@havelmom Good thinking, except for the small detail that your wrong.
This isn’t a spinoff, it´s a remake. ONE creates the storyline while Murata draws the manga.
It´s the same thing that happens with web novels and light novels. After a studio picks it up, the light novel becomes the new cannon material while the web novel is either abandoned or updated super irregularly.
If we follow your logic, it’s the web comic that should change it´s name, since the webcomic is just a rough draft.
