Unfortunately for the Systems, their plans fell a tad short. After all, the one that had looked through Gallo's memories wasn't the actual Compass Carburettor, but a projection of the past.
So, Gallo's luck wasn't significantly reinforced as would have been the case with the original. Had Compass Carburettor fallen prey to Gallo, he would be displaying a sense of pity for him all the time. And whenever he planned to kill Gallo, his sense of pity would be triggered.
And this sense of pity itself would become the luck that protected Gallo from death. Meaning, Compass Carburettor himself would become his enemy, truly turning Gallo invincible.
After that, Gallo's Silly Luck would slowly permeate throughout the Gaider Realm and turn all his plans useless.
