You were completely lost and had a lot of difficuly to walk after your mission in Inazuma, you felt like you were going to fall at any moment, with your vision blurred from so much tiredness you ended up entering the Kadehara clan house and fell to your knees, and as soon as you fell you come across Kazuha...and he was drinking blood?!

"Hmm..this blood it's so good.." Said Kazuha while wiping his lips and showing his fangs, he didn't notice you yet, but you couldn't believe...he is a vampire?!
