BODY: Ever wanted to see yourself reimagined as a sword-wielding hero from Dragon Quest? For eleven days this summer, the streets of Shibuya and Harajuku are your character-creation screen.

Google has launched "Gemini Quest," a promotional collaboration between its generative AI platform Gemini and Square Enix's beloved RPG series Dragon Quest. Running from July 30 to August 9, the campaign sets up shop across four designated areas in Shibuya and Harajuku, where anyone can transform into a fantasy hero — completely free of charge.

The experience leans into Dragon Quest's iconic vocabulary. Instead of typing a dry prompt, participants "cast a spell" (jumon) using Gemini, which then generates an original portrait rendering them in the classic Akira Toriyama-inspired hero aesthetic that has defined the franchise since 1986. GAME Watch's hands-on report walks through the full process of conjuring these AI-generated images on location.

The pairing is a clever bit of cultural marketing. Dragon Quest is arguably Japan's most nationally beloved RPG — a series so ingrained that new mainline releases have historically prompted debates about lost productivity. Attaching Gemini to that legacy gives Google's AI an instant emotional shortcut into the hearts of Japanese consumers, while the physical Shibuya-Harajuku footprint targets exactly the young, trend-savvy crowd Google wants experimenting with its tools.

The insider take

From Tokyo, this reads as textbook Google localization strategy. Global tech brands routinely stumble in Japan by importing generic campaigns, but tying Gemini to Dragon Quest — and framing prompts as jumon — shows real cultural fluency. Shibuya and Harajuku are also deliberate choices: these districts function as Japan's experiential-marketing testing grounds, where a free, photo-friendly AI gimmick is practically engineered to flood social media. Expect the "hero me" portraits to be everywhere on Japanese X and Instagram well before the campaign wraps.
