Kozue Tanabe is a female character in the manga Squid Girl, a mysterious woman who briefly appears by the seaside to encourage Squid Girl when her invasion efforts stall.
Kozue Tanabe first appears in Episode 40, "Won't You Worry?", collected in volume 3 of the manga.
She approaches Squid Girl and Eiko Aizawa on the beach, speaking gently to the discouraged Squid Girl before quietly leaving.
She wears a strange hat that resembles the head of an octopus.
Her calm manner and cryptic words give her an unusual, almost supernatural presence.
In the anime, her voice is performed by Akemi Kanda.
She appears in episode 12 of both the first and second anime seasons.
Her original appearance is very brief, but it leaves a strong impression.
She serves as a mysterious figure who comforts Squid Girl at a moment of self-doubt.
In the original manga, she appears in only one main chapter and one bonus comic.
Despite that limited role, she became memorable because of how little is explained about her.
After that, she does not appear again in the main story for a long time.
She later returns in the newly drawn bonus story Squid Girl! and Kozue Tanabe, included in volume 22, the final volume.
Kozue Tanabe is widely discussed because the story strongly hints that she may not be an ordinary human.
Her way of speaking suggests that she is some kind of being from the sea.
Fans have often speculated that her true identity might be an octopus girl.
However, the manga never directly confirms this.
Several details helped fuel that theory.
Her name reading emphasizes syllables that resemble the word for octopus, the written form of her given name evokes the image of an octopus, and her red hat resembles an octopus's rounded body.
Another reason for the speculation comes from a comment by the author in the afterword of volume 4.
The author mentioned that there was no character on the same level as Squid Girl and suggested it might be interesting to introduce one in the future.
Even so, Kozue's true nature remains officially unrevealed.
The series reaches its ending without giving a definite answer.
Although her identity is never fully explained, the opening bonus comic in volume 22 includes expressions that seem to hint at the answer.
This makes her final appearance especially interesting for longtime readers.
Her portrayal in volume 22 is also somewhat different from her earlier appearances.
She still acts seriously, but the tone is more comedic than the mysterious image she had in volume 3 and in the anime finales.
Because she had long been rumored to be a character or a piece of foreshadowing meant for the ending, this later use of her can feel like a playful self-parody by the author.
That contrast only adds to her charm.
