"That is true," Stern said nodding, "As for the mistake... During the battle I failed to think about my allies because I was so into it. Though we had defenses against my ultimate technique: Exploding Dragon, I did not think about their current condition. Granberia tried copying the move and my friends weren't ready for two exploding dragons and they died. For my recklessness, Granberia called off the fight. I forgot to protect my friends and it cost their lives as well as my pride as a warrior. I showed weakness and my friends payed the price. So, I sail alone without a crew, for I do not want to lose another group," Stern explained, revealing he created the Exploding Dragon technique as well as his mistake.
