Grisaia: Chronos Rebellion

Shonan Saika Academy, a high-achieving all-girls school in Kanagawa Prefecture.

One day, Marin Tachibana, along with her best friends Mashiro Saotome and Kiyoka Jinguji, experiences a special day.

It begins with meeting an unusual new transfer student, Shizuku Kujyo.

A beautiful girl with a calm and dignified demeanor.

Meeting her feels like déjà vu...

While showing her around the school, they stop by an observation deck, where Marin finds a four-leaf clover.

There is a tradition at this school:

If you press a four-leaf clover found on the observation deck into your student notebook, your wish will come true.

(I want to get closer to her. To spend more time with her...)

With this wish, Marin gives Shizuku the "coincidental" four-leaf clover she found.

This act becomes a turning point, bringing Marin and Shizuku closer together with the help of Mashiro and Kiyoka. However...

"Please, stop worrying about me. I don't want to just be protected..."

"Shizuku, we're friends, right?"

A storm threatens to tear them apart.

It is deeply tied to a "secret" Shizuku is hiding and a "trauma" from Marin's past.

The story follows the growth, mutual support, and cherished memories of the four girls.

Will Marin and the others find their personal "clover" (happiness)?

In this game, you play as Fujita Hiroyuki, a high-school student who seems to have more interest in romance than in his studies. In his school there are several pretty girls, and his goal is to be nice to one of them, to make the right decisions when talking to her, and ultimately to win her heart.
 
Remake of the original PC version featuring a completely revised script, with some of the heroines having completely different stories as a result, full voice acting for all characters except the protagonist, new art, and mini-games.

In a future over one hundred years hence...

All the people in the world have awakened to unique abilities called 'Dunamis'. As these special powers become rooted in people's everyday lives, their value system changes, and those who lack powers are the ones who are treated as strange. With the passing of the ages, the environment has changed completely, while society has greatly regressed. The overall population of mankind has diminished as well, and most of the world is made up of wastelands and greenery dotted with the weathered ruins of the world before.

The City of Raillore.

With brickwork buildings like those of the Middle Ages, developed over land graced with lush greenery and rivers. With the concept of nations gone from the world, Raillore exists as something of a self-sufficient commune. The Order of Security and Regulatory Knights - AKA the Regulatory Corps - serves as a government organization in charge of handling crime prevention and other tasks that require force of arms.

But things begin to change as odd incidents take place, one after another...

Those possessing abilities different from those of Dunamis begin to appear. The people fear this power and the phenomena it causes, and those capable of it are designated as ‘Errors’. The sudden appearance of these Errors is regarded as a disease, and the handling of Errors is placed under the jurisdiction of the Regulatory Corps. As people tremble in fear of the vicissitudes of the changing times, there are those who try to open a way to the future with their own strength...
 

Uchihama Academy has seen an increase in enrollment in recent years and as a result, a new school building will be constructed.

On one day, he stays in the school late at evening because he got slightly injured by the judo club and is healing his wounds in the infirmary. Suddenly, the building shakes. Shocked, he runs up the stairs to where the shaking seems to have centered, and there he encounters a mysterious naked girl, who at first appears to know him. On the next day this girl, Yui, seeks out the astronomy club, expressing her desire to join.

Fraise feels that the relationship between siblings is the most important while Shigure feels the happiness of her catgirls is what is most important.

Motivated by their desire to make sure the other is able to fulfill their love for Kashou first, the battle between catgirl and girl begins!
