Kara no Shojo: The Second Episode

In the period known as "pre-war," when Japan was taking its first steps into conflict...
In the snowy mountains of the west, there is a settlement called Hitogata.
In this place, with its strange custom of worshipping a clay doll called Hinna-sama, a woman is killed on the night of a festival.
The villagers unanimously refer to this incident as "Hinna-sama's Curse." They say that she was cursed for worshipping Hinna-sama despite being unworthy.

December, 1957

It's been almost two years since Kuchiki Toko was abducted from her hospital room.
Tokisaka Reiji's sister, Yukari, saves a man attempting to commit suicide.
The man is a victim of "Hinna-sama's Curse," which has resurfaced in the present...
Tokisaka Reiji acts to sever the delusions that span the war.
All the while carrying his own delusions about Toko in his heart...
At the same time, a religious group that was thought to have disbanded six years ago begins to move again.
What could it be scheming?

Even if Heaven brings down a curse, it is human hands that enact it.

Kara no Shoujo 2 is the largest and most intricate of IG's games yet, with a fully voiced cast, including the protagonist. The Detective System has evolved with each entry in the series. It consists of four parts: "Story," "Exploration," "Investigation," and "Deduction."

Each part is seamlessly integrated into the story, creating an enjoyable game, rather than merely a visual novel.
