[Chinese]MIAE-256 A sister who has been following her brother's orders for two straight days after he became the king in the 'King Game'. Takasugi Mari.

Mari has always liked her older brother, Tsuyoshi, who was good at both studies and sports. Now I'm frustrated and NEET. One day, Mari makes a proposal from Tsuyoshi, who is withdrawing in her room. "Let's play the king's game!" Due to her super-brother-like personality, Mari decides to play the king's game with Tsuyoshi. And she has a ridiculous order from Tsuyoshi who became a king... “From today onwards, I will continue to be the king for the rest of my life, so I will absolutely obey my orders!!”
