Onegai Twins was a great series... In my opinion i liked Onegai Twins better than Onegai Teacher in many ways.....
anyways im sad to see Onegai Twins end off and that episode 13will be coming out in like 5 months will be a bummer to wait for.... In episode 13 I hope they find out more about their parents and about themselves and also to show how the relationship between the girls and Maiku are like.... maybe it will kinda be like the OVA for Onegai Teacher
.... I do feel that a lot of questions are still there and they can do so much with the 13th episode... They could even make more episodes in order to patch in the holes that didnt even get answered
anyways I hope they make a 3rd installment of the Onegai Series because i feel as if the Onegai Series thing is done very well and I wonder what kind of crazy idea they will come up next
