MLA. Just finished the part regarding the attack on Objective 21. I can tell so much planning was done to create this piece of work. I love how it manipulates its reader's emotions. I've read plenty of novels before, but MLA is the only one that managed to make me feel attached to the characters so much. The execution is pretty good too and the soundtrack is phenomenal. I'm not surprised that it can compete with Clannad, and Nasu-verse series for the top spot.
