Games and performers
Runa Mizutani is credited as a member of NanosizeMir and participated in singing the in-show song for "REFLECTION BLUE." The composer and arranger of this song is Ryo Shuigetsu, so all music production cannot be attributed to NanosizeMir just because the singer's group affiliation is the same.
Inclusion location
The September 2020 three-track single album placed this song on track 3 and the instrumental track on track 6. In December of the same year, the 14th track of the RB soundtrack also included 'Summer Hourglass,' but the catalog did not assign a Game Size mark to this track.
Different responsibilities within the same project
The three tracks on the album are performed by Mummi Suzuki, YURiKA, and Runa Mizutani, all with lyrics by Kai, but with different arrangement arrangements. When organizing song information, the credits for each track are clearer than sharing a single author list for the entire album.
