Here, have a list of what our character's Arcana would be in the Persona games. I was bored.
In no particular order:
Minako - Star Arcana. Hopefulness and joy is what Minako embodies. Plus she's based off a spirit from the Chinese zodiac.
Mikhail - Emperor Arcana. Trying too hard to control his surroundings sounds like a thing the djinn would do.
Xenther - Moon Arcana. Moon Arcana = Illusions. Xenther = Doppelganger. Doppelganger = Illusions. I rest my case.
Lieselotte - Hermit Arcana. She always withdrew herself from unfamiliar people before Minako came and did her Star Arcana thing.
Teresha - Lovers Arcana. Full stop.
Lluvia - Devil Arcana. Think about it; Lluvia has only done things for her own reasons ever since she's been introduced. She made it rain because she was painting, for Philemon's sake!
Alan - Hierophant Arcana. Who's building a magical computer? That's right, Alan Bleedin' Radbot. It would be inappropriate not to give him the smart guy Arcana.
Rosabel - Empress Arcana. Woman of authority is woman of authority.
Teague - Strength Arcana. eeeh strong bull man is strong and virtuous and courageous and bleegh
Shen & Sefia - Temperance Arcana. An Arcana about duality and harmony calls for the enlightened twins, methinks.
Walter - Hanged Man Arcana. eeeh self sacrifice man does self sacrifice, man
Zachary - Magician Arcana. The Magician Arcana is about action and initiative, and he's the one who learned magic to help cure and support his sister.
Anyone that I didn't mention was forgotten about or didn't correspond to any Arcana, at least to me.
Feel free to shout at me for not realizing how obvious one character's Arcana is or misinterpreting their personalities.
