Stowing away weapon
Usually, the power of demons can be sealed inside a small object, which is easy to carry around. However, the stronger the destructive impulse of the demon, the bigger the blade of the weapon, even when sheathed. Since the demon weapons wielded by Yuu, Glenn and Kimizuki have a huge destructive power, they cannot shrink like other weapons.

Weapons with the power to cast blessings or curses can usually shrink. Shinoa's and Yoichi's weapons belong to this category.
