This is a little toy she crafted by herself. Although her main job is a civil engineering witch, due to the uniqueness of Spider Teacher, she also works part-time as a puppeteer.
This little puppet marionette is actually her class assignment completed in Spider Teacher's class.
It's not a high-level combat puppet, but a God-Inviting Puppet used to connect her will.
The only noteworthy aspect is that this puppet has a high degree of concealment; its skin and skeleton can isolate most surveillance, and even if a bigshot tries to forcefully spy, it would trigger the puppet's self-destruction.
This is Spider Teacher's family secret technique, originating from Lord Demon King, so its reliability is naturally unquestionable. Moreover, after Dorothy learned it, she pondered a bit and made a small modification.
