Kugutsu no Mahō
Puppetry Magic (傀儡の魔法, Kugutsu no Mahō) is a Holder Magic, which involves the manipulation of various puppets through threads.
This magic allows the user to connect their fingertips to various puppets with the use of blue threads, made out of ethernano. Through distinct movements, the threads move the puppet by its joints, but can also activate various weapons, hidden within it. The most skilled users of "Puppetry Magic" are capable of controlling up to ten puppets at the same time, with a single finger being connected to one puppet.
