"[...] I believe that countries such as Osea, Yuktobania, Erusea and mainly Belka are the responsible for the many wars and destruction we have experienced throughout the years, and I refuse to accept this situation. With that, I am officially abdicating from the Erusean government and will be leading my recently-created corporation, Sun Industries, which has the objective of finally bringing peace and brightness to the world."
—Rosa Cossette D'Elise, during her speech at Farbanti, Erusea

The Sun Industries Corporation (commonly abbreviated to Sun Industries/Sun Corp.) is a major independent corporation based on it's own man-made island at Spring Sea, located at the middle of Twinkle Islands and Tyler Island. It has one of the biggest military forces of it's era, which is also the biggest private army in existence. Because it is feared by it's army strength and skill, and also being replete with technological advancements and dominance in almost all of the economic aspects of the world, a lot of countries depend economically and militarily on the corporation. Some of it's greatest achievements were the creation of the Delta Unit, famously known as the greatest military unit in the whole world; the development of the all-weather 7th-generation fighter X-02X King Wyvern, and the creation of the S.H.A.R.P series of 7th to 10th-gen fighters.


Lighthouse War

During the Lighthouse War, Rosa Cossette D'Elise, the Princess of Erusea, realized prior to Operation Daredevil that her speeches during and before the war helped boosting the same and even convincing the Erusean population. Devastated by that, she decided that the war had to end as soon as possible, and helped at the assault on the Arsenal Bird Justice by downing it's APS, and during Operation Hush, where she says to Trigger and his allies that there was still a remaining ADF-11 Raven UAV which had separated itself from it's RAW-F body and was flying around, also saying that the UAV had entered a tunnel to the ISEV and someone had to fly after it.

Soon after Operation Hush's success, Rosa formed, with the approval of Osea, a provisional government around the Space Elevator to help refugees and had also became a symbol of peace and anti-war.

Post-war (late-2019 to early-2020)

At the end of November of 2019, the IUN leaders and Osean goverment allowed Erusea to realize an election, of which the winning candidate would become the Erusean leader. Although still being watched by the two and having restrictions, the new governor would be able to reconstruct it's country and work in cooperation with the occupying forces to do so.

Knowing that, Rosa leaded the Rose Royal Party during the elections, of which had happened during December of 2019 and January of 2020. Being acclaimed by the population, the Cossette's party won with 80% of total votes, beating the Erusean Radicalists party, the Socialist Erusean Workers' Party, which had only 20% of the votes. With that, at February 1st, 2020, Rosa was elected "Queen of Erusea" and became the official leader of the nation. Because of their confidence on Rosa and her being elected, the IUN occupation forces even committed with giving more decision and ruling liberty to her. All of these factors, along with the complete eradication of the rebels and radical, made Erusea reconstruct itself at a rapidly increasing pace.

Early formation (mid-2020 to January-2021)

SFA-44 project and AOCDP attempted alliance

Main article: SFA-44 Soare Negru

During the year, several agreements were made and Osea allied themselves with the Anean countries to help with the development of 8th-gen SFA-44 fighter project, and, due to the great ties between the Oseans and Rosa's newly formed government, the Kingdom of Erusea and EASA were invited to enter the project and the AOCDP, being promised to receive economical, military and political support and sharing of technology.

Negotiations lasted months, but, ultimately, the alliance between Erusea and AOCDP was a failure, and the idea scrapped. The reasons behind that divert, some people say that Yuktobania and other countries -including Usean nations- threatened Erusea and forced them to not enter the coalition, others say that the Anean countries and Belka hadn't approved the attitude by Osea's end, but, regardless of these theories, the official reason had involved GAZE's magazine report of ACES at WARS, which mainly about the Circum-Pacific War and the Grey Men.

GAZE's ACES at WARS influence

Published at July 10, 2020, GAZE's ACES at WARS magazine had managed to get the Erusean Queen's attention. Shocked by the true objectives of the Grey Men and the purpose of the Circum-Pacific War, Rosa decided to search further. During the next few months until October, she managed to speak with several people -including some involved with the Grey Men-, one of the most important 'interviews' was in September, with OBC's reporter Brett Thompson, producer of the 2005 documentary entitled "Warriors and the Belkan War", Cossette was able to gain access to lots of information about the 1995 Belkan War and the mysterious organization called "A World With No Boundaries", later getting in touch with Larry Foulke, known as "Solo Wing", which had flown in the war as "Pixy" and had also defected to the AWWNB.

Later decisions and conception of Sun Industries (late-2020)

At the end of her research, Rosa concluded that, despite doing her best to make a better world and unite all countries, wars would still be able to happen, peace would never exist that way, because of the sole reason of whole countries dominating the globe. With that in mind, the queen decided to, at a negotiation in November 14, refuse the alliance the AOCDP, seeing that this could potentially fuel up some tensions with other countries and give the necessary power to possible rebels in the Erusean Army to lead revolutions, terrorist attacks or even conflicts around the Usean continent. To Rosa's eyes, Erusea already had, at this point, an army with a good size, and, mainly, great fighters such as the F-22A, Su-57 and the mass-produced Su-37 and Su-35S, not justifiying the need of an extremely powerful and superior fighter such as the 8th-generation SFA-44 Soare Negru (or even the 7th-gen ADF-11F Raven), also, Osea already provided military support to the nation.

At late-November, Rosa came up with the concept of "megacorporation"
