Satsuki Igarashi (いがらし 寒月, Igarashi Satsuki?, February 8, 1969 -) is a member of the all-female manga-creating team Clamp. Her duties in the team are Nanase Ohkawa's sounding board, and the character designer of Chobits and line artist for Tsubasa: Reservoir Chronicle.
Like the other members of Clamp, she changed her name from Igarashi Satsuki (五十嵐 さつき?) to Igarashi Satsuki (いがらし 寒月?) as part of their 15th Anniversary and to try a new moniker.
Her cousin is fellow manga artist, Yumiko Igarashi.
According to Clamp's The One I Love, Satsuki was bullied as a child in kindergarten by a group of boys. However, there was one boy who always stood up for her, and Satsuki developed a crush on him.
