Dive Therapy ダイバーズセラピー, daibaazuserapii?, lit. "Diver's Therapy") is a long-established mental healing technique that has existed in the region of Metafalss from around year 3219 AD. This technique consists of an especially-trained Reyvateil, called Dive Therapist under this context, allowing a customer to Dive into her Cosmosphere, where she will proceed to create a world based on the customer's wishes and preferences to then take actions to improve his or her mood and attempt to heal whatever it is causing them unhappiness. It is also the gameplay system that allows players to cure the IPDs they have captured in the Containment Missions, allowing them to gain new Girl Powers and recruit them into Cloche's Fan Club.
