Kaijū no Tokage (The Monster Lizard) launches on April 12

The April issue of Kodansha 's Bessatsu Shōnen Champion magazine revealed on Tuesday that Sōichirō Yamamoto and Kamio Fukuchi will launch their new manga series Kaijū no Tokage (The Monster Lizard) with two full chapters in the next issue on April 12. The magazine teases the story as centering on sisters who discover a mysterious egg.

Yamamoto launched the Teasing Master Takagi-san manga in Gessan mini , the accompanying booklet to Shogakukan 's Gessan ( Monthly Shonen Sunday ) magazine, in 2013. After Yamamoto finished serializing his Fudatsuki no Kyōko-chan manga in Gessan in June 2016, Teasing Master Takagi-san moved to Gessan in July 2016.

The Teasing Master Takagi-san manga inspired a television anime that premiered in January 2018. This anime also adapted Yamamoto's Ashita wa Doyōbi manga as segments within the show. Crunchyroll streamed the anime as it aired in Japan, and Funimation streamed the series with an English dub . The anime will have a second season.

Shogakukan published the Teasing Master Takagi-san manga's 10th compiled book volume on February 12. Yen Press is releasing the manga in English.

Yamamoto is also drawing the ongoing Kunoichi Tsubaki no Mune no Uchi (Inside Tsubaki Kunoichi's Heart) manga, which launched in Gessan in January 2018. Shogakukan published the manga's second volume on February 12. Yamamoto recently launched the Sore Demo Ayumu wa Yosetekuru (Even So, Ayumu Approaches) manga in Weekly Shōnen Magazine on March 6.
