Our Blood Oath by Kakazu Kazu is a fairly new shounen manga from Shounen Jump! As good as the story is though, it is only a oneshot. That's right, folks, this is also a short-lived manga series like Guardian of the Witch by Sakano Asahi and Time Paradox Ghostwriter by Ichima Kenji. They all have amazing stories that could very well keep going in a serial but unfortunately, they don't last.
