The plan didn't work. Duh.
It's only me, who finds this entire neo-eclipse thing totally random? The time-lapse cannot be seen, so Anna and Zeref just randomly threw rocks in the air in the middle of the ocean and waited until one of the rocks disappeared? There's a random black hole in the middle of nowhere! I can't say it's a cliche, but seems weird for me.
At least the book's been opened. I wonder what's going to happen. Natsu becomes a demon, or dies? Maybe everyone forgets about Natsu? Igneel probably didn't tell him not to open it for nothing.
