Seto no Hanayome, also known as My Bride is a Mermaid, is an anime television series that follows the life of a teenage boy named Nagasumi Michishio. Nagasumi is on holiday with his parents when he drowns in the ocean and is saved by a mermaid named Sun Seto. As per mermaid law, Nagasumi must marry Sun to avoid being accused of seeing her in her true form. The show revolves around the daily life of Nagasumi and his struggles to keep his relationship with Sun a secret from his friends and family.

In season 1 episode 7, titled Visitor, Nagasumi's school is holding a cultural festival. Nagasumi is excited to participate and is even more excited when he finds out that Sun's family will be attending the festival. Sun is excited to see Nagasumi's school and experience Japanese culture, while Nagasumi is nervous about his friends finding out about his unusual relationship with Sun.

The festival starts off on a good note, with Nagasumi and his friends enjoying various stalls and games. Sun's family arrives and quickly becomes the center of attention. Sun's father, a yakuza boss, is intimidating at first, but he relaxes once he starts enjoying the various festival activities. Sun's mother, on the other hand, is a bit of a diva and happily accepts the adoration of Nagasumi's friends.

As the festival progresses, Nagasumi's friends start to become suspicious of Sun's family. They start to think that they are not a normal family and demand answers from Nagasumi. Nagasumi is forced to come up with convincing lies to keep up the facade, but he is relieved when Sun's family decides to leave early.

However, the festival is far from over. As Nagasumi and his friends are enjoying a haunted house attraction, they run into a mysterious girl who seems to know a lot about Sun's family. She warns Nagasumi that Sun's father is planning something dangerous and that he should be careful.

Nagasumi and his friends are unsure what to make of this warning and decide to investigate. They follow Sun's family and discover that they are involved in a heated dispute with another group of yakuza. Sun's father reveals that he has been challenged to a duel and that if he loses, he will have to hand over his position as boss.

Nagasumi is determined to help Sun's father and comes up with a plan. He convinces the other yakuza boss to call off the duel by offering a truce and a chance at peace. The other yakuza boss accepts the offer, much to the relief of Sun's family.

The episode ends with Nagasumi feeling grateful for the peace he has helped create. He realizes that despite the unusual circumstances of their relationship, he has grown to deeply care for Sun and her family. He looks forward to a future with them, even if it means facing unusual challenges along the way.

Overall, Seto no Hanayome season 1 episode 7 is a heartwarming episode that focuses on the relationship between Nagasumi and Sun. It explores the challenges of keeping secrets and the importance of family. The action-packed ending adds an exciting twist to an already entertaining episode.
