kal'tsit_(pixiv_fantasia)
Original character made alongside Mon5tr (Pixiv Fantasia) for Pixiv Fantasia T by Lowlight Kirilenko. Later served as the basis for the design of a character of the same name in Arknights.
Notably, her Japanese name is spelled differently from her Arknights counterpart: カルシ (ka-ru-shi) instead of ケルシー (ke-ru-shii)
