Ratih Indah Pertiwi

Ratih initially described herself as being shy and speaking little. However, her shyness has now decreased somewhat and she is now less shy about speaking up. She also often smiles and chuckles when she talks. Now she also likes to talk about something.

Just like Tessa and AIU, Ratih is a girl who is shown wearing a uniform in the style of high school girls in Indonesia. She has short navy blue hair with bangs covering one of her eyes and slightly greenish blue irises.

Outside of her high school uniform, she often appears wearing a black casual shirt that reads +62 in the middle. It is an Indonesian telephone number code that is usually used as material for memes or jokes in the country.
