Riku Sen is a lieutenant in the Gaku Ka Army.


He is clean-shaven and wears heavy armor along with a crested helmet.


A cool-headed soldier, he is nevertheless annoyed by Ko Zen’s excessive worrying over their leader, Mou Ten. In addition, his diffident attitude and lack of ambition frustrated Ko Zen to no end. On the other hand, he does take his duty to watch over his commander seriously. Despite being praised as a spear wielder with skills that would give Ou Hon a run for his money, he himself is humble enough to insist Ou Hon's spearmanship is on a completely different level.


After joining the Gaku Ka Unit, Riku Sen's achievements in the battlefield over the years earned him the rank of lieutenant in Mou Ten's independent unit.
