Hajime Mitsumiya
specie: Male
age: 62
ht: 5'11
wt: 150 lbs
first appearance: ep 1
Identity: Eccentric inventor, creator of the Neko Robo and paternal grandfather to Nekotaro
Personality: Tough workaholic who keeps pushing Nekotaro and the Neko Robo to their limits. Can appear gruff at times, but genuinely cares for his family.

When I made him, he was supposed to be like Pro. Juuzo Kabuto in the original Mazinger Z series who dies in the first ep... I later reversed the idea and thought of his character as similar to Prof. Sakonji from Voltes V. He has a bad left foot so he always needs his cane to walk.
