Adol is flown to the floating island of Ys by the twin goddesses, Feena and Reah. After a violent arrival, he sees a bunch of monsters, and passes out. When he comes to, he awakes in the Doctor's office in the village of Lance with all his equipment and armor are gone except for the six books of Ys. His injuries have healed, and the doctor, noticing the books, comments about the mine. A young girl by the name of Lilia (Lilian in the English dub) tells about the abandoned mines of Rastini, and how she found a shrine in there. She offers to guide Adol, but he declines her offer, claiming it to be too dangerous. He travels off, but before he leaves, a villager named Sada gives him a sword. While Adol's in the mines, he falls down a chasm, and ends up in the shrine he was looking for in the first place. At the same time, a group of monsters arrive in Lance Village to select the next human sacrifice. At the last moment, Lilia shields the intended victim and is chosen as the sacrifice. Despite the objections of her mother Banoa and the other villagers, Lilia goes with the monsters of her own free will. Deep in the underground Shrine of Toal, Dark Fact appears before Adol. Instead of the evil sorcerer terrorizing Esteria in the previous OVA, he has reformed to the side of good, and gives Adol some more backstory about the Black Pearl. He then gives Adol the power of the Six Priests, enabling him to use magic. When Adol returns to Lance Village, he finds out that the villagers have been offering human sacrifices to monsters to maintain peace. When he finds out Lilia's going to be the next sacrifice, he's determined to rescue her, much to the chagrin of the village elder. He reaches Lilia, who by that point is willing to sacrifice herself for the good of the village. Adol charges in and starts attacking the monster who's in charge of the sacrifice, Velagunder. Velagunder tosses Adol aside easily, and destroys his sword. Adol hears Fact's voice, and uses a fire spell against

Feena and Reah, the two goddesses of Ys, their fate is revealed as they arrive in a destroyed shrine located in the glacier part of Ys. Lilia springs Adol out of his imprisonment in the village, as repayment for rescuing her previously, and the two run towards the glacier which is forbidden for the rest of the villagers to enter. Four villagers defy this law, and pursue Adol and Lilia into the glacier. Adol convinces the four to spare the lives temporarily so they may see for themselves past the glacier that the world does not end, but continues far into the horizon. They rest at the shrine where Feena and Reah made themselves home at. Lilia stays to rest with Feena and Reah while the four villagers and Adol head to the other side of the glacier. While they're away, the girls are attacked by Dalles, a wizard working for Darm. Feena and Reah tell Lilia to run, and give her a pendant to give to Adol when she sees him again. Lilia runs while Feena and Reah are taken before Darm, and are imprisoned inside a crystal. While Lilia's running, a group of monsters attack her, but one of the beasts turns on his comrades, allowing Lilia to escape from them and run where Adol was bound to be. Meanwhile, Adol and the villagers reach the other side, only to have their view of the surface be blocked by clouds. The villagers are about to smite Adol, when a monster comes up and tells the villagers to leave Adol to him, and to walk away. Adol begs for a sword, but the villagers comply to the monster's wishes, and leave Adol to his fate. Adol calls upon the power of the priests once again, and fights with magic fire balls. One of the villagers gets a change of heart, and decides to run back to help Adol out. The others follow suite, and as Adol and the monster are colliding projectiles, the clouds clear away to prove to the villagers that there is a world outside of Ys. The villagers start helping Adol fight the monster, to which Adol finishes off with a huge fire ball. Once they're do

It opens with a flashback of Keith's sister being sacrificed to the monsters by the tolling of the bells. Keith rushes in and slays the beast who turns out to be his sister that was transformed into the beast. The monsters laugh at his folly, and transform Keith into a beast. Back in the present, Adol approaches a bridgeman who won't let the bridge down for Adol to go to the village of Ramia because his son, Tarf, has been kidnapped. Adol rushes off to rescue Tarf, who meanwhile has befriended his cell mate, the traitorous monster Keith who's been chained up in the prison. Adol sneaks his way in to the prison, steals a sword from a guard, and slices everyone down. Adol finds Tarf, and is about to rescue the boy when he's attacked by a slug monster. Adol's sword is immediately dissolved by the monster's blood, and Adol starts throwing energy balls at the creature. Keith sees Adol in peril, and breaks out to help him. He attacks the monster and holds him off long enough for Adol to cast a huge energy ball into the mouth of the creature, killing it. Keith rushes off afterwards while Adol takes Tarf back to the bridgeman who gladly lets him cross, and also gives him some Cleria armor as a reward. On the other side, Adol finds Ramia destroyed, and finds out the monsters had come and captured most of the villagers of Ramia. One of the villagers from Lance that travelled with Adol rushes into Ramia, and tells Adol he and another villager, Sada, had escaped from Lance which had also been attacked by monsters, and most of the villagers including Lilia were captured as well. Sada took a Cleria sword, and rushed off by himself towards Solomon Shrine. Adol resolves to head to Solomon Shrine with nothing but his spells. Adol meets with Sada, and Sada informs Adol that his girlfriend, Maria, is the next to be sacrificed, and that if the bell rings five times, she's a goner. Adol and Sada reach the top, but not in time, and Adol finds the wizard, Dalles, up there. Adol wonders how

Darm begins powering up to bring evil to the world while Dogi, Goban, and Ruta arrive in Ys, and start conversing with the goddesses who communicate with them through a goddess statue. They ultimately decide to destroy the black pearl to eliminate evil altogether. They hand Luther a golden harmonica, and tell him to climb to the top of the bell tower, and play the goddess tune that Adol knows. Keith and Lilia walk into the room, and Keith goes berserk after hearing the plan to destroy evil. Dogi holds off Keith, and Lilia begs them all to stop fighting. When Luther tells them he doesn't know the goddess tune, they tell him to seek out Adol. Dalles enters the room and destroys the goddess statue. Keith breaks up his fight with Dogi and starts attacking Dalles. Dalles quickly fends off Keith, and goes off to meet Adol. Keith almost attacks Lilia, but calms himself down at the last minute. Lilia tells Luther to give her the harmonica because she knows the tune the goddesses spoke of. She runs off to climb the tower while Keith chases after her to try and stop her. The other three head off to find Adol. Dalles finds Adol's first, and attacks him relentlessly. Adol finds out from Dalles that Darm is the one in charge, and just as Dalles is about to kill Adol, Darm kills Dalles for outliving his usefulness, and tries to tempt Adol to join him in creating an evil utopia. Keith catches up to Lilia, and reveals to her that if she succeeds in destroying evil, she will disappear as well since Keith reveals that her mother came to him in the past when Lilia was an extremely ill baby, and he fell in love with the mother immediately. He agreed to help save Lilia's life, and to do so, he had to sacrifice a monster, and infuse her with monster blood, which is the reason she didn't turn to stone. Darm starts trying to take complete control of ALL monsters, and Keith starts going berserk while Lilia gets affected as well from the monster blood in her, and starts going weak. Keith los
