Takasugi is set as a ghostly and violent maniac with unknown origins and unknown strength. He is sometimes taciturn and sometimes cute and chatty, and often makes the owner of the house, Gintoki, furious. When he was dying, he was picked up by Gintoki, who felt a little bored because Shinpachi and Kagura were on a business trip. Later, he became the new clerk of Master House inexplicably, and began to follow Gintoki to solve various strange commissions.
