One of his minions raise you while the other kills your girlfriend in front of you.
Or even better, after being killed from the back you share life force with a new sword you found before dying, that sword has a girl inside and after bonding and living together for a long time, it turns out this girl was a second personality created by the original girl in the sword that was made as a self-defense mechanism only because of the trauma of accidentally killing a country when she went on a rampage, so she self-isolated herself for 500 years and she didn't want to ever come back. The only reason the girl in the sword agreed to travel with you is so she could commit suicide when you both reached your goal.
