Thirteen-year-old Elena is there, as is Pamela (who's a hidden unit if you have Yggdra Union save data).
Five characters were announced, but only four spaces remain. :|a Looks like Pamela is most likely to get shafted.
Nessiah is still moe in Kousaki's art style~. These scans are awful, but I still wanna make icons from them. ;x;
They changed his voice actor.
The new guy is a voice actor named Yonaga Tsubasa, who according to his Wikipedia page has a high voice and specializes in playing young men and boys.
He'd better be really fucking good, because Miyake was so awesome as Nessiah that it's going to take a lot to top his performance.
