Sypnosis
Noir is invited by Emma to come to a social party. The venue is on high alert because a notice was received from the Phantom Thief. Meanwhile, a nobleman challenges Emma to a dance match.

Plot
In the park, Noir gives the Wind Selection to Emma, and after eat it, she test her new skills. After invite Noir to a dancing party, and Noir hesitates, Emma says that if someone kidnaps and does "questionable things", he wouldn't notice and assume the worst about her, going away. At home, Noir discovers that his father couldn't hire a place for their shop because nobody wants to rent for "poor nobles". Changing the subject, Noir asks for a tuxedo for the party, but after seeing the poor state of his father's single toxedo, he decides to buy a new one.

At the party, Emma's parents greet Noir and, like their daughter, acts strange about something Noir doesn't know. After meets Emma, the party host named Bourne announces that a famous duo of trieves known as Phantom wants to steal his most precious jewel (making the Brightness Family nervous), but that the Lahmu Top Adventurers are working security. Noir notice one of them has the same age as him, but twice his level.

In the party, a Viscount named Mike Kentall asks once again to date Emma, but she rejects him. Guessing she was rejeting him because of Noir, he challenges him for a dancing duel, and the winner would win a date with Emma. On his turn, Noir creates a Dancing skill, and wins the duel, but when he and Emma were about to kiss each other, a woman in a costume invades the party and kidnaps Emma, while a man with a mask steals the Mermaid's Tear. Noir decides to ally with the Lahmu Adventurers, and the girl in the team named Leila hesitantly accepts his help.

While the Lahmu Adventurers Leader and the others go after the man, Noir and Leila go after the woman, named Phan, and Emma. While Leila fights against a Firebird summonized by Phan, Noir fights against Phan herself, and they defeat them after Noir bestow the Firebird with weight while Noir hits Phan with the Lightning/Water Fusion. After became friends, the Leader appears, and even with Noir suspecting from him, he traps Noir and Leila, revealing being Tom desguised as the Adventurers Leader.

Tom reveals he wants to marry Emma, making Noir angry, who tries to resist Tom's skill, and while Tom is distracted, Emma wakes up and hits him with her Wind Strike, while Noir knock him down with a punch. They return to the party with the thieves siblings, and both the host and Emma's parents thanks Noir and Leila. In the next day Noir reveals that Bourne rented a place with cheap taxes to Noir as reward, and while the Stardia Family start tidying the place, Emma hugs Noir, promising help them too, making Alice jealous.
