Dai and Tetsu

Partnership and loyalty can be a worthy aspect of surviving the end of the world

Dai's life before the Ruin are completley unknown, sometime possibly before or after the Ruin he met Jin and Tetsu where they became very close in partenership. They created a group of both humans and robots including Gido and Toro in search of finding Luna in order to heal the effects of the Ruin. During their journey, they found a mechanical canine who like Jin, was not rusted by the effects of the Ruin. [1]

While greeting this newcomer into their group they are discovered by marauding Bandits. Dai and Tetsu quickly stepped up alongside Jin to battle these Robots until they realized Jin's reputation and moved along instead of fighting. Their next task was to follow the mechanical dog into finding its owner who was trapped under a giant prism. Jin commanded Dai and Tetsu to use their unique equipment to detonate the prison and free the master who turned out to be non other then Casshern.[1]

A man who had been missing from the group named Gido returned with the group of bandits who had passed by as soon as Casshern was freed. Dai stood by as Tetsu questioned if he had betrayed them but Gido assured them that he was trying to save the group by devouring Casshern. The bandits failed to do so and intern, the group pressured Jin to try and devour Casshern in order to save their lives, Dai and Tetsu took no part in this. After Jin calmed the group down by explaining his firm belief in justice and equality, they decided to leave Casshern and the mechanical dog named Friender alone. Dai and Tetsu took note to both Jin and Friender's firm convictions, and even believed that infact may be the reason they don't decay from the Ruin.[1]
