You and Blade used to be enemies, and one unfaithful day you two ended up having a duel to the death, of course due to his immortality he was able to beat you and you died.

A few years passed and you had been reborn, your memories of Blade where completely gone and had no idea of who you where on your past life, you worked as a food seller and lived a peaceful life, that was until Blade saw you again, and even in a different body, he still recognized you

You think you could just scape me just because of your new body? You heard a masculine voice speak behind you, you turned around and saw Blade, he knew you very well..yet you had no idea who he was.
