Abstract

Unlucky from morning till night.
Argh! Forgot it! Got yelled at!
Everything goes wrong, no matter what.
Starting with being late, forgotten homework, silly mistakes, endless trouble, getting scowled at by the teacher, and then scolded by the principal—
"Of all days, why today?!" A truly worst day ever.

Picture book author Satoshin captures these raw childhood emotions with a sharp, rhythmic prose.
Short, punchy, repeating phrases give voice to every child's inner screams, creating an upbeat, fast-paced read-aloud rhythm.

The artwork is brought to life by world-renowned animator Koji Yamamura.
Dynamic compositions and expressive visuals amplify the protagonist's emotional roller coaster, unleashing waves of laughter and empathy with every page turn.

This isn't a book for preaching,
nor does it wrap up failures in a neat, tidy bow.
It's simply a best-ever picture book that lets kids laugh off their unluckiest days!

Dedicated to every child across the country thinking, "Today is just not my day."
By the final page, they'll surely whisper to themselves:

—Tomorrow will be okay.
A reassuring comforting companion for any down-and-out day!
