for the fifth ending you need to offer to trade to first doll seller on the route where you are trying to buy a code for zu. then when the option ''i have a friend in the hospital'' comes , pick 'nevermind' you will unlock the ending
for the ninth one , on the call zivil route when the android lady comes to take you with her , pick the first option ''i will get rid of her''
thats it
also can you help me with the 6th [dream ending] , 8th [i dunnooo friendd] , and 12th ending? i need help unlocking them i have read all other endings
for the sixth, change your name "Anna's child".choose all the options adding Zu-points(avoid losing it as well). pick "call Marci(or Tiller)" and "get the code from the seller"then you can get ending6
for the eighth,after the option "help Anna's children to get the code",when you meet the second android,pick "i guess we'll trade".this leads to ending8
for the twelfth,you just need to pick all options that add MC-points(avoid losing)and follow the guide(the"after calling Tiller/Marci"one),then you can get ending12
the above is how i get these endings.hope this helps!
