Katsura Masakazu takes X by storm with his series of female youkai illustrations

Manga artist Katsura Masakazu has been posting a series of illustrations featuring female youkai and ghosts on his X account for days, and it hasn't gone unnoticed. The latest, uploaded before October 22, shows a futakuchi-onna — the classic Japanese monster with a second mouth on the back of her head — eating a banana with little clothing and a lot of posing.

The piece is titled "Obake Series: Banana Daisuki Futakuchi Onna" and continues a batch that includes the abura-name, a youkai that licks oil and which Katsura drew with her rear as the main focus, along with several portraits of female specters.

The replies on the social network have been quick to follow. Among the comments collected by Japanese outlet Sanyo Shimbun, some highlight "the line from the waist to the rear" as pure wisdom, others admit the drawing makes them think weird things, and another points out that mixing the adorable with the erotic is exactly where the author's personality shines brightest. Another follower quips that the image is "completely unacceptable," and not as a complaint.

A line that doesn't lie

Katsura, born in 1962, debuted in 1981 in Weekly Shonen Jump with Tenkousei wa Hensousei!?, but his name became forever tied to titles like Video Girl Ai, I''s, and ZETMAN. He also handles the character and hero designs for the Tiger & Bunny anime, a job that took him out of the strictly manga circuit.

Katsura's line has always had a recognizable signature: female figures with careful proportions, visible underwear, and a fondness for framing that skirts the limit without fully crossing it. This youkai series doesn't invent anything new, but it condenses those constants into a short format made for scrolling on X.

The author is no stranger to posting standalone illustrations on social media. He does it with some regularity, often bringing back characters from his works or drawing celebrities and VTubers. The difference now is the consistency: several days in a row with the same supernatural theme and the same tone, somewhere between unsettling and festive.

"The line from the waist to the rear is pure wisdom," one follower commented on X.

The series is still ongoing. Katsura hasn't said how many pieces it will include or whether there will be a print collection, and for now the images live only on his profile. What's clear is that female youkai have given him plenty to work with.

What do you think of these Katsura youkai? Do you think he should turn them into an artbook? Tell us in the comments.
