Thread Magic: Amane uses this form of magic to generate and manipulate thread. He often uses it to mend and alter clothing for his squadmates.
Thread Magic: Dancing Doll 「糸魔法『踊り人形』 Ito Mahō "Odori Ningyō"」: With an open grimoire, the user wraps threads around the target's wrists and ankles and forces them to move as the user wishes.
Red Thread of Fate 「運命の赤い糸 Unmei no Akai Ito」: With an open grimoire, the user creates a cat from red thread. By simply touching a target, the cat can change the outcome of an event to something more favorable for the user. However, the cat only protects those about whom the user cares. Because it is made of thread, the cat can unravel to propel itself quickly and to dodge incoming attacks. The spell drains a large amount of magic power as long as it is active.
