Sakura

A character with pink hair runs across a dark, tunnel-like environment, then collides with a large, glowing white figure, resulting in a bright explosion of light and energy. The figure, which appears to be a massive, translucent entity, is shown reacting to the impact and then turns to face the pink-haired character, who is now seen in a defensive posture. The scene takes place in a dark, enclosed space with a blue and purple color scheme.
