Stay Nights Crisis

—The Holy Grail War—
A ritual held in Fuyuki City by magi grasping to reach the Root.
Seven magi, known as Masters, gather to compete over possession of the Holy Grail, which possesses the power to fulfill any of its bearer's wishes.
They fight other Masters for supremacy by summoning Heroic Spirits, known as Servants, called upon by the Holy Grail.
However, throughout the past four Holy Grail Wars, history has yet to see a single victor.
During the Fourth Holy Grail War ten years ago, Shirou Emiya was saved from amidst the fires of war by the self-proclaimed mage Kiritsugu Emiya.
The young Shirou started living with Kiritsugu and persistently asked for instruction in magecraft, much to the mage's disapproval. On the night prior to Kiritsugu's death, Shirou promised his adoptive father that he'll become a Hero of Justice.
Fast forward to the present.
On one quiet eve, Shirou gets involved in the Holy Grail War and is assailed by a Servant.
Just as the glint of steel threatens to take his life, a girl clad in knightly armor appears to stop the fatal attack.
The Servant, who came to the rescue of the would-be Hero of Justice, and the Master, saved by the Heroic Spirit of the Sword; their fates are in motion...

The girl “Fine” wakes up in a prison.
In this game, you control her as she tries to escape safely.
It is an escape adventure game.

Lost parents, abused, abandoned…
There is no end to the number of people who are taken in by the facility for various reasons.
The name of the support facility for such students is Tanpopoen.
Today, a young girl named Hinako has come to the facility again.
However, there is a cruel and ruthless staff member there.

A kind-hearted succubus, Remuria, an outlier among the succubi, won't kill her prey and cannot ignore injustice. One day, she helps Ariandelle, a half-elf slave, escape captivity. However, Remuria soon discovers that her own village is also in danger. Teaming up with Ariandelle, the two set out on a journey with shared goals: to free all the enslaved elves, defend the succubi village, and uncover their enemy's ultimate goal. But that's not the end of their struggle, as Ariandelle is afflicted with Soul Crusher—a powerful mental spell that only Remuria can temporarily alleviate with her special powers. To break the spell completely, they must track down the caster. Experience the game in two separate modes. Enjoy the story in Novel Mode, where you follow the plot and get to know the characters. In RPG Mode you can explore, fight enemies, and work to push the story forward. Attack enemies first to gain the upper hand with a preemptive strike, giving you an advantage in turn-based battles. Plan ahead to use your resources carefully to overcome tough challenges and keep moving forward.
