The heroine is the God of War, who is both good and evil just like the ancient Po Jun. She doesn't like Athena and only talks about deceiving people. Even if you are a decent character in the original book, you will usually bleed to death even if you are assassinated. But the heroine is different. Just like the name, she separates like ions and fuses and resurrects like water.
Eight male protagonists have been confirmed.
Hmm... I decided to keep Shion because he has no regrets. The animated version of Shion has only appeared in a few episodes.
The heroine picture is from the Gandharva King in "Sacred Legend", the one who made Lily. This is the only anime woman who fits the female goddess of war.
