Battle at Shiranui Fortress is chapter ten of the Hinowa ga Yuku! manga.
Reaching Shiranui Fortress, Elder's Class are viewing the place that will become a battlefield. Akame ask Hinata's permission to do a scout while taking out any enemy behind the shadow since it was her specialty to do so. To put it simply, the Elder's Class now are separated into two squads for the war. Akame and Tobari works under Hinata's command while Suzumaru and Kumehachi works under Hisame's command.
Hisame's squad in the other hand is observing the field and Hisame want to strike with a chance he get. Meanwhile Hinata report to Kahei who currently massaging Maruge's head, asking permission to send Akame out for scout. Maruge permit them to go in condition Hisame must not be allowed to deploy.
Akame went out to scout and discover a Soukai's scout was pursued by Tenrou's ninja that attempt to capture him. Akame quickly intercepts and defeat them, leaving one alive for interrogation before going out to find more Tenrou's ninja.
Several days later, Tenrou's army arrived with number of 30,000. The number is sixty times larger than Soukai that only deploys 500 to Shiranui Fortress. Approaching the Shiranui Fortress to do a scout, Yomihime shoo Kyoukotsu off since he knew that her plan was one of Soukai's expectations.
Kyoukotsu approach the fort, demanding one-on-one duel and Buaku comes out from the fort to fight him. The duel was brief and ended up in defeat of Buaku. He continue to taunt Soukai and Tobari was held by Soukai's soldier due to her short-tempered. Maruge know that he plan to lure Soukai's soldier out. Suzumaru later volunteers himself to duel Kyoukotsu. Preparing himself, Suzumaru steps out to duel Kyoukotsu.
