Rejection is a mission in Ōkami, taking place in Taka Pass. Amaterasu and Issun managed to access Sasa Sanctuary, but where stopped from actually entering the inn. They met with Jamba and his Sparrow Clan underlings, but were told by the latter that access was prohibited while Jamba's daughter, Chun, was still missing.
Walkthrough
Although there is little information as to Chun's whereabouts, exploring Taka Pass will mean you inevitably have met Mrs. Cutter, who is seemingly hostile for no reason. Completing "Canine Warrior hunt" will also trigger the return of Mr. Cutter, who casually mentions capturing a sparrow. You can also freely talk with Mrs. Cutter inside the house, who mentions that being exposed to moonlight reveals their true form.
Now, if you explored the exterior of the house you will have noticed a falling wooden beam that you can use to access the Cutters' rooftop, where Issun will point out a suspicious patch, which you can blow open with Cherry Bomb. Do so, and wait till nighttime to return to the house, and enter it to drag Mrs. Cutter into the ray of moonlight shining through the hole in the roof. This will enrage her and her husband, causing them to fight you in their true form as Crow Tengu.
Crow tengu act as a mix between Dead Fish and Red Imps, preferring to fly around and throw fans, forcing you to use Power Slash to knock them down to the ground. Once grounded they will freeze in place, using their katana to block all your frontal melee attacks, but this in turn opens them up for another Power Slash as a counter, leaving them fully exposed and easily dispatched with a string of combos.
Chun will be revealed after they are finished, which forces you to return to the Sanctuary and finish the mission. Once done you can continue with the "Remaining Warriors" mission, but also explore the location for animals to feed, and head up the elevator to grab the contents from Jamba's treasure chests.
