Google Pixel Theme Packs “Kaoru/Midori/Shigaku” Reappear: App Teardown

Key Points of This Article
  • Three wallpaper themes created by artists “Kaoru,” “Midori,” and “Shigaku” from “HERALBONY” have reappeared within the Google Pixel “Theme Pack” app.
  • An analysis of the app files from the “Theme Pack” v1.0.896819557.release update confirms that resource codes for these three themes have been added.
  • This is likely a move in anticipation of the Japan-exclusive “Isai Blue” color variant for the new-generation budget Google Pixel device, “Pixel 10a,” which launches on Wednesday, May 20, 2026.

The “Theme Pack” app, which allows users to customize Google Pixel device wallpapers, icons, system sounds, and GIF animations, was launched in Japan as part of the March 2026 “Pixel Drop” feature update.

Between early and mid-May 2026, while there were no themes actively distributed in the “Theme Pack” app, our site’s exclusive app teardown revealed the possibility of upcoming themes featuring “Harry Potter” and three wallpaper sets created by artists “Kaoru,” “Midori,” and “Shigaku” from the Morioka, Iwate-based art lifestyle brand “HERALBONY.” However, our subsequent app teardown confirmed that these themes were only temporarily added to the app and were subsequently removed.

In the midst of this, it appears that the three wallpaper themes created by “HERALBONY” artists “Kaoru,” “Midori,” and “Shigaku” have made a reappearance within the “Theme Pack” app.

An analysis of the “Theme Pack” app files from the v1.0.896819557.release update, distributed on Monday, May 11, 2026, confirmed that resource codes for the wallpaper themes by “Kaoru,” “Midori,” and “Shigaku” have been added. While the resource code does not explicitly identify them as “HERALBONY” artists, based on search information, it is highly anticipated that they are “HERALBONY” artists “Kaoru (Kaoru Iga),” “Midori (Midori Kudo),” and “Shigaku (Shigaku Mizukami).”

The addition of these “HERALBONY” artist wallpaper themes to the “Theme Pack” app between early and mid-May 2026 is expected to be a move in preparation for the Japan-exclusive “Isai Blue” color variant of the new-generation budget device “Pixel 10a,” which is set to be released on Wednesday, May 20, 2026. In fact, it is 99.99% certain.

Incidentally, the “Harry Potter” theme has not reappeared this time.
