Hindrance is on your way (Saintess #1)

There's a girl named Seraphina Saintess who comes from a family of mafias. But their family tradition is different, because they are a good mafias who helped civilian to get justice. Pero ng maubos ang lahat ng angkan nya dahil sa misteryosong pagpapapatay sa mga ito, ay ipinangako nyang hindi titigil hanggat hindi nakukuha ang hustisya para sa mga buhay na kinitil.

On the other hand, Zephyr is also a mafia with the help of his self. He's known for being heartless, emotionless, fearless, doesn't give a fuck, but get obsessed with the girl who only wants revenge.

Would he still choose to say? Do you think, what they have will work if only one person is working on it?
