First of all, i dont know when wil 18th will came but i dont know the time-spam between volumes. I would like to ask about your ideas.
Secound for who think, war game about hestia vs freya familia. Its possiblity is low. A goddes who charmed evryone will get attacked by rebels(charmed-orario cizitans and adventures also gods and goddes.*). She will be send to tensei ig imidiently cuz she broke the rule. No war games. However there is a change of loki familia vs freya familia in normal fighting between familias like freya vs ishtar familia. It was not legal(idk what to say*) like "war game", that is legaly fight beetween familias. Thats all ƪ(‾ε‾“)ʃ . Stay safe and have good days. Talking in this site is awsome and makes me happy. Also someone writed zues to zeus : )
