Here's my analysis of the historical figure of the new Eyecons:
Himiko - shaman queen of Yamataikoku.
Sanzo - Japanese pronunciation of Xuanzang, a Buddhist monk who traveled from China to India
Ishikawa Goemon - a Japanese ninja/outlaw who is the subject of several kabuki plays
Ikkyu - Japanese Buddhist Zen monk and poet
Sakamoto Ryoma - Japanese politician who wanted to modernize Japan during tbe Edo period
King Kamehameha I - Hawaiian king who unified the Hawaiian islands
Grimm? - Can refer to Jacob Grimm, Wilhelm Grimm, or both, German brothers who wrote many popular fairy tales such as Snow White and Rapunzel
Galileo Galilei - Italian astronomer and physicist who supported the heliocentric theory
Charles Darwin - English naturalist who created the Theory of Evolution
Pythagoras - Greek mathematician who discovered the Pythagoream Theorem to find the sides of a right triangle
Florence Nightingale - English nurse who founded modern day nursing and helped those injured in the Crimean war
Christopher Columbus - Italian explorer who accidentally landed in the Americas on a journey for Spain
William Shakespeare - English writer who wrote many famous plays such as Romeo & Juliet and Hamlet
Napoleon Bonaparte - French emperor who was prominent during the French Revolution
Santa Claus - No explanation necessary
Leonardo da Vinci - Italian Renaissance artist, inventor, scientist who made several contributions to the modern day and painted the famous Mona Lisa
Shotaro Ishinomori - Japanese manga writer and the creator Kamen Rider

The fact that there are a couple of eyecons from female historical figures, could be a hint to a female rider...
