1) Milly is basically a girl who can't stand other people getting hurt (hence why she saved Sagi once). She is really arogant to Guillo, but nice to Sagi, but when dramatic moments happen, she fight bravely.
2) Guillo is basically a puppet, but with emotions lol. It is really mean to people, is really loyal to Sagi, and can't stand Milly. Guillo is basically a hero with an attitude.
3) Kalas is a young man who had his little brother, and grandpa killed by Giacomo, which causes a spirit to come help him. At first, during the first part of the game, he only cares of what is happening to himself. Later on though, he wants to help stop the evil.
4) Gibari is a laid back kind of guy. When serious stuff happens, he becomes angry, and fights for what's right.
5) Giacomo is absolutely ruthless in both games. In BK 2, he is a teenager who seeks power to beat Sagi. In BK 1, he is a ruthless man, who has incredible power. When Kalas finally defeats him, he wants to help stop the evil god known as Malpercio, but he is now dead.
6) So you're not going to include Sagi?
7) Is Gibari going to die?
