戦闘員、派遣します！２ (角川スニーカー文庫)

When in doubt, whip it out!
Two months into the Kisaragi occupation, Six can't seem to ditch the nickname the Fly, and Snow is still drowning in debt, thanks to the many loans she's taken out to feed her sword addiction. Meanwhile, the kingdom of Grace's water crisis continues to worsen because Princess Tillis can't bring herself to use the weather machine, which is still locked behind the activation phrase that Six changed to Dick Festival. As punishment, she sends Six to a neighboring country to request magical water-producing crystals...and instead, he causes the country to declare war after showing off his "topknot" party trick. How exactly does that fit into the plan for world domination...?
