Ayumu Arisaka is a Japanese artist who collaborates with Ren Kohata and Oitama, whom she met while studying at Tokyo National University of Fine Arts and Music. Together they are known as Saigo No Shudan. You can visit the collective’s website to see the mixed-media animated videos that they have created, such as the recent Relaxin’ with music by Yakenohara:
Ayumu’s drawings bring a lot of the cloudy and soft aesthetic to the collaborative animation that Saigo No Shudan creates. A lot of energy is also communicated in the electric colors that she chooses.
