The Fall of Kirlandas

Summary: the main character, Chunami, is a very high-ranking character whom one day gets met with a girl named Elly, who's in search for her missing sister. She helps Elly in boredom and curiosity but ends up finding more about her (Chunami)'s past and soon after gaining the position of higher ranking, war occurs. However, this time with a new leadership. *This does include romance as a side-plot* *Main character is badass in my view but not relatable* (examples: Nanno from the Girl From Nowhere or Mira from Alice in Borderland) *The male lead is, in fact, SIMPABLE* *The plotting is a bit complicated and in the end after I'm finished I'm willing to create a chapter explaining EVERYTHING*
