After meeting up with Akechi Mitsuhide and his son-in-law in Assassin's Creed Shadows, they team up with Naoe to put an end to Oda Nobunaga, who's hinted at being the Horseman. While talking to Ise Sadaoki, he reveals the plan to Naoe and how she'll arrive inside the Honnoji Temple, concealed in a delivery cart, ahead of the attack. However, for this plan to succeed, players must find important papers allowing the cart to enter the temple, starting the Belly of the Beast quest in AC Shadows.
