Armed Summoner――Otherworldly Rampage with the Black Spear――(Retitled)

Passing through the gate, that place was another world――. Kamiya Setsuna (神矢刹那) was just an ordinary high school student. However, by a strange turn of events, Setsuna, who was summoned to the otherworld of Ilse Vale, becomes caught up in the midst of an unprecedented Sengoku period of chaos and warfare. Having awakened to Armed Summoning Arts and becoming a wielder of the black spear, Setsuna, through encounters with the Armed Summoner Faria and Leongand, the young king of the minor nation Gandia, throws himself into battle. Unaware that beyond countless battles, various meetings and partings await him. Completed. On April 30, 2024, the subtitle was changed from "Black Spear and the Otherworldly Hero" to "Black Spear's Otherworldly Unrivaled."
