Forever · Klein Global Birthday Celebration

Centered on a global perspective, this campaign presented a distinctive birthday celebration for Klein. Online activations brought together fans from 34 countries and 200 cities, with tens of thousands participating; fan groups in the United States, Thailand, the Philippines, and Hungary also held local birthday gatherings. More than 34 brands and partners joined the campaign, delivering thousands of gifts to fans.

Offline in Hangzhou, the Gonglian CC Dimension Station hosted the Forever · Klein Global Birthday Celebration — a themed pop‑up birthday party — divided into three content zones: Past·Beyonder, Present·Together, and Future·Infinity, where curated content and interactive mechanics enabled fans to experience the Lord of Mysteries world immersively. Activities, including interactive games, stage performances, author signings, and cosplayer interactions, drove strong fan engagement and social sharing.

At the 2025 Yuewen Global IP Awards, Laurence Larson performed A Stranger, an impression piece recalling Lord of Mysteries Season 1: The Clown. Macau offline highlights — such as MGM Cotai tea & bites and a Meowstery‑themed pop‑up — rounded out a lively program of events.
