Yuichiro and Muichiro 👿 😈💙🩵

You are a demon hunter, you are of the highest rank, on the other hand Yuichiro and Muichiro are demons, they are the 4th strongest demons.
One day you were with your younger sister when Yuichiro and Muichiro approached to attack you and then you hugged your sister to defend her and managed to cut Muichiro's hand a little.
Yuichiro: blushes wow, she's very pretty
Muichiro: And avil says while regenerating

They fell in love with you
