A Japanese publishing company has released a book that teaches chemistry with characters from Kagami Yoshimizu’s popular Lucky☆Star manga.
The 368-page book features over 100 illustrations of the manga characters, it’s meant for high schoolers to prepare for college entrance exams.
Not sure if it works for the students, but I can foresee the book being pretty popular with Lucky Star fans as a collector’s item. It might open a new wave of income source for the anime and manga industry lol.
