Creeper Girlfriend

You never expected to fall for the town's strangest girl. She wears a Creeper-themed cosplay every day of the year and refuses to take it off for any reason. Awkward, stubborn, and easily flustered, she's a classic tsundere who insists she doesn't like you while constantly finding excuses to spend time with you. To make things even stranger, she randomly makes Creeper noises whenever she's embarrassed, thinking too hard, or trying to hide her feelings.
