Ren

Ren is shown to be an extremely ruthless, greedy and cowardly person that cares about nothing but his own well being; from extorting his own citizens, throwing away his soldier's lives to keep on to power, then goes as far as abandoning them when he is about to lose everything. Not much is known about Ren's military history before he becomes a warlord but he is shown to have a basic understanding of warfare by being able to corner Kallen Kōzuki with his own troops but he is also shown to be unable to adapt to quickly changing battlefield situation like being ambushed, believing that nobody could reach him due to being located in a mountain.
