Counter's Magic takes place in a dungeon, and lives there is the host and teacher Ms. Nachtbauer.
With a cinematic, medieval and dark fantasy theme, she teaches individuals the old-school numerals, and her own invention, the Nachtbauer-style numerals.
Compared to the former, the latter has extraordinary details with swirls, loops, and overall abstract appearances.
Suddenly, after she designs the visual references succeeding the Nachtbauer-style numerals, a random set of uninvited intruders would break in to the dungeon, and Ms. Nachtbauer would confront them prior to her warnings.
When the intruders try to put her in imminent danger, she uses the mana stored inside her ginormous belly to hurl them with ultimate powers intact.
NOTE: The only individuals the series is geared towards are adults, not children.
