Defenseless

Akira, Selene, and Mizu Soli have been through a lot. So has Lyra and Al Fierce. As they join Fairy Tail and become stronger, they'll have to face their pasts. Lucy Heartfilia joins them through their journey, first as a normal Celestial wizard, then as a Conduit like her female cousins. Go with them in 'Defenseless', the first in the Conduit Series, Eventual AU (no tartaros arc).
