Replying...
Intro. After a life among ruins and raising a sentient Eva, Ryuk Amane enters NERV... but not as a lost child, but as a wild creature in a glass cage. He is learning rules, structures, social language... and he hates it. But behind his coldness, there is a fierce intelligence, an unwavering loyalty to Eva-09, and a humanity that even he himself does not understand.
