To date, there are seventeen volumes in the True Tenchi Muyo! GXP series of light novels. Volume twelve was written by Masaki Kajishima to augment the second half of the anime. It is unavailable outside of Japan.
Following a recess in the Galactic Federation meetings, Airi and Mikami grab some needed rest. The enemy fleet run by Daluma's Pirate Guild is still at large and posing a major problem for many within the GP's jurisdiction.
Meanwhile, Seina and the gang discuss the merits of a Royal Tree as they tour the Kamidake during its arduous upgrades. Ryoko Balta must contend with the notion that Kamidake's new core is less like a symbol of death of destruction as her instincts would suggest, and more like a cherished pet. Balta's home faction is considering joining the Galactic Union.
Seiryo is scrounging around for trinkets to boost the overall luck of his charge, the Unko.
Seto convinces Seina to chase after Seiryo. Her associate Maya contends that the combination of Seiryo's luck streak and Seina's bad luck should catch a lot of momentum with the press.
Seiryo hears of Seina's instructions to pursue, and stands ready to do battle with him.
