In this guide, you’ll learn how to get to Sadatame and move through the mission in order to be as efficient as possible.
The Bad Brother Overview – Assassin’s Creed Shadows
The Bad Brother is the first quest leading to the downfall of Ise Sadaoki. This mission directs you to his brother, Ise Sadatame, who may have valuable information about Sadaoki’s whereabouts. Sadatame can be found at a temple in Yamashiro.
Clues about Ise Sadatame’s location:
- He is in Yamashiro.
- He is north of Ogura Pond.
- He is at Byodoin Temple.
Finding Byodoin Temple in Yamashiro


To locate the temple, open your map and find Yamashiro, a region situated north of Izumi Settsu and east of Harima.
- Zoom in on Yamashiro to spot Ogura Pond in the southeastern part of the region.
- Byodoin Temple is located north of Ogura Pond.
- You can send a scout to the marked area for assistance. If no scouts are available, manually navigate to the location.
- While in the area, consider visiting the nearby viewpoint to unlock fast travel.
Meeting Ise Sadatame
Once you arrive, Byodoin Temple will still be an undiscovered location. Set a marker and travel there.
- Enter the temple through the main entrance.
- Look to your left—you’ll find Ise Sadatame sitting above the steps next to another villager.
- Approach him and initiate a conversation.
A cutscene will follow, where Sadatame reveals that his brother, Sadaoki, poisoned him and seized control of their clan. During the conversation, he will ask if you support Lord Mitsuhide. You can respond with:
- “I supported Lord Nobunaga” (Yasuke’s response).
- “I do not support Mitsuhide” (Naoe’s response).
Your choice only affects who delivers the line; it does not change the course of the mission.
Despite Sadaoki’s betrayal, Sadatame hoped to reason with him and had sent a letter. However, the messenger was attacked, and Sadaoki’s response was stolen.
Sadatame requests your help in retrieving the missing letter to verify his claims. Additionally, he asks you to recruit his ally, Ujimasa, who can assist in infiltrating Yamazaki Castle to confront Sadaoki.
Before the cutscene ends, you’ll choose whether to continue playing as Yasuke or Naoe. This choice is flexible, as you can switch characters later.
