Despite having numerous husbands through her long life she is known for being committed to each of her past husbands and staying with them till the end.
Excel Walters was present during the founding of the Elfrieden Kingdom five hundred years ago, and resided at Lagoon City. Unlike Castor Vargas and Georg Carmine, she had managed to weather the food crisis in her duchy, due to the fact that Lagoon city had a port and trade was far easier. Over her long life, she had married and gave birth dozens of times. Once her children reached adulthood, she would disown them and marry them off into several influential families. At present, the number of her descendants would fill a small town or a large village.
After the abdication of Albert Elfrieden, Excel secretly sent her granddaughter Juna to the Elfrieden Kingdom during Kazuya's call out for talented people. She was very impressed by the reforms enacted by the new king and the descriptions of him by Juna. She was also disgusted by the corrupt nobles' disdain of the new king.
During the Final Counsel, Excel decided to pledge her allegiance to Kazuya and urged her fellow Dukes to do likewise. However, both Castor and Georg rebelled, thereby starting the One Week War. Unknown to them, Excel was already stationed at the fort of Altomura in preparation to combat the invading Armidoria Army. She would also lead a naval unit to threaten the Republic of Turgis, thereby forcing the invading army at Nelva to withdraw.
After the conclusion of the One Week War, the Army, Navy and Air Force were disbanded and combined into a new National Defense Force. Reluctantly, Excel accepted the appointment as supreme commander, until a more suitable replacement was found. She would also offer her granddaughter Juna as a Secondary Queen to Kazuya. Later on, she oversaw the development of the aircraft carrier Hiryuu and the appointment of her son-in-law Castor as its captain. She also began teaching the four Queen Consorts in 'bridal training' and also Kazuya in 'husband' duties.
