She alone bore the sin of her creator for all the sisters created after her. She felt rejected and abandoned by him, convinced that she was broken and unworthy, a failed creation thrown away like trash, and now she was being given a chance. She longed for revenge, to do it her way through all the pain and suffering and somehow win by eliminating everyone else just to spite him and prove herself worthy of his attention. But despite all that she still admired Rozen and loved her Father more than anything and anyone, until she met her last Master. Her sisters didn't understand her and were afraid of her for a reason, she didn't trust humans after getting "betrayed" and despised them in general, she was super lonely and her back is literally cracked and hurts.
Would you be happy and cheerful if you were her?
