雛ちゃんファクトリー　東方 is a free role-playing game developed by ISY for the Android platform. In this game, players find themselves on a deserted island where they encounter a character named にとりちゃん, who is conducting research and experiments on clones based on the character 鍵山雛. However, the experiments go awry, and the clone 雛ちゃん manage to escape and take over the entire island.

Players must gather and train the clone 雛ちゃん, capturing and creating new ones from scratch. They can synthesize and strengthen the clones, aiming to build the strongest team of 雛ちゃん and reclaim the island from the rogue clones.

雛ちゃんファクトリー　東方 features a wide variety of 雛ちゃん characters, ranging from those wielding weapons and wearing costumes to those transformed into monsters. Players can collect various 雛ちゃん, master their abilities, and engage in synthesis and battles to raise them into powerful fighters.

The game is completely free to play, with no in-app purchases or stamina system. Players can enjoy the game at their own pace, with no restrictions on when they can play. Additionally, the game includes pseudo-battle elements for added excitement.

Please note that due to the development schedule, the storyline progression is only partially completed. More quests and 雛ちゃん characters will be added in future updates.

※ "雛ちゃん" refers to the character "鍵山雛" from the 東方project.
