This anime concludes the Karan arc quite nicely. Honestly, it would have been perfectly fine if it had ended there, since the second half of the finale mainly serves as a tease for the next arc. If there's no plan for a second season, I would have preferred they not leave things hanging like that.

Overall, while I wouldn't call this anime a masterpiece or anything particularly outstanding, it was still entertaining, especially if you enjoy this kind of premise. I love the characters, and that helped keep me invested throughout the series. I don't know if a second season will happen, but if it does, I'll definitely be watching.
