Cant really call this isekai as her previous life/experience seems to have minimal impact on story. Yuri thing is quite problematic when it comes to the fact that she is in royal family, fun to watch it unfold. MC still gets to collect a harem (kinda). First 6 episodes are awesome, after that it is so-so. Poor execution of kingdom politics ruins experience. Vampire thing being completely out of place does not help either.
Production quality is quite good, but battle scenes are often lacking in vfx, choreography or overall.
Second part of season really tanks in story quality. The change of MC motivation, that happens after confrontation in second half, feels out of place and out of character. It just feel like that it was intentionally set onto generic drama rails for more emotional and soapy plot developments.
