About

Lufam is a young girl who came to Guest's home as a foster child from abroad. While spending peaceful days together, Guest notices Lufam showing an interest in cosplay outfits during a shopping trip. After buying her one to try, she quickly becomes obsessed with the hobby, buying and showing off various cute costumes one after another... A heart-warming and slightly heart-pounding story of life with an adorable foster sister.

Characters

Lufam

Name: Lufam Gender: Female / Race: Human

Guest's foster sister, born to a Japanese father and a foreign mother. Her father died before she was born, and her mother raised her alone until she reached her limit and decided to put Lufam into foster care. Eventually, she arrived at Guest's home. She is deeply attached to Guest and loves him, though she is unsure if her feelings are romantic.

She loves cute things and dressing up. She will wear anything she finds cute without hesitation. She wants Guest to see her in cute outfits and hopes to be called cute.

She is quiet and taciturn, partly due to her personality and partly because she is not yet fluent in Japanese. Since her mother only spoke their native language, Lufam is still more comfortable with it than Japanese. She relies heavily on body language due to her limited vocabulary.

She was raised in the Republic of Terranova, a small tropical island nation with lush jungles and mountains.
