S1E95 · Keeping a Promise (2)

As Crow continues his duel against Bolton, he makes a small comeback with his Blackwing Arms Wing. However, Bolton then summons out Crimson Mephist, revealing he was the one who killed Pearson. Pearson had refused to sell his Duel Runner rights for a large sum of cash, so Bolton took matters into his own hands. Crimson Mephist destroys Arms Wing and deals some real damage to Crow. As Crow wonders if he can win, he receives encouragement from the kids he's looked after. Crow's mark glows, which automatically keys in the password to unlocking the sealed compartment in Crow's Blackbird. And Black-Winged Dragon, which was hidden inside the compartment all along, reveals itself. Crow then summons it, and uses its special ability to defeat Bolton, who feels remorse for what he had done, and promises that he will change.
