Nagare Hisui

Nagare Hisui is the Fifth and Green King, and runs the Green Clan, JUNGLE. He has the ability to channel himself through a green bird named Kotosaka, and use it as a medium for communication.

Personality
Despite being a King, unlike the strong bonding relationship of Kings and clansmen shown by other longtime rival clans such as the Blue and Red, Hisui apparently shows little to no concern over the safety of his own clansmen. This is evident when he was willing to sacrifice Douhan Hirasaka, who is considered an esteemed clansman based on her abilities, by activating JUNGLE's bomb despite how she was still in the area where she would likely be caught by the blast radius; Douhan was apparently surged with both disbelief and anger as she was unaware of how her King would easily make such decisions. Thus, Hisui likely sees his clansmen as expendable and is will not hesitate to sacrifice them, much less inform them to be prepared, to achieve his goals.
