Gamaran: Shura (2018)

Blurb:
It’s been two years since the infamous Unabara Tournament, but things aren’t over for Iori Sengoku—in fact, he’s received a summons from the Tokugawa Shogunate. He’s to join in battle against the Shogunate’s top martial artists to determine the strongest of the lot. Not only that, he’s accompanied by the sword-crazy Ran Ichinose. No matter what, this is an adventure you won’t want to miss—the thrilling sequel to Gamaran!
