Van and his friends head for the capital city of the Helic Republic and encounter President Louise Theresa Campford.

Van meets Horai, one of the largest living Zoids and learns the meaning of Zoid Eve. Van and Fiona must save the planet Zi from Raven, who has been set loose in a powerfully destructive Zoid.

Van and his intrepid crew cross the ocean in a giant turtle-like Zoid named Kraken, but can they avoid the underwater minefield set by the sea bandits? Illustrations.

Chased by a scorpion-like Zoid, a teenage boy named Van finds himself among ancient ruins. There he witnesses a mysterious machine giving birth to a new type of Zoid -- the organoid Zeke.

Van, a boy growing up on Planet Zi--a world in which the native metal-bodied lifeforms have been turned into fightingmachines by humans--has befriended a newborn Zoid in hopes of someday becoming a pilot like his father, but the relationship between boy and machine is tested when the townis attacked by a monster-sized Zoid and its dark rider.

Seki was a Japanese mathematician in the seventeenth century known for his outstanding achievements, including the elimination theory of systems of algebraic equations, which preceded the works of Étienne Bézout and Leonhard Euler by 80 years. Seki was a contemporary of Isaac Newton and Gottfried Wilhelm Leibniz, although there was apparently no direct interaction between them. The Mathematical Society of Japan and the History of Mathematics Society of Japan hosted the International Conference on History of Mathematics in Commemoration of the 300th Posthumous Anniversary of Seki in 2008. This book is the official record of the conference and includes supplements of collated texts of Seki's original writings with notes in English on these texts. Hikosaburo Komatsu (Professor emeritus, The University of Tokyo), one of the editors, is known for partial differential equations and hyperfunction theory, and for his study on the history of Japanese mathematics. He served as the President of the International Congress of Mathematicians Kyoto 1990.
