Ask for a Japanese animation

Lz said the name is Iaria, Iaria is the most introverted little guy. She is also the youngest of 12 sisters. She looks extremely cute and wears the costume of a French lady. Walking with an exquisite umbrella every day makes people feel as cute as a real doll. Iaria speaks slowly and has a lovely voice, which often makes people unable to hear what she wants to say, but in the face of such a lovely little guy, no matter who she is, she will give in ... She likes sweet candy, colorful things, cute things and cool feelings. Iaria gives the impression that she is a pure little girl, pure as a clear spring, and I can't help but want to hug her.

There are several sisters: unfortunately, Hua Sui, Snow White, Ju Hui, Lingling, Fish, Wei and Xiao.
