《愛之吻2》（日文：アイキス2，英文：Ai Kiss 2）是由日本Entergram公司發行、於2021年3月25日推出的戀愛冒險類遊戲，對應Switch與PlayStation 4平台。是GIGA旗下「Kiss系列」的第十部作品，延續前作《愛之吻》的設定與世界觀，同時加入全新角色、場景與支線劇情，帶來更豐富、更完整的校園戀愛體驗。

劇情背景設定在距離城市稍遠、以藝術與設計為主題的學校「有杜學園」。玩家所扮演的主角在入學當天，與兒時玩伴三枝彩雨與三枝日向兩姊妹久別重逢，並認識多位個性鮮明、魅力各異的學姊們，如成熟可靠的菅野順子與活潑開朗的櫻田杏。隨著故事的推進，更多新角色陸續登場，包括冷靜神秘的鳥須十和子，以及文靜認真的葛城七瀨等人，與主角一同生活在共同創作的工作室空間中，展開一段段充滿曖昧與心動的校園日常。

操作方式上，作為典型的視覺小說戀愛冒險遊戲，主要透過閱讀對話與內心獨白來推進故事，需要在關鍵時刻做出不同的選擇，這些選擇將影響主角與角色之間的關係，並最終決定故事的發展方向與結局。支援Joy-Con、Pro控制器操作，也能使用觸控螢幕輕觸選擇，操作方式簡單直覺，讓人可以輕鬆專注於劇情本身。

在關卡與內容設計方面，採用章節式結構，每個章節專注於不同女主角的故事發展。隨著與角色相處的過程中累積親密度，解鎖個人支線、特殊事件以及戀愛告白情節。此外，遊戲中還安排許多學園生活的日常活動，包括學園祭、夏日泳裝派對、煙火大會等，每個活動都搭配專屬CG、語音與劇情演出，讓整體故事氛圍更加生動立體。

上市後在日本戀愛遊戲圈中獲得不錯的評價。普遍肯定它細膩柔和的畫風與角色人設，尤其是女主角們性格設定飽滿，各有獨特的魅力，能依個人偏好選擇不同類型的戀愛對象。劇情部分則維持前作清新溫馨、帶點甜蜜曖昧的風格，搭配全語音演出與精緻CG，令不少玩家投入於每段戀愛故事之中。

不過，部分玩家也指出遊戲整體結構偏向線性，雖然能藉由不同選擇體驗多結局，但劇情走向依舊比較固定，缺少像部分戀愛模擬遊戲那種高度自由探索與互動的要素。此外，作為戀愛遊戲，以故事與人物情感刻劃為主，對於偏好策略挑戰或大型開放世界探索的玩家來說，可能較難獲得高度耐玩性。

總結來說，這是專為喜歡戀愛題材、角色互動與溫馨校園日常的玩家打造的作品。延續Kiss系列一貫溫暖輕鬆的戀愛氛圍，同時在人物互動、劇情鋪陳與畫面演出上展現成熟水準，特別適合喜歡日本戀愛視覺小說與日式戀愛冒險遊戲的玩家，在Switch上也能隨時隨地享受這段青春校園的戀愛時光。

"Ai Kiss 2" (Japanese: アイキス2, English: Ai Kiss 2) is a romance adventure game developed and published by Entergram in Japan, released on March 25, 2021, for the Nintendo Switch and PlayStation 4 platforms. As the tenth title in GIGA’s long-running "Kiss Series," it continues the setting and world established in the original Ai Kiss, while introducing new characters, locations, and branching storylines to deliver a richer and more complete campus romance experience.

The story is set at Yuto Academy, a school located slightly away from the city, known for its focus on art and design. Players take on the role of the protagonist, who, on the first day of enrollment, reunites with his childhood friends — sisters Ayame Saegusa and Hinata Saegusa — after years apart. He also meets several distinctive and charming upperclassmen, including the mature and dependable Junko Sugano and the cheerful, energetic An Sakura. As the story progresses, more new characters appear, such as the cool and mysterious Towako Torisu and the quiet, earnest Nanase Katsuragi. Together with the protagonist, these characters share their daily lives and creative experiences in a communal studio space, leading to an unfolding series of ambiguous, heart-fluttering campus moments.

In terms of gameplay, Ai Kiss 2 follows the traditional style of visual novel romance adventure games. Players primarily progress through the story by reading dialogue and the protagonist’s internal monologues, making choices at crucial points. These choices influence the relationships between the protagonist and other characters, ultimately affecting the direction of the story and its multiple endings. The game supports both Joy-Con and Pro Controller inputs, while also offering touchscreen controls for easy and intuitive selection, allowing players to comfortably immerse themselves in the narrative.

The game adopts a chapter-based structure, with each chapter focusing on the story development of a different heroine. As players deepen their relationships with characters, they unlock personal side stories, special events, and romantic confession scenes. Additionally, the game includes a variety of school-life events — such as school festivals, summer swimsuit parties, and fireworks displays — each accompanied by exclusive CG illustrations, full voice performances, and dedicated cutscenes, making the story world feel even more vibrant and immersive.

Upon release, Ai Kiss 2 received a positive reception within Japan’s romance game community. Players widely praised its soft, delicate art style and carefully designed character personalities, especially the well-developed heroines, each with their own unique charm. The story maintains the series' trademark light, heartwarming, and sweetly ambiguous tone, enhanced by full voice acting and high-quality CG artwork, drawing many players deeply into each romance scenario.

However, some players noted that the game’s overall structure leans more toward a linear experience. While multiple endings can be unlocked through different choices, the overall progression of the narrative remains relatively fixed, lacking the high degree of freedom and interaction seen in some other romance simulation titles. As a romance-focused visual novel, the game prioritizes storytelling and emotional connections over strategic challenges or expansive open-world exploration, which may limit its replayability for players who prefer those genres.

In summary, Ai Kiss 2 is a title made for fans of romance, character-driven stories, and cozy school-life adventures. It continues the warm, relaxed atmosphere of the Kiss Series, while delivering polished character interactions, refined storytelling, and attractive visuals. It’s especially recommended for players who love Japanese romance visual novels and dating sims — now made even more accessible for casual play on the Nintendo Switch, allowing you to enjoy this youthful campus love story anytime, anywhere.
