Where can I watch this? I hope its not Japan only. Some things online say it came out in 2025. Doesn't seem like its screening in the UKKK unfortunately…

Worst case you will have to wait until it is released on BD or streaming so that someone can rip it and put it on nyaa.
Why is every adaptation of this so different from the light novel? The manga was pretty close I guess.
Just wait for the torrent. Its still a new release in USA/Canada, so it might be some time before someone uploads a rip
