Whatever

Roan was taken aback for a moment and immediately asked Sister Orb. 'Shouldn't the system get rid of anything that affects my soul? Kafan said he could unlock my sealed memories. How come the system didn't get rid of it until now?'

[The system only protects you against harmful things to your soul,] Sister Orb answered. [If someone tried to seal your memories at the moment, the system would definitely consider it as a harmful event and stop it from happening. However, the memories from before you became part of the system are not the system's problem. You could say the system took a picture of how your soul looked when it first took you in and then ensured it stayed that way. Even I didn't know you had a seal in your memories until this point.]

Roan mentally nodded, knowing that the system wasn't exactly thoughtful about such things.
