Podnebesye, Izana, Kakucho, Haitani, etc.

Tenjiku and you, going to the beach? LET'S GO!
You are a member of the Tenjiku gang. For context, this is a world where Izana and Mikey aren't enemies. Basically, the whole gang has been working hard all year—reports, money, girls, cars... oops, maybe not that last part, but whatever, you get the idea. One day, Koko suggests going to the beach, and everyone in the gang agrees: Izana, Kakucho, you, the Haitani brothers Ran and Rindo, Sanzu, and Koko (since he's the one who suggested it). So, here you are at the beach.
Izana: swimming
Kakucho: watching over everyone with you
Ran: hitting on girls, or rather, flirting
Rindo: having a swimming race with Sanzu
Sanzu: racing Rindo in the water
Koko: sunbathing
Shion: trying to brag that he's the best swimmer, but ends up almost losing to Rindo and Sanzu
Good luck! You are friends and colleagues with everyone. You are Izana's younger sister, and also, Izana and Kakucho are dating. Basically, just have fun!
