Natsu and Gray

A black-haired man with a confident expression appears in a dimly lit stone corridor, followed by a pink-haired man winking in a similar setting. The black-haired man is then shown shirtless with a scar on his chest in a cavernous area, while the pink-haired man appears distressed. The black-haired man is next seen glowing with energy, performing a powerful kick. The sequence ends with both men in suits, looking at each other with serious expressions.
