Combatants Will Be Dispatched!, Vol. 8 (manga)

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?!
