Kiteretsu Daihyakka

Eiichi Kite, known as Kiteretsu, is a young inventor who discovers an encyclopedia left by his ancestor and begins rebuilding the remarkable devices described inside it. His first great creation is Korosuke, a small samurai robot who becomes an excitable member of the household.

With Miyoko, Tongari, and Butagorira, Kiteretsu tests time machines and inventions that make neighborhood problems far larger than they began. Scientific curiosity repeatedly carries the children into other ages, where returning safely depends on repairing whatever their arrival accidentally changed.
