Harigane Service is a manga that has a potential to be a mainstream sports manga title. I love the character development of the protagonist Kanna and I also love how the story progress. The only downside that I have in this manga is the slow updates but nevertheless, this is the first time that I read a manga that focuses on the pinch server and the mangaka really did its best to highlight the protagonist's role. All in all, its a good read and I hope that everyone who like Haikyuu or other sports anime can give this manga a go :)
