Safu from No.6
Safu (voiced in Japanese by Kiyono Yasuno, and in English by Hilary Haag) is one of the semi-main characters of the anime No.6.
At the start of the series she is Shion‘s best (possibly only?) friend, and makes some romantically inclined advances at him, though it’s unclear if it’s meant to be pursuing an actual relationship, or if she just doesn’t want to be separated from him.
She ends up becoming a very key part of what’s happening with the city later on towards the end of the short series.
Safu has almost shoulder-length dark brown hair, and brown eyes, and in this particular outfit she has an off-white long sleeved turtleneck, black leggings, brown boots, a deep red skirt, and over top of that she wears a greyish-white winter coat, with a long pink tasselled scarf.
Nezumi from No.6
Nezumi is one of two main characters in the manga, anime, and light novel series, No.6, and is voiced in Japanese by Yoshimasa Hosoya, and in English by Kalob Martinez.
When we first see Nezumi, he’s 12 year old and very badly injured, and ends up breaking into Shion‘s house, where the latter offers to treat his wound, despite having just been threatened by him.
A few years later, he helps Shion escape from No.6 when he’s being brought to a correctional facility and brings him to his home in West Block, showing him the world outside of No.6, sharing classical literature and theater with him, and eventually developing feelings for him.
Nezumi has blue-toned black hair tied up in a ponytail, grey eyes, and he wears a light yellow long sleeve shirt, a black motorcycle jacket over top, beige cargo pants with a ripped leg, blackish brown combat boots, and a large cloak that he wears as a scarf.
Shion from No.6
Shion is one of two main characters in the manga, anime, and light novel series, No.6, and is voiced in Japanese by Yūki Kaji, and in English by Greg Ayres.
He grew up living in the idyllic society of No.6 as a genius level student until he was 12, when he helped a boy his age named Nezumi, who was a fugitive, to escape, which lead to him and his mother having to move to a lesser part of the city.
A few years later, Shion was arrested for suspected crimes against the city and was in the process of being taken to a correctional facility, until Nezumi shows up once more and rescues him, leading him out of the city entirely.
Shion has short, fluffy white hair, red eyes, and a pink scar wrapping around his body, while his primary outfit is a white button up shirt, a light blue cardigan, brown pants, and blackish brown loafers.
