The game is told of an old story that involves a young man with red hair named Adol Christin.
A long time ago there was a kingdom called Ys and it grew and flourished under the protection of the two Goddesses. However, later in time the kingdom became known as Esteria and its divine history was disappearing. The only ones left that still worship the Goddesses are descendents of the one who once preached the Goddesses' will.
As time went on the people began mining silver from nearby mountains and things started to progress for the people. The people built towns and wildlife became more rich and plentiful but at the same time demons and monsters began to appear around them. Eventually there were so many monsters the people had to hide away in fear. Now, Esteria is known as a rumored land that is known worldwide.
The story starts with a young red-haired boy who heard about the rumors of Esteria and wanted to find out if the stories were true himself.
Adol Christin – He's a 17 year old teenager who is a swordsman and adventurer. He is known for is red hair that resembles a flame and his clear black eyes. Born and raised in a small mountain village with no name in eastern Europa. After turning 16 years old, he begins his adventure by getting a boat from Promalock and set sail for the land of Esteria after a year and a half on foot.
Dogi – He is the trusted man of the head of the thieves guild. Dogi is known for having a uplifting spirit and he is mostly known for his amazing strength. He went into the Tower of Darm in search of treasure but has not returned yet.
Lilia – A young and pretty girl who saw Adol fall from the sky and came to his aid. She is a cheerful girl that nothing gets in her way but there is one thing she doesn't know, she's suffers from a disease that might take her life soon.
Reah – A mysterious harmonica player who showed up in Minea city and began playing music for the people. She eventually settles in the city but no one knows who or where she really came from.
Feena – A young woman who was imprisoned in a magic sealed jail cell, left only with a mask to keep her company. She can only remember her name and nothing else.
Goban – The head of the thieves guild. He's the type who steals from the rich and gives to the poor. He hides out near the Tower of Darm where no man would go, so no one dares to bother them.
Sara Tovah – Sara is the fortune-teller in Minea and is the descendent of Tovah. She has seen visions of the return of an ancient evil in her crystal ball and is now awaiting for the brave hero who's is destined to fight that very evil.
Jeba Tovah – She is Sara's aunt and also a descendent of Tovah. She lives in the small village of Zepik on the main island of esteria.
Maria – A young woman from the village of Ramia in Ys. She was kidnapped so that she can be used as a human sacrifice for the demon. She was taken to Campanile of Lane to see her end.
Tarf – A trouble maker from the Colony of Lava in Ys. Thanks to his love for adventure and curiosity, he was kidnapped and set in prison.
The game uses a system called “Bump System” where players just bump into the monsters to fight and defeat them. The strategy is to bump them from behind or off-center. If players attack from the front, they will deal less damage and also receive damage themselves.
In Ys II, players will eventually get magic and they can either press or hold the button to unleash the magic depending on what weapon or item they are holding.
One of the additions is the new and updated soundtrack called Chronicles, which is basically a re-work with real musical instruments. There are also two other soundtracks to choose from and one of them is the "Complete Soundtrack" which is the music released with Complete (PC) in 2001. The other soundtrack is the classic "PC-8801."
Players have the option to choose any of the soundtracks in the start menu at any time in the game.
Besides the entirely brand new character art done for the PSP called Chronicles, the player has the option to also choose Complete, which is the art used in the 2001 PC release.
The game art can be chosen at the main menu when either starting a new game or in the options menu.
The PC version of Ys I & II Chronicles includes features from both the PSP version and the older PC version Ys I & II Complete. You are able to play the game in a full screen viewport or use the classic framed view from Complete.
