nijiiro zakura

I feel like Koutaro (こうたろ) is one of those artists where you may not know the name, but you've definitely seen his work. If you tuned into the girls baseball anime Taishō Yakyū Musume last year, then you were looking at his adapted character designs. Operating under the circle name Nijiiro Zakura, Nijiiro Densho is the 5th colorful illustration book released in this series.
