2 Rika... i have seen in the cover of the consol ver 2 of her... and i have seen a purple haired girl in the anime... the 2 Rika could be the past and future her playing together by then... before one of them decided to get demoned away so that she can live in the other Rika... and the purple hair? could be Yashiro... orrrr this could all be non-cannon from consol ver and the fact they allowed some other failed writer to come and write new routes to this already hacked ge written by the biggest failed writer is quite funny @_@
