She had to mail bomb him with several super computers to win?
Oof. And him just a newborn that doesn't even know how to use his abilities yet.
Edit: Just realized that I called the ai a couple chapters ago, lol. Though apparently his abilities are merging together. Toy only made inanimate objects animate, as far as we know. It didn't actually bring them to 'life'. And the shikigami imbues an artificial spirit into an object to give it the semblance of life.
So he just used both together to the nth degree and created actual intelligence. Let's keep him away from demon summoning, shall we?
