Ruan (ルーアン地方) is the westernmost region in Liberl. It borders on the Azelia Bay to the west, the Zeiss region to the southeast, Valleria Lake to the east and the Bose region to the north. Its provincial capital is the City of Ruan.
During the Hundred Days War, Ruan was captured by the Erebonian Empire like most of the other regions until new orbment technology and blitzkriegs allowed the Liberl Kingdom to liberate the area and take it back. Ruan also used to rely on fishing for its economic resource until the Orbal Revolution allowed orbment-controlled technology to allow for tourism to attractions such as the Langland Bridge.
During the chapter which revolves mainly in Ruan, Estelle and Joshua arrive at the Manoria Village where they first meet Kloe Rinz, bumping into her after ordering some food at the inn/restaurant. After they have their picnic looking at the ocean by the windmill, Estelle bumps into an orphaned boy named Clem who sneaks away with her Bracer Emblem. After running around town, they learn that he lived in the Mercia Orphanage so the bracers go there in pursuit.
At the orphanage, they run into Kloe again after a misunderstanding where Estelle looks like she is putting Pat in danger. She receives back her bracer badge and they meet Matron Theresa during a snack of apple pie. Kloe then offers the duo to escort them to the City of Ruan where they agree. After they reach Ruan, they learn from Carna, a senior bracer, the bracer guild chief, Jean, was in a meeting at the moment so they cannot sign into the guild yet. Therefore, Kloe guided them around town where they meet the Ravens, the town's delinquents who tried to flirt with the ladies. Before trouble emits before the two groups, Mayor Dalmore and his secretary Gilbert interfered.
Later, the group meets Jean, done with the meeting, and signs into the Bracer Guild. They then look for a lodging to stay at where they meet Duke Dunan who forces them to give up their penthouse as he is royalty (related to the Queen Alicia II as her nephew). The two then just stay with Nial who offers them a room as he has a couple extra beds.
Soon the orphanage is then burned to the ground by unknown assailants overnight. The bracers went to investigate which lead to Pat trying to fight back the Ravens leading to Kloe assisting the two into fighting them. Agate then comes into place, stops the Ravens, and he takes over the mission of the burned orphanage. In order to help pay off the money for it, Estelle and Joshua volunteer to help out with the play at the Royal Jenis Academy to build up money for Matron Theresa. During their school days there, after the play, Joshua notices a certain white haired man running amok. Joshua chases him to no avail. Unfortunately, soon after the money was earned, the Matron, the orphans, and Carna were ambushed by black-masked soldiers and the money was stolen.
While investigating the matter, the party runs into Agate again where he joins them in searching for the assailants which lead to the Varenne Lighthouse. There they meet the Ravens, now powered up by an unknown source, and they defeat each group as they advance. Soon they see Gilbert having a meeting with the black-masked soldiers which lead to him getting injured and Agate chasing after them. The rest of the group then agree to report back to Jean about how the mayor is connected to the burning of the orphanage.
The party then goes up to the mayor to interrogate him on that but he sends his "pets" to dispatch of the party members which fail and it made the mayor use his artifact to stop time. However, the Black Orbment neutralizes its effects and a whole chase scene ensues which leads to the mayor getting caught by the Royal Army while fleeing on his boat.
After the matter was resolved, Jean gave the party their branch recommendations and head to Zeiss (Region), promising Kloe that they'll meet again at Grancel.
Ruan is the first region Estelle returns to after her promotion to senior bracer. It is here she reunites with Kloe and Olivier and helps to solve the case of several mysterious, ghost-like sightings across the region. After investigating the area the group determines the source to be the old schoolhouse behind Jenis Academy where they confront Bleublanc, who had been projecting images of himself using a an ancient orbment in the ruins below.
Ruan loses all orbal power after the appearance of the Liber Ark, necessitating Estelle and her group to arrive with a Zero-field generator to bring the phones back online.
Gilbert Stein staged an attack on the academy after figuring out the royal princess disguised herself as a Jenis student. Estelle Bright and team head to the academy rescuing the students and staff. Being a coward, he resorts to kidnapping Kloe's friend, thinking to be the princess. The result with Gilbert being defeated, kidnapping the wrong person, and being punished by Campanella.
