After chapter 119, explainers argue Magatsumi copies Ariu Mikaboshi’s insect sorcery. The chapters have not confirmed that. After 130, Reddit and MangaDex argue the first Enchanted Blade is Magatsumi, Tobimune, Kumeyuri, or Subaru’s unnamed sword. Jump has not printed a name. YouTube still bets cour 1 ends at chapter 60’s elevator. Cypic has not said so.
How this archive treats a camp
A theory can live here if it is labeled. It cannot migrate onto a character page as biography. The first-blade page is the kiln warning. The anime page keeps the elevator as a camp. If you want the printed insect kit, read Magatsumi and Ariu as two files. See YouTube room, Reddit room, first blade.
