About Daibanchou -Big Bang Age-

In Daibanchou -Big Bang Age-, Japan is fractured after the cataclysmic appearance of the Hell Hole, which granted dark B-crystals the power to create superhuman "Special Students." As a new leader emerging from the Tokyo school, you must unite the warring factions and bring order to a land torn between military might, supernatural horrors, and sky pirates. Build your forces, master strategic combat, and reshape Japan's destiny in this epic region conquest SLG.

A Fractured World Reborn from Chaos

Step into a compelling narrative set in an alternate Japan, where a single catastrophic event reshaped the entire nation. The story begins with the eruption of the Hell Hole (also known as the Demonic Hole), which twisted the Japanese archipelago beyond recognition and led to the emergence of mysterious B-crystals. These crystals grant extraordinary abilities to a segment of the population, primarily the youth, who become known as Special Students. Initially unified under a powerful leader who formed the Student Union (S.U.), Japan has once again splintered into powerful, hostile factions. Your journey begins in the Tokyo school, where you rise as a potential new force capable of challenging the existing powers and potentially changing Japan's future forever.

1.  The Cataclysm and Its Aftermath: The game's world is built upon the profound disaster of the Hell Hole, an event that not only altered the geography but also gave rise to B-crystals. These crystals bestow "B-power," creating a new class of superhumans and plunging the isolated nation into a dark age ruled by violence and fear.

2.  A Nation Divided by Warring Factions: Japan is no longer a unified country but a battleground for several major powers. You will encounter the military might of the PGG in关东 (Kanto), the terrifying vampires of the Nightmare Eyes in Hokkaido, the disciplined ninjas of the NPI, the fanatical Holy Flame knights in Kansai, and the violent Skull Serpents sky pirates in the tumultuous九州 (Kyushu) region.

3.  Your Role as a Leader: You are not just a fighter; you are a strategist and a commander. Your task is to emerge from the school grounds, build your reputation, and challenge the dominant factions to bring the entire country under your control.

Strategic Gameplay and Nation-Building

Daibanchou -Big Bang Age- is a deep, region-conquest strategy game that challenges your tactical mind. The game is structured across three distinct chapters, each expanding your scope of influence, from controlling a single school to commanding the entirety of Japan.

1.  Three-Tiered Campaign Progression: Your conquest is divided into three main phases: the "School Chapter," where you secure your local base; the "Prefecture Chapter," where you expand your dominion across a larger region; and finally, the "National Chapter," where you vie for control over all of Japan against the major factions.

2.  Resource and Force Management: A key to success is managing the enigmatic B-crystals. Harvested as "B-stones," they serve as both the currency of this world and the essential power source for your Special Students. You must manage their extraction and distribution to fund your campaigns and keep your elite forces combat-ready.

3.  Diplomacy and Recruitment: Strength lies not only in armies but also in allies. You can capture defeated enemy commanders and persuade them to join your cause. Furthermore, building relationships with key characters and making strategic choices about whom to ally with can unlock new story branches and powerful companions.

Unique Content and Lasting Appeal

Beyond its core strategic loop, the game is rich with content that encourages multiple playthroughs and deep engagement. The world of Daibanchou is filled with memorable characters and interweaving stories that respond directly to your decisions.

1.  A Vast Cast of Characters: The game features a wide array of unique characters, each with their own backstory and motivations. Many of these characters, including several heroines, have dedicated story arcs and "Five-Star Events" that unlock as you deepen your bond with them.

2.  Branching Narratives and Multiple Endings: Your choices have significant consequences, leading to major narrative divergences. For instance, your actions in the Prefecture Chapter can determine which major faction you confront later, locking and unlocking different character recruitment opportunities and story outcomes.

3.  Legacy and Influence: Originating from the renowned Japanese developer AliceSoft, this game is a spiritual successor to Daiakuji and shares its DNA with the popular Big Bang Beat fighting game series, which is set in the same universe. This connection offers a deeper lore for fans to explore.
