Light em up

Two anime characters stand side by side in a dark, illuminated arena, then the scene cuts to a fiery environment where a man with a spear confronts a woman with long pink hair, who is shown in close-up with a determined expression, followed by a man with silver hair and green energy around him, and finally a fight sequence where a character with a glowing blue sword attacks another character in a red outfit, all set within a high-tech combat arena.
