Ep 6. There Aren't Many Customers at the Karaoke Box

As Yozora plans to improve the Neighbors Club's social skills, the group decides to go karaoke in order to develop their ability to sing in front of others. However, the karaoke room they arrive at turns out to be a bit of a letdown as there are very few customers there on that day. Nevertheless, the Neighbors Club is determined to make the most of this opportunity and they begin to sing.

Yozora starts off their karaoke session with an old classic hit which minored in making fun of Kodaka. Kadaka responds by singing a song with a bad voice, which he says suits his personality. They then proceed to undertake many songs, each choosing a piece that they like. Sena, being a good singer, takes the lead in the group and gives the other members some pointers on their singing techniques. She even shows them how to make use of the microphone properly.

Throughout the episode, the group learns more about each other's tastes in music and singing styles. They also get to know each other better in a relaxed and enjoyable setting. They share their thoughts, feelings, and emotions about their past experiences with music. Yozora even reveals that she used to sing in her childhood, but was ridiculed by her mother, and as a result, she's afraid of singing in front of others. As the day goes on, they continue to sing and improve their skills.

However, as the day proceeds, the vibe in the karaoke room starts to become a bit dull and dry, and the group is starting to lose their motivation. Sena, being the determined one of the group, decides to change their approach by singing a song together as a group. She suggests a song that everyone knows well, Happy End, and the group begins to sing it with Sena in the lead vocal. She gives the other members tips on when to come in and harmonize their voices, and they all join in to create a wonderful musical moment together.

The group ends up having a great time, enjoying each other's company and getting better at their singing. The show cuts to a scene where they leave the karaoke room, bidding farewell to the staff, and walking away happily. The Neighbors Club members end their day on a high note, with even Kodaka revealing how much fun he had, and how surprised he is at how good the group was at singing.

Overall, this episode serves to deepen the bonds between the Neighbors Club members and helps them improve their social skills in a relaxed and enjoyable way. Through singing together, they share intimate moments that bring them closer and aid in their self-improvement. The episode ends on a happy note, with the group enthusiastically talking about their experiences and looking forward to their next adventure.
