no... I was whrigt from the start, this is bad as hell I saw one season and 5 episodes. I am not gonna tire you by mentioning what you can find in the official review.
The Good:
Lovely animations. Nice idea for story (magic and tech)
The OK:
It somehow manages to survive the harem tag, since there are some males B protagonists, but just barely since, nearly every girl is in owe by our awkward and (wanna be) socially distanced Main Character. There are some well written characters too. Tries to give personality to them all also.
The flow of the story I haven't decided if I consider it bad or ok, it is kind of giving the impression that there is order in the chaos, but I can't put my finger on it, so I leave it here.
The Bad:
I will start with simple bad things... Brother & Sister(are they?) romance and an awkward as hell one at that. So many characters that you lose track after 7 or 10 episodes. Over powered M.C. just for the heck of it I asume, since I haven't after all those episodes come to understand why.
AND my two biggest complaints... I saw over 30 episodes The story is a damn mess since sidestories interact with each other and then get out of the picture only to get back when the writer needs them. The M. C. alone has over 4 different occupations (student, bodyguard, magic mechanic, soldier, relations with high profile clan, ninja, you name it) and is not like the other characters are far back on that subject. We are talking about 15-16 year old people here may I remind you.
After over 30 Episodes I know NOTHING! I don't know how he became so strong, how he became so "weak", how he has the connections that he has, what are his connections, I have only a very abstract idea of how the magic that the whole show stand upon works, making it feel like the whole magic power is just broken and new spells get drown out the hero's hat every time is needed. The show tries to sell it as Sci Fi but no, is just magic, and a soft type (with little understanding) to say the least.
Conclusion:
I started and saw 5 episodes back in the day and didn't like (mostly because of the brother-sister relationship) I considered it a joke. Now that it started again I decided to give it a real chance since it would pop up in every recommendation... I feel I wasted nearly 10 hours of my life. I leave it with the only second thought that if it has a manga it might solve many of the story's issues. That's all from me.
