I still have to read the last volume, since it wasn´t published here yet, but I love this manga!!! It was so hard, every time I finished a volume I had to read the next one immediately!!!
It caught my attention, because the cover looked similar to fairy tail
but I would say, it is even better than fairy tail (so far at least...) because it is not thaaaat looong, the characters aren´t that BIG idiots and it is easy to follow the story! more than once I wished that it had an anime! It is indeed similar to fairy tail, but I actually prefer buster keel:
as I already said, it is not too long
I like the relationship between the main characters (blue-keel)
no new main characters are joining the team, it´s only the four of them,
and their relationship is actually evolving...
So, I love this manga, it is one of the very few action mangas I bought, since I prefer watching action animes than reading action mangas (since there´s no anime I have to read it...)
I really enjoyed it so far and I can´t wait for the next and final volume *^*
