由Idea Factory旗下乙女遊戲品牌Otomate開發，並於2018年移植至Nintendo Switch 平台的《Code：Realize ～彩虹的花束～》（Code：Realize ～彩虹の花束～）是一款集大成的視覺小說作品。它收錄了本篇《創世的公主》以及續篇《祝福的未來》，以充滿蒸氣龐克（Steampunk）風格的19世紀倫敦為舞台，巧妙融合大量世界名著中的傳奇人物，編織出一場關於禁忌之愛、自我救贖與冒險的宏大史詩。

故事聚焦於神秘少女卡爾迪亞（Cardia），她全身充滿劇毒，凡觸碰生命都會令其枯萎，因此被世人視為「怪物」，獨自隱居於荒廢宅邸中。直到某天，她遇見自稱「紳士大盜」的亞森·羅蘋（Arsène Lupin），羅蘋帶領她逃離軍方追捕，並引入充滿齒輪與蒸氣雲霧的倫敦世界。在尋找失蹤父親與探索自身秘密的過程中，卡爾迪亞結識了天才發明家弗蘭肯斯坦、伯爵聖日耳曼、吸血鬼獵人凡赫辛與工程師巴比康。這群個性迥異的紳士在共同冒險中與少女建立深厚情感羈絆，各自心懷目的卻相互交織，構成一段充滿張力的冒險故事。

在操作與系統設計上，展現視覺小說極高的製作水準。透過閱讀精美文字與選擇對話分歧來推進劇情，核心在於「好感度系統」。每個選擇都可能觸發隱藏對話或進入特定角色路線，使劇情深度大幅提升。特別強化動態演出，角色對話時會眨眼、口型變化並有細微肢體動作，搭配質感豐富的背景美術與蒸氣龐克特有的機械齒輪音效，營造極強沉浸感。

Switch版本整合兩部作品，支援流暢觸控操作，方便玩家翻閱歷史紀錄（Log）或快速存檔。續篇《祝福的未來》提供本篇結局後的後日談（After Story）與外傳故事，使玩家能深入了解各角色的過去與未來。系統選單中豐富的畫廊、音樂鑑賞與詞典功能，詳細介紹遊戲中引用的文學典故與科學背景，讓戀愛之外也能享受世界觀的厚度。

在市場評價方面，獲得壓倒性讚譽，被認為是「乙女遊戲領域的標竿作品」。評論特別肯定其「史詩般的劇本張力」，認為本作成功將戀愛元素、冒險動作與政治陰謀完美結合，劇情深度遠超一般戀愛模擬遊戲。畫師miko精緻華麗的角色設計，加上與蒸氣龐克氛圍相得益彰的交響配樂，使藝術表現達到巔峰。

雖然部分評論指出共同路線篇幅較長，初次遊玩時節奏稍慢，但其感染力強的結局與豐富角色成長曲線完全彌補這一點。總結而言，本作不僅吸引女性玩家，也因其紮實的世界觀設定受到視覺小說愛好者高度評價。它成功將歷史與文學人物賦予全新生命，成為 Nintendo Switch 上不可或缺的情感體驗佳作。

Developed by Otomate, the otome game brand under Idea Factory, and ported to the Nintendo Switch in 2018, Code: Realize ～Rainbow Bouquet～ (Code：Realize ～彩虹の花束～) is a definitive collection of the series. It includes the main story, Cardia: The Princess of Creation, and the sequel, The Future of Blessings, set in a 19th-century London imbued with steampunk aesthetics. The game cleverly weaves legendary figures from classic literature into a grand visual novel epic centered on forbidden love, self-redemption, and adventure.

The story revolves around the mysterious girl Cardia, whose body is filled with deadly poison that withers any life she touches. Viewed as a "monster," she lives in isolation within an abandoned mansion until she encounters Arsène Lupin, a gentleman thief. Lupin helps her escape from military pursuit and introduces her to a London filled with gears, steam, and intrigue. During her search for her missing father and the secrets of her own existence, Cardia meets a cast of extraordinary gentlemen: the genius inventor Frankenstein, Count Saint-Germain, vampire hunter Van Helsing, and engineer Babbington. Though each has their own motives, their shared adventures foster deep emotional bonds with Cardia, creating a story rich in tension and adventure.

In terms of gameplay and systems, Code: Realize ～Rainbow Bouquet～ showcases high production values for a visual novel. Players advance the story by reading finely crafted text and making dialogue choices, guided by the affection system. Every choice can trigger hidden dialogues or unlock specific character routes, significantly enhancing narrative depth. The game features dynamic character expressions, including blinking, lip movement, and subtle body gestures, complemented by detailed backgrounds and steampunk-inspired mechanical sound effects, creating a strong sense of immersion.

The Switch version integrates both games, adding smooth touch-screen controls for reviewing logs or quickly saving progress. The sequel, The Future of Blessings, offers post-story content and side stories that deepen understanding of each character’s past and future. The menu includes a rich gallery, music player, and lexicon detailing the literary and scientific references throughout the game, allowing players to enjoy the world-building alongside the romance.

Code: Realize ～Rainbow Bouquet～ received overwhelming praise, recognized as a benchmark title in the otome game genre. Critics particularly applauded its epic narrative tension, noting how it seamlessly combines romance, adventure, and political intrigue, delivering a depth far beyond typical dating simulation games. Miko’s exquisite character designs, paired with symphonic music that complements the steampunk atmosphere, elevate the game’s artistic presentation to its peak.

Although some reviews mention that the shared route is lengthy and the pacing can feel slow for first-time players, the emotionally impactful endings and detailed character growth more than compensate for this. Overall, the game not only captivates female players but also appeals to visual novel enthusiasts due to its immersive world-building. It successfully breathes new life into historical and literary figures, making it an indispensable emotional experience on the Nintendo Switch.
