In YE 36, the YSS Eucharis found a crashed starship full of Rixxikor. After a violent first contact, the Yamatai Star Empire gained the attention of the Interstellar Kingdom of Kuvexia, which had been using Rixxikor as cannon fodder. King Kalapom declared that Yamatai was a nuisance and ordered the Kuvexian Military to begin invasion plans.
By early YE 37 Kuvexians had established a forward operating starbase and their ships were depositing Rixxikor in Yamatai Space on planet Higaflan in the Higaflan star system. The Star Army engaged in direct combat with Kuvexian Navy ships. Later that year, the Star Army also encountered a Rixxikor colony ship in the Nougfran System.
In YE 38, conflicts escalated when the Rixxikor mounted an attack on the YSS Eucharis, attempting to steal it. The Eucharis retaliated by destroying the Graxlat scrapyard where the Rixxikor colony ships were being made. Following this, the Star Army First Expeditionary Fleet mounted a large attack on the Kuvexian Navy's forward operating starbase. This large, direct attack on the Kuvexians led to the start of the war.
1) The Interstellar Kingdom of Kuvexia has made known threats of imminent invasion of the Yamatai Star Empire, which have been relayed by its Naval officers to the officers of the YSS Eucharis and to Star Army Intelligence.
2) The Navy of the Interstellar Kingdom of Kuvexia has already attacked starships of the Star Army of Yamatai such as the YSS Eucharis on multiple occassions,
3) The Navy of the Interstellar Kingdom of Kuvexia established a military starbase for forward operations against the Yamatai Star Empire in the Kikyo sector,
4) The Interstellar Kingdom of Kuvexia has attempted to disrupt the Kikyo Sector economically by dumping millions of Rixxikor into our area of space, who, by all accounts, are destitute, disorderly anarchists who are prone to violence.
5) Forces associated with the Kuvexian Kingdom have attempted to steal Star Army of Yamatai military ships and equipment, and have kidnapped Star Army personnel.
Recognizing that the Interstellar Kingdom of Kuvexia has made unprovoked acts of war against the Star Army of Yamatai, the Yamatai Star Empire, and the greater Kikyo sector as a whole;
Therefore I resolve, by the power and authority invested in me by the Constitution of the Yamatai Star Empire and by the Empress of Yamatai, Her Imperial Majesty Himiko I, Sovereign of the Yamatai Star Systems, the Elysian Celestial Empire, Gashmere, Ohara, Essia, and the Outer Colonies, that:
1) A State of War now exists between the Yamatai Star Empire and the Interstellar Kingdom of Kuvexia, and that commanders of the Fleets, Organizations, and Bases of Star Army of Yamatai and Yamatai's planetary defense forces are authorized to utilize their full resources to make war against the Kingdom of Kuvexia and its allies to bring this war to a successful and victorious end.
2) I also request that all resources of the Imperial government are pledged to the same.
Ketsurui Yui Commander, Star Army of Yamatai
