Info: Cherii is from the second movie titled ‘Unico Mahou no Shima e’. She takes in Unico and feeds him and wants to be his friend. Her older brother Torubi/Toby shows up and she is frightened by his change. Soon, Torubi’s master Kukuruku/Kuruku appears and turns Cherii’s parents into ‘living dolls.’ She then adventures off with Unico to learn the history of Kukuruku and to save her family.
Cherii’s American name doesn’t sound like you are saying ‘cherry’ but more like ‘Cher’ with an ‘i’ or ‘y’ at the end. Some people translate ‘Cherii’ into ‘Cherry’ because it’s how you would write cherry in katakana.
