Seishin Gakuen Shogi Club (清正学園将棋部) is a single-player Shogi (Japanese chess) game. Everything runs on the device; the app never goes online. <b>Features</b> * <b>Complete Shogi rules</b> — check, nifu (double pawn), uchifuzume (pawn-drop mate), sennichite (repetition, including the perpetual-check loss) and nyuugyoku (entering-king, 27-point rule). * <b>Offline AI</b> — an AlphaZero-style policy + value network (Bonanza-method trained) runs on-device through a single-threaded PUCT MCTS. Eight strength levels. * <b>Eight opponents</b> — club members and teachers from Lv 1 to Lv 8, each with a portrait and a short bio. * <b>Teacher mode</b> — tap "Ask Kato-sensei!" during a game to see the top three candidate moves with win rates. You still choose the move yourself. * <b>Play experience</b> — multi-step undo, resign, last-move highlight, piece and UI sounds, haptics, save and resume. * <b>Kifu save and review</b> — export games as .kif, then replay and analyse them from the title screen. Every move is evaluated by MCTS and tagged ◎ good / △ dubious / × blunder, with a recommended move for blunders. * <b>Board</b> — kaya-style wood grain, traditional pentagonal pieces, brush-script piece kanji (Fude Goshirae). The user interface is in Japanese. <b>Privacy</b> No network permission. No ads, tracking or analytics. The AI model runs locally. <b>License</b> GPL-3.0-or-later.
