"As expected of the Hojo family's higher-ups..."
In the original timeline, this would have been an excellent way to divert trouble elsewhere:
They would hand the Heavenly Feather Robe to another capable faction-in the original story, Inuyasha's group-and let Kaguya, who wanted the Heavenly Feather Robe, fight the faction unwilling to let a demon take such a powerful treasure. Ideally, both sides would fight to the death.
At present, Mount Hakurei still stood.
It was undoubtedly the most suitable place to store it.
As long as the Sacred Barrier remained, demons and evil spirits could not enter Mount Hakurei at all. Once some powerful figure killed the contender for the Heavenly Feather Robe, the Hojo family could simply retrieve the treasure from Mount Hakurei. There was no hurry.
Either way, the benefits would stay in the family.
And this was precisely the main reason Kaguya had yet to revive completely and regain her true peak strength. The Heavenly Feather Robe was essential for her return to her prime. Moreover, once the treasure had been placed within Mount Hakurei's Sacred Barrier, the celestial maiden's ability to sense it had dropped to practically nothing.
