Originally Published In: Submarine No. 4

Summary: On his way to school on a normal rainy day a young boy encounters a strange looking girl. As if her appearance weren't unusual enough, she's stark naked. She climbs on the boy's back where she refuses to leave. Late for school the young man has no choice but to bring this naked girl along to class.

Soon it turns out that the naked girl is actually an alien. Soon the boys guardian spirit (who happens to be Oda Nobunaga, the ruthless Japanese warlord) arrives and wages a war against the girl, who is still attached to the young student. It doesn't take long before Nobunaga's allies are battling against a hoard of aliens who have invaded to side with the naked girl.
