Tamamo no mae

Caster is sometimes comic relief, being a goofy, silly, and cheerful young fox girl. Her cheerful personality at times is a brave face she puts on to hide her loneliness. Occasionally, she takes the battle and the situation each week of the game seriously. She doesn't think too much about the consequences of killing.

She becomes infatuated easily and she can't help liking the person she serves. She devoted herself to Hakuno and stood with Hakuno until the very end. To stand by her master until their spirit transcends reincarnation is all she wishes for. She falls in love with Kurono, placing herself in the role of their wife regardless of their gender. She doesn't need the Holy Grail as her wish is to be a devoted wife of Kurono. She expresses that the most important thing over anything else is love. Her affection towards love came from observing humans, stating it was strange that that they were so happy in worshiping her personification of Amaterasu. Seeing so many people fawn over her, she wanted to do the same for someone else. Drawing from her own fate and the actions she took, she believes the intent of person is always important. She will only serve those whose intentions and actions are ultimately good. While stating she would be fine with serving anyone in general, Caster states the person would ultimately need to be good or have good intentions to obtain her service. It doesn't matter if they are male or female, child or adult, or even a saint or sinner, only their intentions matter. That's is one principle she will never betray. Regardless of her notoriety, she wanted to serve someone with content. She likes to cook but not the actual food itself, she enjoys providing meals for her partner and watching them eat it. She also likes to receive presents from her partner but frowns upon cheap gifts.
