Inside Ren's soul, the past incarnations were getting a bit rowdy again. Each one of them were telling tales of their epic loves. Most of the incarnations had numerous women in their harem. Others had but a single woman in their whole life. Some even had no one as they believed battle was their only love.
Because fighting each other was getting boring and no new opponent has appeared, the incarnations decided to have a different kind of battle. Since the current incarnation was celebrating his anniversary with his current lover, the incarnations inside his soul started comparing their own tales of love.
As expected most of them fell in love with a woman due to their battle capabilities. Most of their romantic encounters happened during a fight. Others were after they were able to save the girl from certain doom. Some fell in love when they were near death.
