ODG is just a man who hates life.
It all started when he was a young lad fresh into summer. One day after a fun and great fishing trip with his dad, his mom asked his dad how his day was. His dad just snapped and savagely beat the entire family before fleeing the country. We're talking about fists and brooms and all sorts of kitchen appliances. ODG took the brunt of the attack.
He never heard from him again, and this has scorned ODG ever since then. All he's searched for since then in life is the simple question of "Why?", and he intends to find that answer where ever he sees fit, even at the expense of all the "prep mans" and "Quanchis" of the world.
When he finds it, he will truly be at peace.
Or something along those lines.
