Cheerful Child: Despite having a single facial expression, Renge is a very cheerful child who constantly makes up her own songs, gets up to the usual childish mischief, friendly and very approachable, always curious and always ready to play.
Cloud Cuckoolander: Her interests are quite different from the other girls. Hotaru, Komari and Natsumi thinks it's hard to communicate with her.
Cry Cute: In Episode 4, after hearing of Honoka's departure.
Meaningful Name: Renge is a pink wildflower, although she didn't know it herself.
Height Angst: Doesn't like it when people mentions her height.
Lethal Chef: Averted in the beginning, but her cooking gets progressively worse as the series continue. First she made onigiri normally. Then she forgot to put water in the rice to cook it. Then she tried to make a bento and burnt everything. Hotaru ate it anyway.
Annoying Younger Sibling: Natsumi would go out of her way to annoy her older siblings, particularly Komari, whom she frequently makes fun of because of her height and childish personality.
Book Dumb: Does very poorly in her studies, and had received her mother's wrath numerous times because of it.
Bratty Half-Pint: Was very prone to troublemaking even as a child. As her mother puts it:
"You were the world's biggest brat back then!!!"
Jerkass: A troublemaker who frequently plays cruel pranks on her siblings, defies her mother, and refuses to take responsibility for her mischief.
Never My Fault: Natsumi never sees herself to blame for whatever trouble she caused. She tore the paper screen at home? It's the door's fault for ripping so easily. She pulled off a roof tile? It's the tile's fault for coming off so easily. She got bad grades for her classes? It's the exams' fault for being so difficult. She overslept? Her sister's fault for not waking her up...
The Prankster: Frequently plays pranks on her siblings, such as wearing a creepy clown mask in the dark to scare Komari, or turning Suguru into a scarecrow while trying to avoid working in the fields.
A third-year middle schooler and Komari and Natsumi's older brother, Suguru is the only named male character. He rarely if ever speaks, but is responsible and good at sculpting with clay. He can also play the guitar.
The Comically Serious: He shows almost no reaction to some of the things Natsumi puts him through. Then there's his high speed getaway in episode 6.
Extreme Doormat: He willingly goes along with whatever antics Natsumi has in mind, such as turning him into a scarecrow during the "class field trip", or burying his head in the sand and forgetting about him in the Beach Episode.
Hidden Depths: Never speaks, has demonstrated the ability to make sales-worthy clay anime figurines and play the guitar.
Nice Guy: What other way is there to describe a guy who wins a free trip and instantly gives it to his sister/
The One Guy: He's the only male character introduced so far.
The Voiceless: He doesn't have any lines and isn't voiced in the anime. The one time he is seen speaking in episode 8, we can't hear his voice because he was playing the guitar.
The Reliable One: He quietly retrieved his sisters when they 'ran away', and helped Hotaru when she got lost while walking her dog.
The only teacher at Asahigaoka Branch School and Renge and Hikage's older sister. Kazuho can sleep any time, anywhere. She often sleeps in and arrives late to school for this reason. Her family owns a rice field.
Kaede runs the local candy store. Due to the shortage of children in town, she is perpetually short on cash and for this reason also rents skis, futons, etc. Kaede acts cool and calm, but is very kind and gets along great with Renge.
Shameless Self-Promoter: A very mild example, as the first thing she does upon coming home is to brag about studying in Tokyo and riding the bullet train. Before Hotaru reveals that not only did she grow up in Tokyo, but she took a plane to get to Asahigaoka.
Natsumi and Komari's friend who lives next door and attends the "local" high school as a third year student.
