As Soon as He Became the King, He Was Selected by the Escape Game.

I am the new moon in the fourth house. An ordinary chaebol young man who has just become the new seventh king, the Colorless King. What he likes most every day is teasing his ice sculpture sister Shinomiya Kaguya, teasing the golden retriever, and talking about life with mature and beautiful seniors... In short, he enjoys a short and leisurely daily life. However, the turning point often comes suddenly, when a game called Escape comes to the world. Everything is completely different. Unfortunately, he, the new Colorless King, was chosen to become a fugitive. And the teammates are even more like a group of delicate and extremely "familiar" big sisters...
