Brilliant as Brocade

Died unexpectedly? Don't worry, I can come back to life at full health right where I fell. Separated from my little brother? No problem, we can reunite in the underworld. Fighting alone? No way! I've got mighty generals from the underworld by my side! Getting bullied? How could I allow that? I'm the King of Hell's big sister. Who would dare mess with me?! Huh? You want to know what the position of “Big Sister” entails? Ahem, I give orders to cute ghosts below and the King of Hell above. That's me~
