Kurogane was a manga that I chanced upon. I think it really is a shame that it isn’t very popular, as it contains many of the elements of a successful sports manga.
I really, really enjoyed reading this manga. It got me excited to see what would happen, and much like Haikyu! or Kuroko no Basket, the prospects of strong opponents, developing friendships and skills added to the story. The integration of a supernatural element was unusual, but I thoroughly enjoyed it.
There aren’t many drawbacks to Kurogane but the main one I would like to point out is the length. Because it is so short, I really hoped to feel satisfied at the end. The character development could have been more in depth if it were longer, but in the end, I really loved reading it.
