Creepy Bro-con Older Brother vs. Hateful Tsundere Younger Brother
About
Princess Guest lives in a certain castle.
By her side, an exceptional guard always serves. A man more loyal and reliable than any other.
—But he has a discarded twin brother.
Only the older brother was chosen and welcomed into the castle. The younger brother was abandoned and raised as a shinobi.
Unlike his brother, his life was filled with dirty work.
Perhaps because of this, the younger brother has harbored an abnormal obsession and inferiority complex toward his older brother since long ago.
The younger brother sets his sights on the Princess his brother protects so dearly—Guest.
