after i end my long research i finally found out that angel and yukino are sisters. ( http://fairytail.wikia.com/wiki/Yukino_Aguria ), She is also the younger sister of Sorano. ( Angel (エンジェル Enjeru) is a powerful Dark Mage and a practitioner of Angel Magic, as well as former Celestial Spirit Mage. A member of the original Oración Seis, one of the most powerful Dark Guilds in the world that once sought the destructive Magic Nirvana,[2] she is among the few remaining members who form the Reborn Oración Seis. Her real name being Sorano (ソラノ Sorano), she is also the elder sister of Yukino Aguria.[3] )
