Ginko Murakami

Ginko Murakami (村上銀子) is a sixteen-year-old student of Seiryo High School.

Ginko is a granddaughter of Ginji Murakami, a notorious informant in the inner society, and she undertakes his conduct of dealing information. Therefore, she only treats information inherited by her grandfather that is stored online.

Shinkuro Kurenai is her intimate pal since kindergarten as he spent childhood in Ginko's home. After Shinkuro deals in troubleshooting, she supports him as an informant.

Appearance
Ginko has a short hair that reaches to her chin and wears glasses while owning a laptop for access to her grandfather's information.

She looks leaner than any of her classmates in figure, although she disapproves of her own poor figure as she tends to increase amount of meals, but never gets fleshy at all.

Personality
Ginko is apparently dishonest and gallantly in disposition, though she is actually careful, thoughtful and furtively beautiful genius. She is not good at athletics or sports at all, as she is unable to provide self-defense means.

Ginko hates Benika Juzawa and Hozuki clan, especially Yuno, but she behaves gently to Murasaki because Murasaki is an infant, therefore she is intimate to Murasaki as she had attended in behalf of Murasaki's class inspection.

Ginko tends to attend to the school earlier than any of her classmates for eating breakfast in the classroom, as she likes snack buns.

She deposits the amount of money seemingly as much as eight-figure yen.

Shinkuro Kurenai
Ginko superficially behaves taciturn and always uses a laptop alone as Shinkuro is apparently her sole friend, however Shinkuro only knows her true persona because of her habitual behavior.

Ginko seems to fall in love with Shinkuro, but willing to care him less than Murasaki and Yuno. But when Shinkuto says "I love you." to Ginko, she replies "Me too." to him, not such as their habitual conversations, as Ginko is the only one who knows Shinkuro's past, as she is really sincere to Shinkuro.

In childhood, she dreamed of marrying Shinkuro as well as undertaking Fuumitei, the ramen restaurant run by parents.

Ginko's advice is considered as her duty as she severely imparts Shinkuro but meanwhile treats earnestly.

Although Ginko supports Shinkuro as an informant, she strongly withstands Shinkuro to practice the troubleshooting, as she still remains in this thought. Therefore, when he is distressed on mediating troubles, she endorses him to withdraw from troubleshooting and undertake business in Fuumitei.

When Shinkuro attended to Seiryo High, Shinkuro had bought her a breakfast.

She sarcastically scoffed Shinkuro in which he is yearned by Murasaki as a pedophile.

She actually husbands a mug which was brought by Shinkuro.

In manga, her affecntion to Shinkuro seems more vivid than the novel.
