The Memory Shard (red) is an item of unknown appearance. It is a special type of equipment that, once obtained, allows Shadow to activate his Chaos Boost Level 2 after filling up his Action Gauge from obtaining Chaos Drives and Light Cores. This grants Shadow the Chaos Lance move, a more powerful version of his Chaos Spear attack.
The Memory Shard (red) becomes available once Shadow and E-123 Omega clear the first boss fight with Mephiles the Dark and return to the present. It can then be bought at the local Shop for 6,000 Rings.
