After the party completes the four trials, they fall into a trap by Symonne, a fallen Seraph who works under Heldalf. During his journeys, it is discovered that Rose has a high level of resonance and she becomes Sorey's Squire, joining the party along Dezel, a Seraph of wind who was guarding Rose as part of a secret agenda. After recovering, Sorey learns that there are four shrines with trials that a Shepherd must accomplish in order to become stronger and decides that he must clear them first before challenging Heldalf again. During the skirmish, Heldalf, the Lord of Calamity himself, appears before Sorey and he is almost killed, being rescued in the nick of time by an assassin called Rose. When a war between Hyland and the neighboring Rolance Empire breaks out, Alisha is used by Hyland's military as a leverage to force Sorey and his friends to take part in a battle. However, Alisha's low resonance with the Seraphim takes a toll on Sorey's body and she is forced to leave the group. During their travels Sorey and the others have a short encounter with Zaveid, a rogue Seraph of wind who hunts down Hellions on his own accord, and befriend Edna, an earth Seraph who also joins the party. After Sorey reunites with Alisha, who is revealed to be a princess to the Hyland Kingdom, she becomes his "Squire" to fight the Hellions by his side, and the party starts traveling the continent purifying the Hellions and searching for the main source of the malevolence that plagues the land into an Era of Chaos, the individual known as the "Lord of Calamity". While looking for Alisha's whereabouts, Sorey has an encounter with Lailah, a Seraph of fire known as the Lady of the Lake, who makes a pact as his Prime Lord, granting him the power to purify the Hellions and making him a Shepherd. Once Alisha departs back home, Sorey and Mikleo have a short clash with a Hellion called Lunarre and fearing for her safety, they decide to leave the village in search for her. The game begins with a young human called Sorey and his friend Mikleo, a Seraph of water exploring some nearby ruins when they rescue a human girl, Alisha, and bring her back home in the village of Elysia.
