From her archetype showed so far, I'm pretty sure she is a pure maiden and never had a boyfriend. Right?
This is witchcraft though. Wizardry is the study and manipulation of the arcane, while witchcraft is an occult dedication to fey, eldritch, or downright demonic entities. You don't keep your body pure. You whore your soul out.
Shiny Chariot's magic is the definition of pure magic, which is why a dork like Akko can use it, and why no longer being able to use it implies Shiny Chariot is a dried up cum rag.
>supposedly shiny chariot
>can't talk to a single person without spilling the spaghetti
When she became shiny chariot she became her mask, she was as confident and competent as chariot, she was chariot.
But take off the mask and all the self consciousness comes back.
I'm the same way when I wear a suit for some important grown up business I'll behave smoothly but if you catch me in casual mode I'm a mess.
