In the original, her name is displayed as 上官妃雪. Since it's a Chinese name, and since all of the guest characters are actually from a Taiwanese game (more info here), we found it best to keep all of their names in Chinese, rather than opting for Japanese readings. The Chinese names also give them a slightly special, "secret-character" feeling.
Chinese reading: Shang Guan Ji Xue
Japanese reading: Joukan Hiyuki

Effort or growth refers to a constant related to the amount of love you have to spend to level. The love spent to level a stat up will be equal the effort constant times that gacha's current stat, disconsidering items.
Aptitude is a simplified representation of effort in the form of a grade from C to S. The lower the effort, the higher the aptitude.
It is currently impossible to meet any of the guest characters in the map. Whether they even have an affection rating is unknown, though the data does have mention of reform options for them, as well as a rival (with the same name as the character herself). Where this rival will be fought against is unknown.
