Yamaga Hiroyuki is a co-founder and the current president of Gainax as of writing. He has also directed several anime at Gainax, including Royal Space Force: The Wings of Honnêamise, Mahoromatic and Magical Shopping Arcade Abenobashi.
According to Gainax's now-defunct English-language webpage, he “Bears a certain resemblance to Virgil Tracy, from Thunderbirds. Has a definite thing for neatness. The furniture in his residence is arranged and coordinated so as to mesh with his own movements, and under no circumstances will he let anyone move any of it. He can also bivouac in the snow for a week at a time.”
