The sole survivor of an Ittry massacre at Anotsus hand and heir to her fathers sword school the Mutenichiry. She has mediocre swordsmanship skills but an intense desire to avenge the brutal death of her family. To aid in this quest she hires Manji as a bodyguard. It is worth noting that she kisses a sleeping Manji in the fourteenth volume and has shown on numerous occasions that she develops feelings towards him. They are as of now largely unreciprocated. At the beginning of the series she is portrayed as somebody who is trying to act mature but is still very childish as the series progresses she steadily grows up and loses much of her naivety. Rin is constantly torn by doubt over the righteousness and validity of her mission and fears becoming a hypocrite as Anotsu claims that she is more like the Ittry especially when he remarks that she chose to use throwing knives instead of a sword like the Mutenichiry teaches. Rin has three weapons a Chinese sword named Kutoneshirika which she carries in a Toju purselike scabbard of sorts a Tant type dagger and a set of small throwing daggers named Ogunchu Golden Wasps. Even though she is only mediocre in terms of fighting ability Rin is still more skilled with weapons than most women of that time period and the fact that she carries a small arsenal of weapons with her makes her somewhat unique.
