It appears that Rollsheep's only daughter in Prism is Shiki because, compared to Pina, they interacted with each other on Twitter (Rollsheep retweeted Shiki's first voice post and commented under Shiki's artwork of Luto)
Rollsheep follows Pina because she followed them first. Other Prism members, who also followed Rollsheep, also got a follow from them
If I have to try and guess Pina's artist, my guess is Rosuuri
>YU liked their tweet around the time the Gen3 was first teased>The liked tweet mentions 'overlapping deadlines'. Could one of those deadlines be doing the Pina's design for Prism?>Sometime ago, YU asked the community for western anime artists, presumably to find someone who could design him a Gen3 agent. Rosuuri meets this criterion and was often suggested in the replies>Rosuuri also designed two members of Tsunderia, an agency with which Prism has very close ties
