Three years ago the aliens invaded Tokyo. Nothing was ever the same again. But after a while, even impending doom starts to feel ordinary. The collaboration between S.E.S. and the Self-Defense Forces is going beautifully. Fujin Type 9s patrol the streets of Tokyo, and the slaughter of the Invaders is at an all-time high.

His delicious cooking almost makes up for the stress of dealing with the constant threat of vigilante exterminators taking him down right in front of her eyes!
