Negi Haruba debuted in 2013 with the story Coward's Crossword in Kodansha's Magazine Special. Haruba's first series was Purgatory Karma in 2014, followed in 2017 by Quintessetial Quintuplets, which is the artist's first manga to be published in English.
Stands out from other harem manga because the girls have a very genuine bond with each other as sisters, and everyone's dynamic with the protagonist is balanced and interesting...the art is very consistent and appealing and the girls are very cute! Recommended. -Women Write About Comics
