No matter where she goes, Sora takes her sketchbook along. The world is full of beautiful things, and Sora doesn't want to miss a single one. However, Sora is incredibly shy. She only has a few friends, but each one adds a new color to her world.

Today, Sora decides to leave the house starting with her left foot instead of her right. She's about to learn that little choices can lead to big changes! Meanwhile, Miss Kasugano has a new Secret Weapon, and it should be arriving any minute now...

It's the day of the Town Festival, which means music and fireworks! Sora will be going with her friends, and so will her brother Ao. But Ao knows how strange his sister is. He can't help but wonder... Is she always like that, even around other people?

This was supposed to be the day of the big Art Club Sketching Event, until the forecast called for rain. But two students still showed up: Nagisa, the girl who's obsessed with nature; and Sora, who never misses a chance to sketch something new.

Miss Kasugano has made up her mind. The Art Club is going on an overnight trip! There's just one problem: they don't have any money. So at the end of summer, she loads the entire class up on a bus, and they take a field trip to... their own school?!

There's a new girl in class! Her name is Kate, and she's from Canada. Natsumi is chosen to teach her all about Japanese language and culture – but she has her work cut out for her, since the other students start telling Kate all sorts of bizarre fibs.

The Art Club is holding their Fall Sketching Event... but as usual, Miss Kasugano has no money, so they end up in the school's backyard. Some students are disappointed, some are enthusiastic, and some end up being chased around by a stray dog...

After a lively afternoon picnic surrounded by cherry trees in full bloom, Sora finds herself alone in an empty Art Club room. But even though no one is with her, she doesn't feel lonely. Taking brush in hand, Sora finally paints what's in her heart.
