Supernatural Deduction with a Star-Studded Cast
Stepper Retro: Supernatural Deduction Quest is the latest entry in Team Tetrapod’s original mystery series. The game follows Verita Retro, a girl tracking the hidden side of a world filled with supernatural powers.
To enhance the immersion of the document-based deduction system, the developers have recruited top-tier Japanese voice talent:
- Verita Retro: Saho Shirasu
- Vero Retro: Saki Fujita
- Jade Bering: Reina Kawamura
- Caucasus Brian: Tarusuke Shingaki
- Pandoria Redfins: Yumi Hara
Crowdfunding Milestones and Rewards
The domestic crowdfunding campaign on Tumblbug has seen explosive interest, with over 500 “open run” early-bird backers signing up before the official launch.
Key Rewards and Goals:
- Physical Goods: Rewards include a specialized music box, a hardcover “Stepper” series artbook with new content, acrylic keyrings, and layered paper art.
- Stretch Goals: If the campaign reaches its final goal of 240 million KRW, the team plans to implement full Korean dubbing and distribute the next series title for free.
- Global Strategy: Simultaneous funding is also occurring in Japan via CAMPFIRE to target both markets effectively.
