故事從霧島優返回他曾居住過的島嶼開始，他與多年未見的青梅竹馬水瀬星海重逢。星海曾夢想成為偶像，但因種種現實因素而逐漸失去光彩，幾乎打算放棄自己的夢想。為了讓星海重拾笑容，優提出一個提案：將他親自繪製的插畫化為虛擬偶像，命名為「ヰ世界情緒」（Isekai Joucho），並由星海化身出道。雖然兩人都是首次嘗試虛擬活動，但他們攜手完成首次直播，並以累積10萬訂閱者與舉辦實體演唱會為目標，正式展開成為頂尖虛擬偶像的旅程。

遊戲系統以小說劇情與育成訓練交替進行，在小說劇情中推進故事，隨著育成過程中對星海的唱歌、舞蹈、口才等技能參數進行培養，並安排打工與直播以增加金錢與粉絲數量，決定她的成長方向。這些育成選擇會直接影響劇情分支，最終導致多種不同的結局。需要在訓練、活動與休息之間取得平衡，管理星海的能力與心理狀態，以達成最理想的偶像成果。

主要角色包括水瀬星海，她是一名普通但充滿夢想的高中女生，對成為偶像充滿熱情，雖然曾想放棄，卻依然偷偷練習唱歌與舞蹈；霧島優則是玩家操作的主角，負責引導星海的偶像之路；虛擬偶像「ヰ世界情緒」是星海的虛擬化身，承載著她的夢想與理想；長谷部瑠璃是一名神秘作曲家兼Vocaloid製作人，也是大型VTuber事務所「Tsubaki-iro Studio」的負責人；舞川レイナ與歌方咲分別擔任舞蹈與聲樂教練，協助星海技能成長。此外，遊戲中還有如青葉老師、化步、メチ、春ちゃん、KOKOTH等輔助角色，豐富劇情與日常互動。

作為育成冒險遊戲，其特色在於玩家可以深度參與偶像的成長過程，並體驗從青澀到成熟的心理變化。育成過程中可透過選擇不同訓練方式和活動來提升星海的能力，並影響粉絲數量及故事發展。遊戲同時結合全語音演出，讓每個角色的情感與互動更生動立體。

在市場反應方面，作為由KAMITSUBAKI STUDIO旗下虛擬歌手「ヰ世界情緒」原案打造的遊戲，其話題性與粉絲基礎極高。虛擬偶像星海在音樂與演出方面已有亮眼成績，MV播放量突破500萬，1st及3rd ONE-MAN LIVE演唱會票房全數售罄，為遊戲上市前營造了高度期待感。玩家與粉絲普遍對能在遊戲中直接參與偶像成長、體驗直播與舞台的互動模式表示熱烈關注，預期將在虛擬偶像養成類遊戲中佔有重要地位。

Virtual Ties: Isekai Joucho Dream Symphony is a story-driven training adventure game developed by ENTERGRAM, INC., scheduled for release on Steam on March 18, 2026, and on Nintendo Switch on March 19, 2026. The game blends narrative adventure with idol training mechanics, allowing players to take on the role of Yuu Kirishima, helping his childhood friend Hoshiumi Minase achieve her dream of becoming a virtual idol. The experience combines interactive storytelling with management and training systems, offering multiple branching endings based on player decisions.

The story begins with Yuu returning from Tokyo to the island where he once lived, reuniting with Hoshiumi. Once a girl full of ambition to become an idol, Hoshiumi has recently lost her spark and is on the verge of giving up her dream. Determined to see her smile again, Yuu proposes that she debut as a virtual idol named “Isekai Joucho,” based on an illustration he created. Despite being inexperienced in virtual performances, the pair works together to launch her debut, starting a journey toward 100,000 subscribers and a live concert, marking the beginning of her path to becoming a top virtual idol.

The gameplay alternates between visual novel story segments and training phases. In the novel segments, players follow the story, while the training phases allow them to develop Hoshiumi’s singing, dancing, and speaking abilities. Players also manage her finances and fan base through activities like part-time jobs and live streaming. The choices made in these training segments influence the narrative, creating multiple branching paths and endings. Players must balance training, rest, and fan engagement to maximize her growth and success as an idol.

Key characters include Hoshiumi Minase, an ordinary yet passionate high school girl pursuing her idol dreams; Yuu Kirishima, the protagonist who guides her path; and Isekai Joucho, Hoshiumi’s virtual persona embodying her dream. Supporting characters include Ruri Hasebe, a mysterious composer and head of the VTuber agency Tsubaki-iro Studio; Reina Maikawa, a dedicated dance trainer; and Saki Utakata, a vocal coach. Additional characters, such as Ms. Aoba, Kafu, Mechi, Haru-chan, and KOKOTH, enrich the story with guidance, challenges, and personal interactions.

The game emphasizes deep player involvement in the idol’s growth, letting players experience her emotional development from beginner to performer. Training decisions directly affect Hoshiumi’s abilities, popularity, and story outcome. Full voice acting adds emotional depth and realism to character interactions.

Market anticipation for Virtual Ties is high due to its association with KAMITSUBAKI STUDIO’s virtual singer Isekai Joucho, whose past music videos have exceeded five million views and whose live performances have sold out completely. Fans are eager to experience an interactive journey where they can influence the idol’s growth, witness her live streams, and participate in her virtual career.

Overall, Virtual Ties: Isekai Joucho Dream Symphony combines compelling narrative, interactive character development, and idol training mechanics. It provides players with a rich, immersive experience of pursuing dreams, managing growth, and exploring multiple story outcomes. For fans of virtual idols and story-driven simulation games, this title promises an engaging and unforgettable experience.
