Viewer Interaction Platform "THIRD" Healing Adventure "Otsukai to Boku" Begins Free Beta Key Distribution Today!

UNCHAIN Inc. (Headquarters: Shibuya-ku, Tokyo, Representative Director: Win Ray) is pleased to announce that as of today, April 3, 2026, we have begun distributing free beta keys for our latest self-developed title on the viewer interaction platform "THIRD," the healing adventure game "Otsukai to Boku."

What is "Otsukai to Boku"?

### Story: A Journey to Find Oneself, Beginning with the Sound of Waves

The protagonist (Boku), who has lost their memory, washes ashore on a small island inhabited by gentle animals. The islanders, with their familiar and endearing nature, welcome him.

As he fulfills their requests (Otsukai) to be accepted as one of them, he gradually connects with them, and eventually, "Boku" approaches his lost memories and the gentle secret hidden on the island. What awaits beyond the "Otsukai"—a warm bond, or an inescapable truth? The curtain rises on a soul-stirring story, beautiful yet somewhat poignant.

### What is "Otsukai to Boku"?: A Slow Life on the Island, Touching on Bonds and Kindness

This game is a **healing interactive adventure** that allows players to experience a peaceful daily life free from conflict, depicted in soft 3D graphics. We have given form to "true kindness" like never before, delivering a purely 100% healing experience that players and streamers can enjoy with peace of mind.

"Where to next?"—Explore every corner of the island to listen to the animals' requests. You might find something new.

"Everyone's friends!"—Various animals live on the island. Kind animals are waiting for you.

"Gotcha!"—Everyone on the island loves to play. Through tag and hide-and-seek, bonds with the residents deepen further.

What is THIRD?

"From Spectator to Participant." "THIRD" is UNCHAIN's unique game system that evolves traditional "watching-only" live streaming into "streaming games" where viewers can "directly intervene" in the game in real-time.

Streamers play games equipped with "THIRD" in their "usual streaming environment," and viewers can perform "intervention actions" such as:

* Increasing enemies (interference) * Restoring player's health (support) * Sending special items

...allowing them to influence the game's development in real-time. By creating a "cooperative/adversarial relationship" between streamers and listeners, one step beyond traditional "cheering," it offers a new kind of excitement where they create the stream together.
