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!
...and cleanse the sky's blackness!
und reinige den Fleck im Himmel!

y limpia esta impureza del cielo!
e ripulisci la corruzione nel cielo!
e limpem o que macula os céus!
Очисти небеса от тьмы!
