1 official ruling from Bandai, last ruled Mar 28, 2024. Straight answers to how this card actually resolves.

I attack an opponent’s Digimon with a Digimon with <Piercing> that has this card in its digivolution cards. My Digimon deletes the opponent’s Digimon and survives. When performing checks with <Piercing>, does this card’s inherited effect grant <Security Attack +1>?
Yes, it does.
