sorcerer's sutra scroll

Hijiri Byakuren's magical accessory. It's a colorful scroll with sutras written on it, said to be able to chant them on its own. Only Byakuren is able to handle it.
The Symposium of Post-Mysticism said its official name is 魔人経巻 (Majin Kyoukan), but its common Japanese name is the Air Scroll (エア巻物) which came from one of her spell card.
