I did one more of those meme, but this time is a bit different because it could be considered "relevant", you know, voices are important for idols.
Yes, Misa's voice is lower than Yukari, unexpected, right? But is not like Yukari voice is super high or that Misa has a very low voice, it just happends to be like that in my mind.
Sachi (even if doesn't look like) is not like Kanata/Moca/Yuyuko and she talks in a normal speed, but she's not very talkative. She only talks when she has something important to say or when something attracts her attention.
Cara's voice is HIGH. like. Kotori level high. Nana can reach that level too if she wants.
Nobuko is like Yohane and has a very versatile voice, she can go from high to low in no time, but she mostly prefer to use a low register to sing.
Hiiragi's voice is also one of the reasons her classmates don't talk to her, she not only intimidates them with her looks and constant death stare (most of the time unintentional), her low voice can be intimidating too, but she's probably Spells Garden's best singer.
Mana's voice reaches unexpected decibels when Nami appears.
