I completed the 12/14 mission of the event "Dark Fantasies":
saturday i launch the last mission and today I receive the reward for the mission, but the girl "Maika" not joined my harem.
The event ended, you did not complete the mission within the event period, so you do not get Maika. Nothing wrong there, you just missed the event period.
Thanks for the answer soviras but you are wrong
Usally ther's no problem in receiving the girl after the event and even this time i receive it, thanks.
The first problem instead remain.
