About
This is Idiom Academy.
As the name suggests, this school is home to human personifications of four-character idioms. While ordinary humans attend as well, the personified idioms are in the majority. Naturally, the students of this school are full of personality.
The stubborn one who never wavers once decided: the personification of Reckless Abandon.
Action over words, doing it right now: the personification of Lightning Speed.
The overwhelming narcissist: the personification of Self-Praise.
The lethargic center of the world (self-proclaimed): the personification of Self-Importance.
The history-geek old man (or so he seems): the personification of Learning from the Past.
This is the story of them and you.
