Eleanor Forte

Official art, illustrated by 中古アンプ

Eleanor Forte (エレノア フォルテ; formerly known as ENG-F1) was the first American English vocal and the first vocal overall to be released for Synthesizer V. Her first name, "Eleanor", has the meaning of light or bright with a sense of nobility, and her last name, "Forte", has the meaning of strength and references the musical dynamic, forte, which literally translates to loud.

The sealing wax and tied ribbon on the design are inspired by hand-written letters. The thread around her pinky is inspired by the red thread of fate, that indicates that if two people are connected by a red thread they are destined to meet each other. Her dress is inspired by dip-pens.

Despite being a virtual singer, Eleanor has an interest in antiques. She is described to be honest, endeavoring, and to have an unwavering sense of morality.
