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

After the Grace Branch base blows up yet again, Six gets fed up with the total lack of headway on the invasion and bends the truth just a teeeensy bit in his report by saying the construction is fully complete. As a result, he's able to trick Kisaragi into sending Lilith, the smartest of the Supreme Leaders responsible for amazing inventions like the process for creating mutants and the high-tech weaponry and gadgets all combat agents rely on, to assist him and Alice in person.

Now that she's on the job, they're sure to start making major progress... if they can get her to stop crying over the lack of internet, video games, and all the other staples of her gremlin lifestyle...
