ジャスティス

Justice is a popular dōjin artist who often sells tens of thousands doujin at a single event, though does not earn much money due to production costs and the low price he sells his dōjin for. He is a childhood friend of Najimi. He appears to be highly protective to Najimi, to the point of getting very annoyed when noticing any man getting close to her. (Source: Wikipedia)
