Herencia games get shared usually with a couple of months delay, I had hopes that this game would be an exception though. The only way to get it for now is to get mikocon vip account.
Sorry to bring in the news, but this one just got updated again not too long ago. I'm not terribly interested in the game, so feel free to take your time to update it. 敗戦隷姫エルネア to v25.04.23
