Nagami Yuu was a high school student aiming to become a light novel author, but he always stuck failing at the preliminary screenings. Then one day his little sister Suzuka comes to him with a shocking confession--she's won first prize in the new author contest!
Fine! I'll be your stand-in 
if that's what you want!
Also schön!
Ich werde deinen Platz einnehmen!
¡Bien! ¡Seré tu doble!
¡Bien! ¡Seré tu doble!
E va bene! Allora a farti 
da controfigura ci penserò io!
Tudo bem! Pode deixar comigo!
Ладно, стану я твоим
подставным лицом!
