A Smile type 1st year, Shizuku is a calm student who loves theater. 
In M's songs, Shizuku will most likely take the role of Kotori, and in Aqours, she will usually be Hanamaru, though this is subject to singer preference on a song-by-song basis. This does not mean she needs to sound like either, only that she is likely to sing those lines.

NOTE: This project does not follow the continuity of PERFECT Dream Project. Shizuku is still considered a Seiran student, not Nijigasaki. The voice also does not need to particularly mimic her PDP voice.
