller than Louise's (or anyone else, for that matter). In protest, Siesta grabs Saito's hand and rests it on her breast, and in a rage, Louise blows him up.

The episode begins with the Ondine Knights searching for something when a nude girl drops forn the sky onto Malicorne in the same fashion as when Louise lands on Saito in the opening. Louise kicks Saito in the groin and sends him to the ground then proceeds to ask the girl why she is naked. She introduces herself as Irukukwu. She keeps talking about saving her older sister until Guiche asks her about her older sister, who turns out to be Tabitha. She says how Tabitha was taken as a traitor and stripped of her chevaliar title and how Tabitha's mom was arrested. She continues to tell that Tabitha went to save her mom, but was captured in the process. When Irukuwku asks for help, Malicorne and Saito volunteer promptly, but the others doubt her status as Tabitha's younger sister (on the face that Tabitha is pretty flat-chested and that Irukuwku has huge tits). Irukukwu thinks about obtaining proof and rushes out of the door. The Ondine Knights rush out of the door as well, only to find that Irukukwu has vanished. Not long after, Sylphid appears and testifys for Irukukwu. Saito, Guiche, Malicorn and Louise go to Henrietta to ask for permission to go and rescue Tabitha, which she denies on the grounds that as her personal knights, if Tabitha is rescued by the Ondine Knights, as she is considered a criminal, the rescue could be perceived as an act of aggression on Tristan's part. In response, Saito, Guiche and Malicorn resign as knights in order not to trouble Tristan, and Henrietta responds by having them arrested. Louise asks Henrietta what she thinks of Saito as a man not a chevalier, and Henrietta admits that she is not sure if she has fallen for Saito or simply needs someone to lean on. Louise gives up her position as a noble, declaring that she wants to help Tabitha, to repay her for all the times Tabitha has saved her. Henrietta has no choice but to have her arrested as well. After trying, unsuccessfully, to dig their way out of the prison with spoons, the four get rescued by Kirche and Colbert. Irukukwu reveals that she is really Slyphid, which is a rhyme dragon and capable of transforming into a human form.
