When you ask AIKO about recruiting Candy you will be told that you will have to use her weekly therapy sessions with Synthea to get her on your side.
Dialogue will change depending on whether or not you have previously rescued her from brainwashing.
Requirements:
Complete Synthea's recruitment
After completing these requirements, visit Synthea's office and ask about recruiting Candy. The dialogue changes depending on how you resolved Synthea's recruitment and whether or not you are AIKO's avatar.
Synthea will express her feelings about her sessions with Candy and then will offer to convert Candy to be on your and AIKO's side.
Agree to the plan and you will be welcome to join in and "observe" Candy's next session.
You can also ask Synthea to delay the conversion. Talk to her when you're ready to begin.
You'll eventually receive a request to come to Synthea's office to help with Candy's session.
You can tell her that now isn't a good time. But you have to accept to continue the quest.
Once you arrive, Synthea will present you two options. You can either restore Candy to her original intelligent and ruthless self or you can keep her as a bimbo. In either case, the conversion will nudge her to be loyal to AIKO.
If you choose to keep Candy as a Bimbo, then you will proceed to overload her with enough pleasure that she gladly submits to your and AIKO's will, becoming a willing slut.
Otherwise, you will have to prove your power over her, with a session that shows that true pleasure only comes if she bends the knee to AIKO.
After making your choice and recruiting Candy, you will be interrupted at work by a surprise visit by Synthea and Candy.
Their attire and personalities will depend on your choices. Either Synthea and Candy will both be domme femme fatales, both will be bimbos, or one will be a bimbo led on a leash by the other.
AIKO will then explain Candy and Synthea's new roles and your place in it.
