Shogi Unrivaled in Another World: Reincarnated as a Prince in a World Where Wars Are Fought with Shogi, I’ll Save the Weak Human Race

After years of being ground down by an exploitative company, a man's mental health collapses and he loses all sense of purpose. Even shogi, the one hobby he truly loved, can no longer bring him joy. Eventually, he chooses to end his life. But when he opens his eyes again, he finds himself reborn as Yuri, a prince of humanity in another world. And this world has one very unusual rule. Every conflict is settled through shogi. Territorial disputes, political struggles and even wars between races aren't decided by armies slaughtering one another on battlefields. Victory and defeat are determined across a shogi board. For humanity, that's a serious problem. Humans are a weak and declining race surrounded by powerful rivals, and their position in this strange world is increasingly precarious. But Yuri possesses something nobody here could possibly have anticipated: the experience and passion for shogi carried over from his previous life. The game that couldn't save him from despair in Japan has become his greatest weapon in his new life. Now, as a prince of humanity, Yuri begins studying the unfamiliar strategies and customs that have developed around this world's version of shogi. Every match can determine the fate of lives, territory and entire nations, and the opponents standing across the board aren't merely playing for pride. Given a second chance at life and a world where his one true passion can actually change history, Yuri sets out to turn humanity's fortunes around one move at a time. An isekai reincarnation fantasy where wars aren't won with legendary swords or cheat magic, but by finding the strongest move on the shogi board.
