Character's introduction:
Aya Shameimaru is the main protagonist of Shoot the Bullet and Double Spoiler. She is Gensokyo's resident reporter, known for writing "slightly" exaggerated news articles about anything that happens in Gensokyo. She's very strong and is probably stronger than she shows since she sometimes "accidentally wins" battles while only meaning to cover a news story.
Aya first appeared in Bohemian Archive in Japanese Red official book as the reporter of its articles and made her first game debut in Phantasmagoria of Flower View. She is the main protagonist of the spin-off games Shoot the Bullet and Double Spoiler where she fights against various characters while taking pictures of them. She appears again in the mainline games as the Stage 4 Boss in Mountain of Faith and as a playable partner with Reimu Hakurei in Subterranean Animism. She is also a playable character in Scarlet Weather Rhapsody, made an appearance as a background character in Hopeless Masquerade and appeared as a Day 6 Boss in Impossible Spell Card. Hidden Star in Four Seasons reintroduces her as a playable character. Like in Bohemian Archive in Japanese Red, Aya appears as the main character in Alternative Facts in Eastern Utopia, and once again fills the role of reporter for the articles of the book.
