When Claudia understood the nature of her husband's research, and that herself and Maria were the cause of it, she despaired. When she knew that he was near the final stage of his research, she wondered if she might not take both the prototype and Maria and escape and proposed this to Nikolai. However, to activate the prototype for Maria, Maria's brain must be synchronized with the nervous system and brain wave patterns to be able to operate it. Claudia wished that her own brain be used, and amidst great anguish, Doctor Nikolai resolved to do this. Claudia was secretly fused with the prototype Seibzehn, and an accident was caused on purpose, creating the circumstances of her death. After this, when Seibzehn was completed, using his great skill Doctor Nikolai hid the M Plan inside Seibzehn's base program, entrusting it to take Maria and escape. He secretly contacted his Grandfather Balthasar, entrusting him to be Maria's guardian after the escape. Because Claudia, as her mother, had wanted to protect Maria, she desired fusion with Seibzehn. Maria continues to think her mother died in an accident, but from time to time she can feel something inside Seibzehn different from her father. Perhaps it is her mother's will.
