touka is an evenkuruga mononofu (warrior) who serves lord orikakan. after orikakan is murdered by yue, she swears vengeance. after seeing the respect which hakuowlo pays to the fallen emperor, she pledges fealty to hakuoro to serve as his bodyguard and, omitted from her spoken oath but firmly kept in her mind, bear him a child. in the game, she pledges fealty because aruru and eruru convince her that hakuowlo is a good person. true to her clan's nature she obsessively follows this oath. however, even though it was part of her oath, she fails to have a baby with him, because karulau tricks her into thinking that she would become pregnant by drinking hakuoro's semen (this only happens in the game). she fights using a slim sword which she combines with her astonishing agility to execute swift and deadly attacks.
