毘盧遮那戰姬 ～一樹之風～ 是 毘盧遮那戰姬 ～源平飛花夢想～ 的官方續作 Fan Disk（FD），由 Otomate 與 Red Entertainment 再次聯手推出。作品延續前作在乙女遊戲市場中的高評價，並透過補完與延伸劇情，進一步深化整個源平世界的情感厚度與角色魅力。

本作同樣登陸 Nintendo Switch 平台，日版於 2022 年 3 月 31 日推出，繁體中文版則於 2023 年 11 月 23 日發售。作為 Fan Disk，其核心定位並非全新主線，而是建立在既有劇情基礎上的「延伸與補強」，主要提供給已通關前作的玩家進一步沉浸。

在劇情結構上，採取雙主軸設計，清楚區分為「後日談」與「IF 路線」兩大內容方向。後日談承接前作各角色的戀愛結局，描寫主角與包括 源賴朝、平知盛 等人在戰後動盪局勢中的共同生活。雖然時代背景依然帶有不安與壓力，但敘事重心明顯轉向角色之間的情感深化，使整體「戀愛濃度」較前作顯著提升，成為本作最受好評的部分之一。

另一個亮點則是 IF 路線的設計。前作中原本僅作為配角登場的角色，在本作中被正式升格為可攻略對象，讓玩家得以探索「如果當初選擇不同人」的全新可能性。這些新增路線並非簡單補充，而是具備完整劇情架構與情感鋪陳，尤其像佐藤兄弟與平重衡等角色，其故事深度與情緒張力獲得玩家高度評價，成功從配角轉化為具有獨立魅力的主線角色。

系統層面則大致承襲前作，並在細節上進行優化。例如若玩家持有前作存檔，可解鎖額外的連動短篇劇情，提升系列整體的連貫性。同時，針對 源平合戰 相關的歷史名詞，遊戲內建詞典功能提供即時解說，降低理解門檻。演出方面，戰鬥場景與關鍵 CG 的表現也更加精緻，使整體沉浸感更為完整。

從市場反應來看，普遍被視為一款「補完度極高」的 Fan Disk。其最大優勢在於成功回應玩家對前作的期待，特別是在戀愛描寫上的加強，使角色關係更加立體且具說服力。同時，新角色路線的品質也遠高於一般 FD 水準，展現出製作團隊的誠意。

然而，作為 FD 的本質也帶來一定限制。整體遊戲時數相較本傳明顯縮短，對於期待長篇劇情的玩家而言可能略顯不足。此外，部分路線依然維持系列一貫的沉重敘事風格，即便加入更多情感描寫，仍難以完全擺脫悲劇色彩，對玩家情緒仍有一定負擔。

綜合而言，《毘盧遮那戰姬 ～一樹之風～》是一部針對既有粉絲打造的高品質延伸作品。它不僅補足了前作在戀愛描寫上的不足，也透過新增路線拓展了角色可能性。若已體驗過本傳，這部 Fan Disk 幾乎是不可或缺的延續；但若未接觸前作，則建議先從本篇入手，才能完整理解其中的情感脈絡與角色魅力。

Birushana: Rising Flower of Genpei ~Ichijuu no Kaze~ is the official fan disc (FD) sequel to Birushana: Rising Flower of Genpei, once again developed by Otomate in collaboration with Red Entertainment. Rather than presenting a completely new standalone narrative, this title expands upon the original game’s story, deepening character relationships and enriching the emotional scope of its Genpei-era setting.

Released for the Nintendo Switch on March 31, 2022 in Japan, with a Traditional Chinese version following on November 23, 2023, the game is designed primarily for players who have already completed the original. Its structure and content assume familiarity with prior events, focusing on continuation and alternate possibilities rather than reintroduction.

The narrative is divided into two major components: After Stories and IF Routes. The After Stories continue from the romantic endings of the original game, exploring the lives of the protagonist and her partners—such as Minamoto no Yoritomo and Taira no Tomomori—in the aftermath of war. While political instability and lingering conflict remain part of the backdrop, the tone shifts more heavily toward emotional intimacy, offering significantly more romantic development than the main title.

The IF Routes represent one of the fan disc’s most notable additions. Several popular side characters from the original are promoted to full romance options, each receiving their own branching storyline. These routes diverge from earlier points in the narrative, presenting alternative character dynamics and outcomes. Importantly, they are not treated as simple bonus content; each route is fully developed, with strong character arcs and emotional payoff, contributing meaningfully to the overall experience.

In terms of gameplay, the system largely follows the traditional visual novel format established in the original, with minor enhancements. Save data from the first game can unlock additional crossover episodes, strengthening continuity between the two titles. A built-in glossary helps explain terms related to the Genpei War, making the story more accessible to players unfamiliar with Japanese history. Presentation has also been refined, with improved CG illustrations and more polished dramatic sequences.

Reception has been generally positive, especially among existing fans. The After Stories are widely praised for addressing one of the original game’s main criticisms—the relatively restrained romantic content—by delivering more emotionally satisfying and character-focused interactions. The newly added routes have also been commended for their depth and narrative quality, elevating what could have been minor characters into compelling leads.

However, as a fan disc, the game’s scope is naturally more limited than a full-length release. Individual routes are shorter, and the overall playtime is reduced. Additionally, while the romantic elements are strengthened, the series’ characteristic tone—often marked by tragedy and emotional weight—remains present in several storylines, which may not appeal to players seeking a purely lighthearted experience.

Overall, Birushana: Rising Flower of Genpei ~Ichijuu no Kaze~ serves as a high-quality extension of the original game. It successfully expands character relationships, enhances emotional depth, and provides meaningful alternative narratives. For those who have already experienced the main title, it is a highly recommended continuation; for newcomers, starting with the original game is strongly advised to fully appreciate its narrative impact.
