Private companies have been rushing to prove their worth in the Invader containment efforts, and their confirmed kill rates are starting to rival those of the SDF! But there are signs of trouble with the mother ship, and perhaps the Invaders are getting tired of this one-sided slaughter. Meanwhile, Ontan has found an Invader in a human suit and is keeping him at Kadode’s apartment. He’s a bit strange as housemates go, but at least things between Kadode and Mr. Watarase seem to be heating up!

The collaboration between the S.E.S. and the Self-Defense Forces is going beautifully as Hujin Type 9s patrol the streets of Tokyo and the slaughter of the Invaders reaches an all-time high. It’s almost enough to distract the populace from the ominous smoke coming from the mother ship! Meanwhile, Kadode is getting used to having an Invader living in her apartment. His delicious cooking almost makes up for the constant threat of watching him get slaughtered in front of her eyes by vigilante exterminators!

International relations are crumbling as the hotheaded American president demands that the Japanese government share what they know about Invader technology. But the Japanese prime minister has more important things to think about than diplomacy—he wants to make sure his favorite idol is in the bunker with him when the mother ship blows. Meanwhile, the Occult Club is taking a trip to the seashore to meet with someone who claims to have had an extraterrestrial experience! The silly lark ends up revealing something shocking about Oran’s past, but at least the scenery is lovely!

Oba and Makoto forge a special friendship after hanging out on the beach, culminating in the two of them taking a scenic tour through Oran's memories from another timeline!

Too bad it looks like every timeline is the worst timeline...
