Okay so to start with, for me this is one of the more unique and memorable high school-harem and ecchi kind that i have watched, for me i loved the story and I think that the past lives memories idea was fresh and cool. The fight scenes were also plenty and were pretty good. For the main characters, -the main lead is the OP and kind type -his energetic and chirpy sister from his past live -his lover from another past live of whom he has saved from slavery To add on, the ost and soundtracks were simply epic. All in all, in my personal opinion this anime is definitelyworthwhile watching and i have enjoyed it a lot, I also think that the story has more potential and it can be developed further.
Btw this is my first review so bear with me please and this is purely my own personal opinion!!!
