Ryuzu Myoujin 明神リューズ
He is the founder of the Vanguard Association. After his body died from forcefully summoning the Zodiac Time Beasts, he was "reborn" into a clone body.
His ultimate goal was to summon the 12 Zodiac Time Beasts in order to open the Stride Gate and create a world ruled by logic and reason, which would put an end to the countless atrocities born of humanity's irrational nature, at the cost of sacrificing Planet Cray. Due to his position and machinations he is the main antagonist of the series.
After judgement had been rendered on him, he was reborn into a baby by the power of the Zodiac Time Beasts as a chance to redeem himself and choose his own future.
He is one of the few original users of Gear Chronicle, and was the one who mass produced the clan for public sale.
