Art style
Ito stated that she enjoys drawing because "the first thing players are attracted to is the game's art". Many of these games take place in the emotionally charged world of high school and Ito draws from her own experiences. Although she has designed several very successful characters, Ito stated that she draws her inspiration from anything by which she comes. She described the midpoint between a young female and adult body where it resembles their male counterparts and simultaneously are on the cusp of becoming a full-fledged woman as being the form she likes the best and enjoys drawing the most. Ito stated that since all women have been high school girls at one point and enjoy reminiscing about those times, noting that "being a highschool girl is probably the best time in a girl's life."
