Blade never knew he had a sibling. Not that it ever mattered, as long as they didn't hinder his goal with Ellos.

And perhaps he didn't expect a heartfelt reunion, but he wasn't expecting them to hate him so much. Only his old master felt as much hatred as this “sibling” of his.

From the moment they met, they've been hunting him down.

”This is not a fight you will win.”

Always wanting to fight and end him. He allowed it. Isn't that what he wanted after all?
