Idol Memories: Group Shots

This is from an short anime I saw and finished last night, the story of Idol Memories is about a group of girls living in a futuristic world where live idol music performances and concerts in virtual reality have become an standard, against this backdrop, two rival idol groups, StarRing and Shadow, compete for the coveted tiara, which represents the number one spot in the Idol League.
 

Here are the characters in both groups:

Vivi Lin, the middle-aged girl who is cheerful and honest, got her singing skills from karaoke.

Kokona Hayakawa, the youngest of the group, who decided to become an idol because she admired her great-grandmother, who was a former stage actress.

Sena Hattori, the oldest of StarRing, despite that, she sometimes comes off as an cute airhead.

Miku Kajiwara, the tomboyish leader of Shadow, who is serious and dependable like an adult, but can become childish.

Nanami Hoshi, the busty shy girl who can be easily embarrassed and nervous in front of new people.

Yucho La, the lazy girl of the group, she wanted to be an idol but hates working for that.

For some weird reason, I got a bit aroused to this scene.
