Suo Pavlichenko (Japanese: 蘇芳・パブリチェンコ, Hepburn: Suō Paburichenko) is a fictional character introduced in the anime series Darker than Black: Gemini of the Meteor.

A young teenage girl, Suo is an upbeat Eurassian photographer who lives alongside her father while aiming to protect her twin brother, Shion, who is a Contractor, a human with supernatural powers.

However, reviews focused on the series were positive due to how Suo fit in the dark scenario properly thanks to her likable personality and developed an appealing relationship with Hei.

In the anime Darker than Black: Gemini of the Meteor, director Tensai Okamura considered diverging from the previous season which would lead to the creation of Suo.

Due to Okada's experience with shojo works, the series targeted a female demographic and she was put in charge of several episodes because Suo was the new protagonist.

Although her mother is afraid of seeing her daughter's replica, Hei still accepts for what she is, making her realize her own feelings which Mao finds interesting despite Contractors lacking emotions in general.

Later, it is revealed that she has been transported to an alternate world without Contractors (including her brother), where she can live a normal life, with no memory of her previous one as she wonders if she lost something important.

Early impressions from Darker than Black: Gemini of the Meteor led to the media to call Suo moe due to her innocent characterization.

[15] Screen Rant also listed Suo as the second best character from Darker than Black behind Hei due to her dynamic with the previous lead and growth across Gemini of the Meteor.

[19] My Reviewer found the action sequences involving Suo's weaponry appealing based on the way it is animated but still felt them to be out of place when compared with other powers seen across the series.

[22][23][24] An Active Anime reviewer said that the series retained most of the prequel's appealing features, including Hei and Suo's many problems and the buildup to an apocalyptic prophecy.

[26] UK Anime Network had mixed feelings about the closure given to Suo's role in Gemini of the Meteor but better developed in contrast to Hei's own story that leaves the series on a cliffhanger.

[3] JT Online commented that Hanazawa's work was appealing as she "really brings out the emotion and pain out of Suou quite effectively" to the point of referring to her as one of the best Japanese voice actress behind the series.
