it was about some young prince who loved military tactics. he was actually someone from japan (yep, isekai), and the nation right now is in a danger situation ever since the death of his father. he started to reform the military and political policy with the help of his childhood friend aka fiancé.

all of the character's looks like an elf (they have a little pointy ears), and their name sounds like Greek.

edit: ah, and the childhood friend aka fiancé's father is the kingdom/empire's military chief or something.. he has a bulky body and some kinda bakaoya

San Tairiku Eiyuuki?
