Nazo no Kanojo X, better known as Mysterious Girlfriend X, is a seinen manga written and illustrated by the artist Riichi Ueshiba, published by the Japanese magazine Afternoon and distributed in tankōbon format by Kōdansha. Started as a one-shot in 2004, the work was then serialized starting in 2006. The series tells the evolution of the love story that develops between Akira Tsubaki, a student at a high school in Tokyo, and his classmate Mikoto Urabe, an introverted and mysterious girl. The two establish an unusual bond, which allows them to communicate their feelings or moods through saliva. Hoods Entertainment’s anime adaptation aired from April 7, 2012, to June 30, 2012 and an OVA was released on August 23, 2012. The first season premiered several years ago, and in this article, we are going to tell you whether you can expect the second season of Mysterious Girlfriend X anytime soon.

  • Article Breakdown:
  • The second season of Mysterious Girlfriend X still hasn’t been confirmed yet.
  • The first season aired ten years ago and while there still is some material to adapt from the original manga series, not counting possible original stories, the second season is still uncertain.
  • Having said all of this, Mysterious Girlfriend X was a pretty intriguing series, and based on all the known facts, a second season is not impossible, although it is unlikely.

Editor’s Note: This post was updated on January 15, 2024; there’s still no news regarding Mysterious Girlfriend X, and the second season at this point is extremely unlikely.

What do we know about Season 2 of Mysterious Girlfriend X?

After Riichi Ueshiba finished the manga Yume Tsukai, he began developing a follow-up work that was initially very similar to this one. So, in the original drafts, he still had an occult theme, and the story was about a girl from an old family with special blood and a boy who fell in love with her. After the publishing editors objected that this structure was not necessary, since girls themselves are mysterious to boys, Ueshiba developed the plot of Nazo no Kanojo X.

A fundamental theme for him was coming of age, as well as the depiction of a non-sexual relationship between teenagers, which is also shown in the fact that Tsubaki and Urabe don’t kiss or even go beyond it, and the “saliva exchange” serves as a substitute. In addition to the unusual plot, Jason Thompson, the author of Manga: The Complete Guide, also highlighted the sometimes surreal drawings of the manga.

The work first appeared as a one-shot in issue 10/2004 (August 2004) of Kodansha’s manga magazine Afternoon. He then developed this into a series that started in issue 5/2006 (March 25, 2006) of the same magazine and ended in issue 11/2014 (September 25, 2014). This series and the one shot – then referred to as Chapter 0 – were combined into 12 tankōbon volumes.

The individual volumes are regularly reissued: the 13th edition of the first volume was published on February 24, 2012. Volume 8 was also released in a limited edition, which included a bonus audio play CD, which also served as a promotion for the subsequently released anime since identical voice actors were used. The limited edition of Volume 9, on the other hand, came with an OVA as a bonus, i.e., a new anime episode.

In issue 2/2012 of Afternoon, released on December 24, 2011, the adaptation of the manga as an anime was announced. The adaptation was produced by Hoods Entertainment and directed by Ayumu Watanabe, who was also working on Uchū Kyōdai at the same time. The character design was made by Ken’ichi Konishi, based on Ueshiba’s template.


The first season aired on Tokyo MX from April 8 to July 1, 2012, after midnight (the previous day of television). Meanwhile, within a week, TV Kanagawa, Sun TV, Chiba TV, TV Saitama, KBS Kyoto, TV Aichi, AT-X, and TV Hokkaidō followed via satellite on BS11 and streamed on Nico Nico Channel. The 13 episodes include selected chapters from the first five volumes. An English-subtitled version ran as a simulcast from April 8 on Crunchyroll under the title Mysterious Girlfriend X for the following countries: USA, Canada, United Kingdom, Ireland, South Africa, Australia, New Zealand, Denmark, Finland, Netherlands, Norway, and Sweden.

Sentai Filmworks licensed the North American video distribution and would go on to stream the anime 31 days after Crunchyroll on The Anime Network and Hulu. The limited edition of volume 9, released on August 23, 2012, was accompanied by a DVD with an OVA episode. What does all of this tell us about a potential second season?

As you can see, the future of the Mysterious Girlfriend X anime is quite uncertain, but not because there’s no interest or lack of material. The series was fairly popular back in the day, but it’s been ten years, and since anime series usually run while there’s a need to promote the written materials, the chances are very slim.

The original manga series ended eight years ago, and no new material has been released, which is why there is no need to promote anything else. Now, this doesn’t completely exclude the possibility of another season, but the chances are slimmer, so we’ll just have to see whether there is enough interest for a continuation to make any proper predictions about the potential continuation of the series. The first season received solid reviews, but we simply don’t know enough to make any predictions on the show’s future.

There was a fan-made petition started in July 2022 calling for the continuation of the Mysterious Girlfriend X anime. The petition reached 5,763 signatures out of the needed 7,500, and since then, there has been no development. The anime will most likely never get a second season and with each passing year, the chances are slimmer.

Theoretically, if Mysterious Girlfriend X Season 2 was to be released, it would arrive late 2024 at best and early 2025 at worst.
