No, while the Jojo reference is appropriate, Sakuya is very much the mother-figure in the Scarlet Mansion. All of these are actually pretty thoughtful selections for the arcana, except for Reimu. She seems more like the Chariot.
Nemeless said: I can understand most of these (Tewi as the Fortune, Aya as the Sun), but why is Yuuka the Lovers?
In tarot readings, the Lovers Arcana initially represented two paths life could lead to, and thus a symbol of standing at a crossroad and needing to make a decision. Today, however, it is portrayed more of a symbol of love and romantic relationships, although it can also be a symbol of finding agreement with an ordinary friend or even two conflicting elements within. That's what the wikia says, so yeah? Two paths... staying in the old Gensokyo or going to the new one? Finding agreement with an ordinary friend... Yeah, got nothing on that.
