Bracket: Fighters IV
The battle began with a loud clash of metal. Both boys wielded swords - one of shadow and one of light. Quite the interesting duo, they were - it reminded me of the sister cross-fight Yu An Xue and Yu An Yan had earlier.
The two backed away from each other at the same time, both with a fearless grin on their faces. Then, wordlessly, they charged back towards one another, meeting once again with their blades. The same process repeated for about a good five exchanges - and quite frankly, it was getting boring.
Finally, the two decided to switch something up. They both used their own respective spells instead to turn the fight into a ranged one. The lightbearer used Light Magic, obviously, and the darkbearer used Shadow Magic. It was pretty funny, since both used a spell of the same archetype - a projectile, explosion-based attack.
