Rin Shima

Rin is a fair-skinned girl with thigh-length dark-blue hair that is tied in a high bun with bangs hanging over her eyebrows, two hair strands framing her face on both sides, and purple eyes.

When camping, she wears brown boots and black leggings, a pinkish dress, and a green sweater underneath a plaid grey shawl. She usually keeps her hair in bun. Sometimes she also wears a white knit-cap and she has her hair loose. In one of the episodes, Ena Saitō tied her bun into a small teddy bear and a generic Japanese castle.

In school, she wears the typical female uniform (seifuku, 制服) and she has her hair loose.

Her height is approx. 144 cm, slightly shorter than Nadeshiko at 145 cm.

Rin is depicted as having a quiet and reserved personality; preferring to camp alone. Showing somewhat of an introvert characteristics, the exact opposite of her later best friend and fellow (apprentice) solo camper, Nadeshiko. However, she is actually a very caring and friendly girl, despite can be a worry wart. Rin is wanderlust and independent, traits that she earned from her parents and especially Grandfather. Despite her being socially inept at first, she eventually grew out of it and actively enjoy her time with her friends, although she retains her love for solo activity and independence. Rin is also not awkward for showing her emotions and also prone to comedic moments thus making her actually enjoyable and helpful to have around.

Rin is seen slowly opening up to Nadeshiko Kagamihara and the rest of the Outdoors Activities Club members. While she completely dejects the idea and showing clear discomfort of interacting with people other than Ena Saitó, she starts to become a lot more friendly and accepting towards the club. Eventually befriending the entire group, this culminates in Rin agreeing to participate in the club's end of the year camping trip.

Rin is already good friends with the Outdoors Activities Club, despite her and Ena are not members of the club, they often do activities together and even went camping together. This is shown as the girls already refer to each other with their first names instead of family names. Rin also cares very much about the well being of the group and even worries about them when they went camping. The club in return respect and admire her, even to the point they comically refer her as the club’s savior, after the group’s camp near Lake Yamanaka almost ended horribly.
