Isuta (イスタ, Isuta) is the younger sister of Asuta and subordinate of Vamirio.


Isuta is a young looking girl with cat ears, amber eyes and long black hair.


Isuta is very caring of her older sister and her well being.[2]

Isuta feels uncomfortable at the sight of blood, especially when she was little.[3][4] She is a very clumsy girl, a crybaby, a coward, and a worrywart. However, despite these traits, she is a hard worker and her willpower is superior to even Hyura's. She loves her sister more than anything else.[5]

Her dream is to serve the Red Heavenly King, Vamirio.[6]


Ahh... IsutyEdit

Isuta had trouble finding interest in anything, while her sister took interest in almost everything. Isuta grew up with Asuta and Hyura and became very close friends with each other, even though Hyura and Asuta would sometimes have fun at Isuta's expense.

One day, Asuta's and Isuta's village was attacked by monsters whom managed to break through the village barrier. However, they were saved by Vamirio. From that incident Asuta and Isuta were inspired to become soldiers of the empire. They eventually become personal subordinates of Vamirio.[7]

She graduated from Demon King Gwyn Castle Academy. Since Hyura and Asuta traveled after graduation, Isuta decided to go on her own trip until she was old enough to take the entrance exam. She barely passed the entrance exam and had low grades for many years, but she got promoted through her efforts and willpower. As a result of her resolve, she became the close aide of her heart's greatest desire, the Red Heavenly King.[8]

Isuta communicates with Asuta and informs her sister something that could help.[10]
