I almost wish this was a paced release instead of dumping all of them at once, there's so much to comment for each chapter.
Every time Snow Halation was used was perfect and so is Nico necromancer.
Kotori bird referencing videogames had the best comedic timing.
And the story was lot better than all the other half-assed isekais that air every season, having the real villain be the passing of time is genius as well as having Kotori be the real protag.
Didn't expect the feels at the end, geez. The shiptease in this was great but the overall story was not something I expected to be this good. Probably one of the best fanwork I've seen. Now if it had proper Nicomaki, that'd be a different story entirely
