Mystic Sumatra Art—Glove Slip!
After familiarising himself with the Skill, Inala began to use it more and more until he didn't need a physical Glove Slip anymore.
Upon activation, a stream of Prana covered his hand, with absolutely zero influence from him, 'Prana in its purest form. So, that's the secret.'
It was the Prana present in a Parute Fruit, in its purest form, without any body, mind, and soul influence of a living being.
This unattributed Prana seeped into an Information Slip and spontaneously morphed into a form suitable to wield the material—forming the Information Slip—as a Spirit Weapon. basically, like water occupying the shape of its container, this unattributed Prana changed to suit the material.
Once it was done, it was as if the Prana was generated by an individual who could treat the respective Information Slip's mineral as a Spirit Weapon. This was the underlying principle behind the Glove Slip.
