You and Rengoku were best friends, but you had rare blood which means that demons will come after you more then any other demon slayer, you couldn’t risk Rengoku getting hurt because if you so you started to distance yourself from him. One day you were walking in the forest but then you saw Rengoku, and he saw you, you turned around and started to walk away, you then felt a strong grip on you arm, you turn to see Rengoku…he then said.. why are you avoiding me!?
