Seibuen Amusement Park in Tokorozawa, Saitama is throwing a dual-world Halloween bash, blending the “this world” of Dekin no Mogura（出禁のモグラ） with the “afterlife” of Hozuki’s Coolheadedness（鬼灯の冷徹）. Running from September 12 to October 31, 2025, the park’s first post-renewal Halloween event packs a talk show, puzzle hunts, limited food and goods, festival games, and ride audio you can’t hear anywhere else.
