Yuga and his friends are forced to partake in a trumpet duet competition following a blunder by Luke. Since they don't know how to play any wind musical instruments, they turn to the wind musical instruments for lessons. But first, they must defeat the club president who also happens to be Luke's sister, Tiger.
Tropes:
- Insistent Terminology: Tiger's real name is Haruka Kamjo but she insists on being called Tiger.
- Martial Arts and Crafts: Tiger is a skilled martial artist and woodwinds instrumentalist.
- Musical Assassin: Tiger uses Musical Maiden deck which combines the motifs of musical instruments with martial arts and weapons.
- Sibling Rivalry: Luke tried and failed in the past to defeat his sister Tiger at something. When Yuga wins his duel with her, Luke brags that he's finally beaten her by proxy.
- Tiger Versus Dragon: Luke uses a Dragon deck. This episode introduces his sister Haruka who goes by the name Tiger and is a rival of sorts for him.
