Nagare Akiba

One of the four Chosen of the Beast Spear who is very well versed at using the shakuja and other holy weapons to deal with monsters. While initially appearing laid back and composed, he is later revealed to have a dark drive to satisfy the boredom in his life due to a lack of any challenges until Tora came along. This leads him to side with Hakumen no Mono and sabotage Ushio's plans.
