Description
Okako is a supporting character in the anime Please Tell Me! Galko-chan. She is a high school girl who belongs to the same class as the series' central trio, and, following the show's convention of giving characters nicknames that reflect their most obvious traits, her name is derived from the Japanese word for the occult. This is appropriate because her defining characteristic is a deep love of the occult in general, and she acts as the class's resident enthusiast for supernatural subjects and horror.

In terms of appearance, Okako has long purple hair that reaches about chest length and brown eyes. Her hair is typically messy and unkempt, and she is shown with a noticeably hunched or stooped posture, which gives her a low-key, slightly disheveled presence among her more polished or expressive classmates. She is a minor but recurring figure in the everyday school setting, blending into the background of classroom conversations until the topic turns toward her specialty.

Her personality is most visible through her interests. She is passionate about the occult and horror, and she occasionally becomes excited together with Galko over horror movies, suggesting that the two share a comfortable friendship built around that common enthusiasm. She is also one of three classmates who form a band together, alongside Metako and Fushigi-chan, indicating that music is another shared activity within her social circle. Her motivations are not given dramatic weight in the series; as a supporting figure in an episodic comedy, she is primarily driven by her enthusiasm for the occult and by enjoying shared hobbies with her friends.

In the story, Okako serves as part of the colorful cast of classmates who populate the school comedy and contribute to its everyday conversations. Her role is to provide another distinct personality among the students, with her occult knowledge and horror-movie passion surfacing whenever a discussion touches on those subjects. She does not undergo significant personal development across the series, as the show's supporting characters generally remain consistent in their traits and relationships rather than receiving major arcs. Her notable abilities are her familiarity with occult topics and horror films, which she brings into group conversations, along with her involvement in a band as part of her social life.
