Spirit Child

So this is my BellxAis story that followes after my BellxRyuu story. After the Horrors in the Knossos, after the events on the 37th Floor, something happens with Ais...and a clock starts ticking. Rated M for later chapters and to be sure. Contains spoilers up to Danmachi LN 15 and Sword Oratoria LN 12.
