However, she likes and is curious about human culture, and collects the remaining items of human after other impurities kill them.

She is often joking and does not care about the misunderstanding of humans. However, when she talks about the fate of the Twin Star Exorcists, her expression turns serious.

History
Chinu is the first impurity Doman Ashiya created and had the chance to evolve. In her Shinja (True Snake) form, she hated human, attacked them and was shown to be besieged by them as well. Later at some point, she chose to stand in a neutral position, mainly for her interest for humans.

After a long walk for two months, it turned that Chinu lives in the Magano near Kyoto, and collects items of human culture for entertainment. While Benio was nervous and eager to restore her power, Chinu joked to her. Out of impatience, Benio asked her to be serious and talk about how she can recover her powers.

Chinu agreed to help her, but warned her that she must know the truth of Twin Star Exorcists, the battle between human and impurities, and the consequences for getting back power. She then used the mental link to show Benio, the city of Kyoto from a thousand years ago, and the two geniuses Abe no Seimei and Doman Ashiya who created the mechanics called Twin Star Exorcists. After that, she told Benio that, the females of the Twin Star Exorcists are in fact humanoid impurities, and are all genetically related to Doman. The Twin Star Exorcists would use their lives to give birth to Miko. She also reminded that, many females of Twin Star Exorcists who came to see her went mad, escaped from their destiny, or died in the process of transformation. Only two to three succeeded in transformation but eventually failed.

Benio was shocked, and Chinu scolded her to encourage her. She later begin the ceremony to help Benio transform, and she ordered Kamui to go outside to act as a guard.

Right before the ceremony, Benio asked her why she helped human, she told her there are many reasons, but mainly, for that if human failed she no longer can enjoy music. She also told Benio that, the ceremony would destroy her human body, turned that into ashes, in order to release the power.

When Kaguya emerged and heavily injured Kamui, she thought that the worst interruptor had came. She tried to let Benio focus on their ceremony and successfully awakened Benio's hidden power.
