"So how can we revoke Death's Blood agreement? As far as I know, The blood agreement doesn't break until one of them dies...", Fate asked Wish.
"You're absolutely right, one of them has to die...", Wish responded mysteriously.
"I don't get it...", Fate stated.
"BLOOD REBORN, IT IS A TATTOO TECHNIQUE THAT ALLOWS THE USER TO OFFER A PART OF THEIR SOUL AS A SACRIFICE TO PURIFY ONE'S SOUL", Wish replied.
"Blood agreement is a pact connected by two souls and if one of them alters, it is considered as that soul is dead, Then the blood agreement will be revoked", Wish shouted in excitement.
"So all we have to do is to write a book about how to use blood reborn technique and make Death read them", Fate joined with Wish.
"But, Blue...Will surely find this, or she already knew about this technique, she is always ahead of us, what do we do?", Fate asked Wish.
