Joshua was born on 12-20-1185 of the Septian Calendar in his hometown of Hamel Village up north. There he lives happily with his family until a tragic event happens seven years later. Due to a tragic event in his past, Joshua became basically catatonic from the trauma, not eating, talking, or even playing his harmonica.
One day, a traveling magician offered to mend the boy's broken heart, if Joshua would work for his organization. His caretaker agreed, and Joshua's very mind was manipulated into the will of Weissmann. Joshua becomes the Black Fang, a full-fledged enforcer who ruthlessly assassinate his targets and innocents without a pause.
Five years before the start of Trails in the Sky, Joshua was tasked with assassinating Zemuria's S-Rank Bracer; Cassius Bright, but was eventually outmatched by the staff-wielding bracer. As Joshua was about to be eradicated for his failure, Cassius defended the boy regardless of his actions and decides to adopt him into the Bright household. Years passed, Joshua befriends his adoptive sister Estelle Bright with no recollection of his past until years later.
Prologue: A Father's Love, A New Beginning
5 years later, Joshua has become a brother to Estelle Bright, as the two train to become Bracers. As the game starts, the two are taking their final test, overseen by their mentor and close friend Scherazard Harvey. Taking various tests about learning the tools of the trade, they soon become Junior Bracers. After hearing that two local boys went into the dangerous Esmelas Tower, Joshua and Estelle move to rescue them. Once they do, Cassius intervenes, saving the four children.
Estelle is less than satisfied that she needed her father's help for the mission, but Joshua cheers her up. That night, Cassius reveals that he has to leave for some business in the Erebonian Empire, and when he leaves, Estelle and Joshua take over the jobs he left for them in his absence, including helping a Royal Academy girl named Josette. The two hear that the mayor of Rolent had been robbed, and find that Josette was the culprit - she was actually a Sky Pirate. Tracking Josette down to Mistwald, Estelle and Joshua battle her, and are victorious. However, she escapes into an airship, and the duo find out that she is from the Capua family. Returning to Rolent, the two hear that the airship Cassius took to Erebonia, the Linde, has disappeared over the Bose region.
Chapter 1: Disappearance of the Linde
Joshua, Estelle, and Scherazard move on to Bose to investigate. Meeting with the mayor of Bose, who requests a Bracer investigation, the group goes to visit General Morgan at Haken Gate. They learn that Morgan has an intense hatred for Bracers, and tells them that the Capua family has demanded ransom for the Linde, before figuring out their true identities and refusing to cooperate further. They meet a man named Olivier, who travels back to Bose with them. The group has no further leads except Nial, a Liberlian News reporter who traveled to the Esmelas Tower in Rolent with them. He tells them that there is apparently a witness of a large airship in Ravennue Village.
Traveling there, they question the child, who states that the ship went north. Going north, the group finds an abandoned mine with Kyle Capua unloading the cargo of the Linde. Defeating him, Kyle gets away, and the group investigates the ship. Finding no passengers, they return to report but are taken into custody by the military.
While in jail, there is a burglary in Bose's south block, clearing the party of any suspicion, and they are released. And for that, they immediately gone to Bose`s south block to investigate. There they questioned few civilians about the incident. They get the info that a man in the inn near Lake Valleria knows something. Thus, they immediately gone to the tavern, and asked the man, knowing the culprit is coming for the night. So they wait until night comes, and the info was correct. They notice the two probable culprits: Josette and Kyle Capua but only sees with another suspicious man coming from the small boat. They had an idea to find fast the Capua`s airship. They found it stationed near the tower, and when the Capua associates come back, they sneaked in the lower parts in the airship within the cargo, and wait until it returns to their secret base.
When they made it to the Capua's secret base in Nebel Valley, they got out of the airship after everyone left and they ambushed the two guys on lookout. When they moved on throughout the area, they first knocked out some of the Capua's goons. Later, they found where the hostages were and after taking out more of the Sky Bandits. They went into the hostage's room to ensure their safety. To their surprise, Cassius wasn't among the hostages as they learned from one of the crew members of the airship, Cassius left right before the plane took off for Bose. Next, they found the room holding Josette, Kyle, and Don so they came in to capture them.
After the brawl ended with both sides, Don seems to genuinely lose all his memories of the recent events like kidnapping the hostages. Kyle soon threw a smoke bomb for the Capuas to escape from the clutches of the party. Soon the party left the room to chase the Capuas to their airships. Along the way, the rest of the Sky Bandits tried to distract and fight the party to slow them down in vain. When the party reached the airship, they found that the Royal Army led by Alan Richard came to apprehend the bandits already with Nial and Dorothy tagging along for photo-journalism.
After the whole incident was settled, a strange package came to Joshua and Estelle. Itunknownan unknown artifact called a "Black Orbment", whose recipient is Cassius Bright, and a letter from someone called "K". The letter directed that the "The Black Orbment" would be sent to "Professor R" as well. Joshua decided with Estelle to travel around Liberl's regions to investigate this mysterious artifact, while simultaneously building up to the bracer ranks. Schera and Olivier both decide to go back to Rolent, in which Schera needs to report back at the Rolent Guild while Olivier just wants to hang with Schera to his heart's content, sharing her drinking interest.
Chapter 2: Madrigal of the White Magnolia
After saying their goodbyes to the people they've met in Bose, Joshua and Estelle head to the checkpoint at the Krone Pass and meet Agate.

They headed back to Magnolia to gather clues from Teresa and the orphans who are temporarily housed at the village's inn. A solution is found to restore the orphanage and the culprit found. It's suspected a man with white hair that used to go visit them was involved but remained dubious due to his kind nature.
The Brights decided to take a break and spend time with their new friend, Kloe at the Jenis Royal Academy, and becoming friends with the others students. During then, Estelle feels relieved about Joshua's change of atmosphere, revealing that Joshua never had male friends since his arrival at Rolent. At the school festival, Estelle and Joshua have been selected to participate in a play, with Joshua forced to play the princess. Everyone is amazed how the costume suits to him, much to Joshua's reluctance and chagrin. The play is a success in gathering funds for rebuilding the orphanage. Joshua noticed and pursued a man in the old school building that seemed linked to his past, but the man escaped.
Later the group finds out that unknown assailants attacked the Matron, even with Carna by her side. Agate also appears in which the recent assault is related to the arson incident. Kloe used Seig to find the location of the villains at the Light House. There they encounter the Ravens, but they are boosted up with deadly power and fighting without reason. After defeating the Ravens, the party discovers Gilbert conversing with the arsonists disguised in black clothing. After a hostage ordeal that led to them escaping and Gilbert injured, Agate follows them in pursuit while the rest of the party reports back to the guild. Before they return to the guild, the party decides to pay a visit to Mayor Dalmore to check if he does have any relation to the crimes that happened.
They discover it is true that Mayor Dalmore was the true arsonist, but manages to disable the group with the Chronos Wand, a strange artifact that can freeze its targets into place. The Mayor threatens to kill Estelle, provoking Joshua to give a stare to redirect the attempt towards him. Before the mayor pulls the trigger, the Black Orbment goes off and somehow disables the wand's orbal powers.
