A magazine-only oneshot from Garo 1969-08.
This is the second half of the story. The travelers set up a campsite on the island and treat it all as a big picnic. The Japanese navy arrives and orders them to go back home and they refuse. By accident, the fat rich kid stumbles on a rock on a hilltop, triggering an avalanche that crashes down on the destroyer. This starts a war with the navy using their big guns, and the travelers using slingshots, swords and a spear. One woman, the one with a spear that loves Edo-period dramas, starts out thinking that if she’s going to die here that she’d rather do it by her own hand. However, she pulls her head out of the noose and decides that she’d rather die in a hail of bullets. She gets shot, and dies thinking that neither choice was really all that preferable. A small boat arrives with two men and a lot of film equipment. The travelers think they’ve been saved, but rather than helping out, the two newbies start filming the battle, and asking people to do a better job of looking good when they die. The prophet that started all of this pulls out his katana to show how a real samurai fights, but he turns out to be incompetent. The prophet tells his assistant to fight for him, and the boy lights the fuse to a pile of gunpowder kegs and bombs. The island blows up, killing everyone but the itinerant priest. The priest turns away, muttering a prayer to the souls of the dead, and he leaves.
There are a couple sight gags here, including cameo appearances by Tezuka’s “pig character”, and Fujio Akatsuka’s Nyarome cat.
