Is this an AU spin-off, a "future" thing, or an "age growth drug" set-up?

...Either way, it's awesome.

I don't think this a ''future thing'' this is most likely from the spin off novel that features Ikkyuu Tensai as the mc, the main novel isn't even finished.Considering that the relics have magical ability's maybe is one that have grown her up ,i doubt she will naturally will look like this some day lol btw what is a AU spin-off ?
