Gemini (ジェミニ Jemini?) are twin brother and sister spirits who are summoned together. They have the ability to merge together and mimic the appearances and abilities of other characters. Their ability also allows them to read the minds of whoever they mimic. They can only remember two transformations at a time, and forget their oldest transformation upon mimicking a new character. They are introduced as Angel's spirits, but join Lucy after being moved by her love for celestial spirits. The male spirit, Gemi (ジェミー Jemī?), is voiced by Yukiyo Fujii. The female spirit, Mini (ミニー Minī?), is voiced by Kanami Satō.
