Im guesing the left one is tsukiko => you need to check the suspicious bunny when going with izanami in the festival (afternoon)
As of for the right one i guess its maeve => it will unlock after doing the main quest that requires to complete the 7 main girl prologue event (asmedia, heramael, estia, cleo, izanami, tsukiko, sheila)
