kokkoro (princess connect!)
A character from Princess Connect! Re:Dive (she did not appear in the original Princess Connect!). She also appears in Granblue Fantasy as a special event character.
She is short and slender elf with shoulder length silver hair, pink eyes and pointy ears. She usually wears a green and white sleeveless dress, light green detached sleeves, and a hair flower.
Sometimes her name is spelled "Coccoro" by fans, but it's romanized as "Kokkoro" in the official English translation of the Granblue Fantasy crossover event.
Her name in the real world before the events of Re:Dive was Kokoro Natsume (棗こころ).
