I designed the characters “Katacchi” and “Suzy” that appear in “Kadokawa’s Collecting Illustrated Book GET! Playable arithmetic” to be released by KADOKAWA on July 10, 2024.

Playable arithmetic is an illustrated book based on the concept of getting familiar with and falling in love with arithmetic before you know it. Katacchi and Susy appear in the magazine with cute illustrations and photos of “numbers” and “shapes,” and they think together and give you hints.
