As the end of one year passes, so does another manga series. Kotaro Mori posted a message via Twitter on December 31st, 2012 announcing the completion of the Gurren Lagann manga in 2013.
The final volume of Gurren Lagann will appear in Japan just as the series is set to re-run over the island nation’s television networks on January 5th, 2013. Mori goes on to add that there will be a reading of the series over the radio on the 15th of each month beginning this January before wishing his followers a Happy New Year’s.
Six volumes of Gurren Lagann were published in North America before Bandai Entertainment ceased publication in early 2012.
