"Tabitha & Tabetha Rensei" Done by my wonderful friend, PSI, thank you very much!
PSI has done a few concept-references of a few additional characters over time, so I thought it might be nice to post those pieces. Here we have Tabitha and Tabetha, better known as Bitty and Betty. Quiet and mysterious, they are Rini's best friends (friend?). Only Rini can distinguish between the two.
