In volume 4 we meet the final members of the zweilt, a male and female pair named Sairi and Lia who just arrived back in town after being on a mission overseas. With the exception of Kuroto, who resigned from a promising semi professional gaming career, Sairi and Lia are the only other two who have not kept out of the public eye. I am wondering how they are going to go about doing official business in their home country, where they are most famous, while not letting anyone figure out that they are powerful warriors trying to defeat an otherworldly evil. I also hope to see more about how their relationship came about and what the future holds for them, they are the second pair of zweilt that were not partners in their previous life, one of their partners having been killed and unable to be saved for reincarnation.
Besides the new characters, there are more battles and the promise of more secrets and information about the past to be revealed.
I am now halfway through the collected volumes and I am not looking forward to it being over so soon. I might have to find a way to watch the anime. I have been thinking about subscribing to Crunchyroll or something similar so that I can watch all the manga that I read. I think at the end of this series I will have made a decision.
