After the abdication of Albert Elfrieden, Excel secretly sent her granddaughter Juna to Parnam 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.

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.
