Shenanigans in a Magical Forest
This is going to be an actual SPELL CARD DUEL, so you can't just blast her away. You open with a relatively simple DANMAKU pattern to make her see stars.
She counters with UNFAMILIAR GHASTLY SHAPES. Or at least, they're unfamiliar from her. Easy dodging, either way. This early in the game it'll take luck to hit her or waiting for the time to run out. But you still have to dodge.
