Nitta's Splendid Day is the fifteenth chapter of Hinamatsuri manga series.
Plot[]
Nitta goes through a typical day in his life. He spends his morning completing paperwork and helping his fellow gang members complete their administrative tasks. While he pretends to be exasperated with having to help them so much, he secretly appreciates how integral he is to the organization and how he fills a managerial position. His boss takes notice of Nitta's efforts, and those in similar positions grow jealous of him. After finishing work, Nitta runs into Hitomi at the grocery store and they gossip about Hina. When he returns home, Nitta cooks dinner for himself and Hina, cleans up after her, and realizes his personal life is now pretty domesticated.
