Kogasa Tatara is a whimsical karakasa obake, a traditional Japanese umbrella spirit, from the Touhou Project series. Known for her vibrant personality and playful nature, she often tries to scare humans but usually fails in her attempts, which leads to her being more of a comedic than a threatening presence. Kogasa wields her signature red umbrella and is characterized by her blue hair and mismatched eyes. Her role in the series often involves interactions with other characters as she seeks to perfect her scare tactics and find a place where she belongs.
