Oko is seen wearing a purple kimono, with blue and yellow triangles as borders. Her obiage is blue and black striped, and her obi is a pair of live female pink snakes. She wears slightly high geta shoes which are pink in color. From her pastel blue hair sprouts two small black horns and a pink lily is placed as an accessory. Oko is depicted as everyone's friend; the one that all get along with. She is very nice, polite and usually quiet. When she comments on things, she's usually very sharp tongued though her comments are executed with a sweet smile on her face. She is also the object of many of the show's male cast desire, the most notable being Karauri. Oko however, shows no romantic interest whatsoever in any of the characters and usually keeps all her relations friendly but nothing more than that. Alas, i should be noted that she has mentioned the fact that were she to have interest in someone that she would value personality above all else.

Hozuki's Coolheadedness
Hell is a bureaucracy, and business is running smoother than ever thanks to the demonic efficiency of Hoozuki, chief deputy to Lord Enma, the King of Hell. Whether offering counsel to the Momotarou of Japanese folklore or receiving diplomatic missions from the Judeo-Christian Hell, the demon who runs the show from behind the king's imposing shadow is ready to beat down any challenges coming his way into a bloody pulp. Metaphorically, of course... The poster boy for micromanagement and armed with negotiation skills worthy of Wall Street, Hoozuki no Reitetsu follows the sadistic and level-headed Hoozuki as he spends his days troubleshooting hell. With an abundance of familiar faces from popular Japanese legends and East Asian mythology working middle management positions, this referential and anachronistic dark comedy brings new meaning to the phrase "employer liability." Just how hard could it be to manage employees from hell, anyway? [Written by MAL Rewrite]
