Please note that I will mention spoilers in this review.
This story starts with three thieves entering int competition to see who can steal the most precious thing from the city, And the first season plays out as a fairly typical Shonen, as our protagonist gets involved in trying to solve the crime and get revenge for his father.
But season two is a complete mess, with new sub plots being added every episode, characters doing things for poorly explained reasons and NOTHING getting resolved.
But surprisingly, the show's not all bad. The two main characters are very well written, The male protagonist doesn't follow the typical
Shonen tropes of going through a sudden improvement in skill. He starts out as slightly above average, and is all he is. And he doesn't attract the attention of the girl by rescuing her or by his skill, but by being considerate.
Overall, the show is watchable, if only for the characters. Sadly, it is probably one of the best Chinese anime currently out there.
