Secret Club Necrozma .

This gift is distributed to players who registered with the Secret Club, to commemorate the registration of 55,555 members with the Pokémon Secret Club!

In order for players to join the Secret Club, players must pre-order Sword & Shield from a participating Japanese retailer.
Players would then receive a code that is required to register with the Secret Club.

The Trainer ID 000132 appears to be a pun based on Secret Club: 1 (hi from hitotsu - first) 3 (mi from mitsu - third) 2 (tsu; Japanese' roman pronunciation of 2) -> Himitsu (means secret)
