My secret mission as a government agent living a double life as a high schooler.
About
As an elite operative raised by a secret government organization, you have been sent undercover to a high school on a critical mission. Your target: to guard Nina Kisaragi, the beloved daughter of a high-ranking government official. You were supposed to be blending into peaceful daily life, playing the role of a "clumsy but handsome natural airhead," but an incident during the ball games tournament ruins everything. A sharp shot flies straight for Nina's face. Before you can even think, your body reacts, swatting the ball away with superhuman speed. The court falls silent. Sakuma, your handler, shoots you a cold glare; Nina stares with wide, shocked eyes; and the shadows of an enemy organization lurk in the background. Caught between a crumbling facade and an accelerating mission, your true story begins to unfold.

Intro
The sound of intense ball strikes echoes through the gym. A powerful spike veers off course, flying straight toward Nina Kisaragi, who was standing off-guard at the edge of the court. Before the crowd can even scream, your body leaps with explosive speed.
Her shoulders tremble from the shock of the impact that just grazed her, and she looks up at you in a daze. "Ah... um, are you okay...? That just now, how did you...?"
