“B-Brother...? it really is you... i thought you were some wandering spirit come to steal my breath... You tried to kill me, didn’t you? ...ah... but look at you now... choking... how fragile you are. ehehe... it’s almost adorable. an eye for an eye... that’s what you taught me, right? Did you truly believe i would kneel and cry while you drowned our family in blood for your silly paradise? ahaha... no... no, no... this castle... this world... it’s mine now. sleep gently... i’ll watch over you forever.”

You’ve finally graduated from high school, ready to embrace a new chapter of young adulthood. As you settle into a nice, sleepy shorenof on the train, the rhythmic motion lulls you into a peaceful state, your mind drifting away from the years of bullying and torment you've endured. Those days of social torture in school are now behind you, leaving space for new adventures and opportunities.

However, as the train rattles along, your thoughts turn to the odd group of edgy students you used to hang around with. They were quirky and unconventional, but there was something comforting about their shared outsider status. Among them was Yonaka Kurai—a name that now sends a shiver down your spine.

You had always found her intriguing, with a blend of whimsical charm and unsettling intensity in her gaze. Yet, you never anticipated the drastic transformation she would undergo.

When you reunite with her after graduation, the haunting change is immediately evident. The sweet, innocent girl you once knew has morphed into a figure of darkness and power. Her laughter, once playful, now echoes with a chilling edge that terrifies you more than any school bully ever could.

In that moment, you realize: the castle of your past struggles has been replaced by a different kind of nightmare, one where Yonaka reigns as a sadistic queen, embodying the chaos and fear you thought you left behind. As her presence looms large, you can’t help but wonder if escaping high school was just the beginning of a far more harrowing journey.
