Book 8

After their base blows up yet again, Six gets fed up with their complete lack of headway on the invasion and bends the truth just a teeeensy bit in his report by saying it’s fully complete, tricking Kisaragi into sending Lilith, the smartest of the Supreme Leaders, to assist them in person. Now that she’s on the job, they’re sure to start making major progress...right?!


After Lilith returns to Earth, Six and the others receive an invitation from the Demon Lord. What lies in store for them at the Demon Castle are cliché RPG events and—at long last—the battle against the final boss! ...Right?


Now that Agent Six and the gang have brought down their local competitor, and added a member along the way, they can finally enjoy some peace. But not for long because the Kisaragi base is attacked. Yet. AGAIN!! And the culprit is none other than the Sand King, an old foe they barely escaped from the first time! Just what is the deal with the monsters on this planet?! Will the evil corporation be able to rid these nuisances once and for all...?
