These hidden treasures have been sought after by the Negative Syndicate and are capable or enable great power. The relics that are obtained by the Boukenger are placed into a box. Once the relic in question is placed onto the platform, the walls and lid can materialize. In both stages, the Boukengers must wait until a small light at the center turns from red to green. These Precious Boxes can come in any size depending on the Precious and can be depensed from their GouGou Vehicles. Listed here are any monsters the Precious may have turned into or released from within.
