《甜星姊妹》是以「陪伴雙胞胎兔女郎姊妹成長、共同追逐夢想」為核心主題的養成系戀愛冒險遊戲。整體氛圍溫柔浪漫，結合同居生活、舞者養成與情感深化，讓玩家在日常互動與劇情推進中，逐步走近兩位性格迥異的姊妹，陪伴她們在舞台上發光，也在生活中建立專屬於三人的情感連結。遊戲由人氣插畫家柊林檎與曾負責《戰國†戀姬》系列的劇本家K.バッジョ合作打造，風格明亮細膩，極具戀愛遊戲玩家的期待值。

故事從城市角落的一間復古酒吧「BACCHUS」開始。主角因祖父過世而繼承這家具有歷史感的店鋪，但生意蕭條，已無往日繁盛。為了振興酒吧，他決定向青梅竹馬的雙胞胎姊妹──安雅與莎雅──尋求協助。這對混血姊妹以鋼管舞與舞台表演聞名，是當地的話題明星。她們並非天賦異稟，而是靠著不斷練習、堅持努力而站上舞台。隨著主角接手酒吧，姊妹倆搬進他的生活空間，三人開始同居並朝著在大型舞台比賽奪冠的共同目標前進。故事在酒吧營運、舞台訓練與日常生活的交織中展開，主角與兩位姊妹的情感也從青梅竹馬，逐漸發展為更加深刻的羈絆。

安雅是雙胞胎中的姊姊，擁有瑞典母親與日本父親的血統，外貌柔和，氣質沉穩。她給人溫柔成熟、富有包容力的印象，總是默默照顧妹妹與主角，是典型的「好姐姐」角色。雖然擁有理性與分析型思維，是舞台上的理論派，但生活中卻有廚藝極差的反差萌。從小便喜歡主角的她，因害羞而難以直接表達感情，只能透過細微的行動展現關心。她在面對妹妹的熱情撒嬌時常會害羞得不知所措，而在與主角獨處時也常出現細膩溫柔的互動，是能給玩家安心感的角色代表。

妹妹莎雅則完全相反，是陽光、自由、外向的活力來源。她同樣是混血，充滿朝氣、喜歡新鮮事物，走到哪裡都是人群焦點。她愛撒嬌，經常直接對主角表達喜歡，也喜歡主動接觸姊姊，是個不掩飾自己情感、坦率又黏人的少女。雖然她外表無憂無慮，但其實意志堅強，為舞台表演付出的努力絲毫不輸給姊姊。只是當遭到責備時，她會立刻失落，需要主角與安雅的溫柔陪伴。莎雅的活力與坦率為故事增添大量甜蜜情緒，也是本作戀愛張力的重要來源。

玩法以戀愛劇情、日常生活與表演者養成三者結合為主軸。在日常中可以與兩位姊妹互動，例如聊天、舞蹈練習或協助酒吧工作，並透過不同選項影響好感度與觸發特別事件。同居生活也帶來大量溫馨與心跳的橋段，包括共同用餐、意外的近距離接觸、彼此照顧或練習中的小插曲。作為表演者養成遊戲，玩家需要替姊妹安排訓練課表，如體能、技巧、舞蹈排練與舞台演出等，這些選擇會直接影響她們能否在比賽前達到最佳狀態。劇情則會根據玩家在養成中的選擇、酒吧經營成果以及與哪位姊妹的情感發展較深而分歧，最終導向不同結局，包括姊姊線、妹妹線或額外路線，並搭配大量語音、CG展現故事魅力。

於2026年3月26日推出，目前尚未開放玩家評論，但因美術品質高、劇本陣容強、角色設定極具吸引力，加上同居生活與雙女主角的戀愛結構相當受歡迎，使其未上市就已獲得廣泛關注。唯一的隱憂在於育成深度與劇情厚度是否足夠支撐重複遊玩，但以Entergram過往作品的穩定品質來看，大多玩家依舊抱持樂觀期待。

整體而言，《甜星姊妹》是結合浪漫日常、角色成長與舞台夢想的甜蜜系戀愛養成作品。雙胞胎姊妹的鮮明魅力、精美的角色設計、帶有暖意的同居情節與舞台競賽的張力，使遊戲擁有高度吸引力，是喜愛戀愛冒險與育成類型玩家值得期待的作品。

“Sweet Starlight Sisters” is a romance-raising adventure game built around the core theme of “accompanying twin bunny-girl sisters as they grow and pursue their dreams together.” The overall atmosphere is gentle and romantic, blending cohabitation life, performer training, and emotional development. Through daily interactions and story progression, players gradually draw closer to the two sisters—each with distinct personalities—supporting them as they shine on stage while forming a unique emotional bond among the three in everyday life.

The game is created through the collaboration of popular illustrator Hiiragi Ringo and scriptwriter K. Baggio, known for his work on the Sengoku†Koihime series. Its style is bright and delicate, making it a highly anticipated title among romance-game fans.

The story begins in a vintage bar named “BACCHUS”, nestled in a corner of the city. After the protagonist’s grandfather passes away, he inherits this old establishment. Business has declined, far from its former glory. To revive the bar, he seeks help from his childhood friends—the twin sisters Anya and Saya, mixed-race siblings well known for their pole dancing and stage performances. They are local stars not because of innate talent, but because of relentless practice and unwavering effort.

As the protagonist takes over the bar, the sisters move into his living space. From then on, the three begin their cohabitation life while aiming for the shared goal of winning a major stage competition. The story unfolds through bar management, performance training, and everyday moments, during which the emotional bonds between the protagonist and the sisters deepen from childhood friendship into something far more intimate.

Anya, the elder twin, has a Swedish mother and Japanese father. Her gentle appearance and calm demeanor give off a mature, soothing presence. She takes quiet care of both her sister and the protagonist, embodying the archetypal “good big sister.” Despite her rational, analytical mind—making her the technical type on stage—she has the contrasting flaw of being terrible at cooking.

She has liked the protagonist since childhood but is too shy to express her feelings directly, instead showing her affection through subtle gestures. When faced with her sister’s bubbly affection, she often becomes flustered. Her private interactions with the protagonist are delicate, tender, and comforting, making her the character who brings players a strong sense of emotional security.

Saya, the younger sister, is the complete opposite. She is bright, free-spirited, outgoing, and full of energy. Also mixed-race, she radiates vitality and draws attention wherever she goes. She loves to act cute, openly tells the protagonist how much she likes him, and constantly seeks closeness with her sister.

She expresses her emotions without hesitation—straightforward, affectionate, and clingy. Although she seems carefree, she possesses a strong will, and her dedication to stage performance is no less than her sister’s. However, when scolded, she becomes discouraged immediately and needs gentle comfort from both the protagonist and Anya. Saya’s liveliness and honesty add a great amount of sweetness to the story and form a major source of the game’s romantic tension.

The gameplay centers on a blend of romance storytelling, daily life, and performer training. Players can interact with the sisters in daily scenes such as chatting, practicing dance, or helping with the bar’s operations. Choices affect affection levels and trigger special events. Cohabitation brings many heartwarming and exciting moments—shared meals, accidental close encounters, caring for each other, and small incidents during practice.

As a training simulation, players must plan the sisters’ schedules, including physical training, technique lessons, dance rehearsals, and stage performances. These decisions directly impact their readiness for the competition. The storyline branches according to the player’s training choices, bar management performance, and the emotional progression with each sister. The game features multiple endings—Anya route, Saya route, and additional routes—complete with extensive voice acting and CGs.

The game is set to release on March 26, 2026. Although player reviews are not yet available, anticipation is high thanks to its polished visuals, strong writing team, appealing character concepts, and the popular cohabitation + dual-heroine romance structure. The only potential concern is whether the depth of the training mechanics and the richness of the story will support high replay value. However, considering Entergram’s consistent quality in past works, most players remain optimistic.

Overall, “Sweet Starlight Sisters” is a sweet and heartwarming romance-raising title that blends everyday tenderness, character growth, and stage aspirations. The vivid charm of the twin sisters, beautiful character designs, warm cohabitation moments, and the tension of stage competitions together create a highly attractive experience—one that fans of romance adventures and raising-sim games can eagerly look forward to.
