Goddess of Victory: Nikke is a mobile shooter and gacha game developed by Shift Up and released in 2022, where players recruit characters through randomised summon pulls. The distinctive chime and reveal sound from those pulls quickly became familiar to its large player community and began appearing in fan videos, streams and edits outside the game. Because the sequence captures the tension and reward of a summon in just a few seconds, creators keep reusing it to signal luck, suspense or a big reveal in Nikke content and broader gacha memes.
