Takeshi leads a band of bandits camped in the snow of Sago in Kamiagata. Yuna once rode with him, and she sends Jin to recruit his archers for the attack on Fort Kaminodake in Wolves at the Gates.
Takeshi joins Jin at a woodcutters' camp above the fort and is stunned when Jin climbs a wall with his grappling hook in seconds. His archers shoot from a ridge while Jin fights below. You can cross the bridge loudly or sneak under it to destroy a hwacha.
He asks why Jin is not with Lord Shimura. You can lie and say Shimura sent you ahead, or admit you split. The truth makes him question your authority until you say Shimura will not need the fort before spring. He jokes that the Ghost was supposed to be ten feet tall.
