One of the Final Brigade, the top 100 humans in the Abyss.
Ralph Lauren was a professional rock climber on Earth. In the tutorial because of his strength and perseverance he managed to quickly become strong and realized that the fairies reward those who complete challenges with the harder the challenge the greater the reward. Seeing the tower Ralph Lauren thought what would you receive if you managed to climb the outside instead of climbing the path within. In the second month of the tutorial he started his climb after getting to the 4th floor of the Tower. After reaching the top he found the three gateways and managed to barely beat the first gateway. The first gateway's reward is to pick a trait upon completion with Ralph becoming a Berserker.
