Sasaki and Peeps, Vol. 7 (light novel)

The alien behind the recent UFO sightings, whom Sasaki has nicknamed Type Twelve, insists that the others act as her family to teach her the value of human culture. Futarishizuka and Sasaki, however, just want her to go home. It may look like they're only playing house, but the fight for humanity's future rages on. At the same time, a suspicious website announces that the proxy war's next game will be held on an isolated island. Don't be fooled-things may sound like a slice-of-life, but this middle-aged man and his pet java sparrow can't take it easy yet!
