She works hard and dreams of becoming a famous scientist, giving her the nickname, "The Intelligent Princess". Ami is the best friend of Akikaze Momoko, and excels in both her studies and sports. She is also the present-day incarnation of Winter Snowflake, the princess of snow and intelligence.
Becoming the first target
Ami makes her debut when she walks into the classroom where her twin sister, Yukimura Yuriko, was trying to get Koizumi Hana to talk about her secrets on how to make and care for a perfect garden. Ami was able to get Yuriko to find another person to interview, and winked at Hana, marking the start of their friendly relationship. It was later that day, when Ami was walking home, when she heard a loud crash. She ran to find out what that was, and discovered a man, Koizumi Hana and a green squirrel. Ami grew confused, and the man, whose name was Stone, threw an item called a Shard of Darkness, into Ami's neck, and she fainted, and with a few words, Stone turned poor Ami into a monster called a Hidoi. So now it was up to Hana to save Ami. Hana shouted that Ami didn't deserve this, and that she should and must fulfil her dream. Then Hana suddenly transformed into Cure Tulip, the Pretty Cure of Spring. Cure Tulip had successfully saved Ami, and now the task of finding the other three princesses is in the hands of Cure Tulip.
Becoming Cure Snowflake
Ami had just finished a Student Council Meeting, and went to find her best friend, Akikaze Momoko, but saw that Hana and Chinen Akemi were helping Momoko cook, and Akemi mentioned that she was glad that she, Hana and Momoko were friends. Ami, hurt, ran away into the forest. She then began to cry, then the man who turned Ami into a Hidoi, Stone, appeared and said that her loved her cry of despair. Just then, Ami's sister Yuriko ran into the forest because she wanted to find Ami, but Stone summoned a Shard of Darkness and shot it into Yuriko's neck, and with a few words, Stone turned Yuriko into a Hidoi. Ami was paralysed and felt as if she couldn't move her body. Ami then heard three girls shout something, and in flashes of pink, yellow and red, the girls had arrived. They were the legendary warriors of light, Pretty Cure, Cure Tulip, Cure Flame and Cure Maple. But the Pretty Cure were struggling to defeat the Hidoi. Ami shouted that she loved her sister and that she wanted to protect her always. A green squirrel ran to Ami and started talking! The squirrel, whose name was Bloom, said that she had sensed the power of Winter from Ami, but Ami said that she didn't care a thing about who or what she was, she just wanted to protect all those things and people that she loved. Suddenly, Ami's Season Heart was permanently taken out of her body and changed into a Season Heart Palette. With the help of the Palette, Ami transformed into the Pretty Cure of Winter, Cure Snowflake!

Yukimura (幸村): Yuki (ユキ) is a word that means "snow" and Mura (村) is a word that means "village".
Ami (アミ): The kanji for A (亜) translates to "Asia" or "second", and the kanji for Mi (美) translates to "beauty".
So therefore, Yukimura Ami means either "Asian snow village beauty" or "second snow village beauty". Her surname could be a pun because Ami holds the power of snow and Winter, and her first name could also be a pun because Japan is a part of Asia, and Ami is known as a "beauty" to others.
Cure Snowflake means the snow from Winter when it is falling from the sky, and makes the snowflake with its beautiful style.
