That's true, it us a mixture of different genres of anime and I liked that, I just gave the fact that it also has romance in it.
if you liked the way they met you should see the Progressive movies, they are based on the novel of the same name that tells the second floors of the castle one by one and does not give the abysmal jump of the anime where they go from the second floor to the 50th floor.
Yh, I've watched to next once, I just wanted to continue in the novel.
Thanks for the honest reply.
