Witnesses hold secrets within their hearts.
But through the power of the "Magatama" that you will obtain, you can "see" those secrets.
These are known as Psyche-Locks.
In order to resolve your case, you must break these Locks.

If you hit upon a topic a witness really doesn't want to discuss, one or more Psyche-Locks will appear.
A lock symbol will appear on a topic that is under Psyche-Lock.
Until you break these Locks, you won't be able to obtain any more information from this person.

Present the "Magatama" to the witness to start unlocking the Psyche-Locks.
Evidence and profile data will be your weapons in this battle.
Present correct pieces of evidence and/or profiles to break the Locks.
Break all the Locks and new information is yours.
