I find it interesting, there's a big mystery about why the game in the "real world" is being affected by what Elrise does in the "game world" and it's a newer way of showing to the MC how their actions have changed the outcome of their new world. Personally, I've always been rather curious about whether or not the actions a person Isekaied into a game has any affect on what players see on Earth 🤔
There is no mystery
The answer is the author thought it would be funny
And the justification is gonna be some magic god bullshit where one world is bleeding into the other or whatever kind of generic shit they pulled out of their ass
Answering this "mystery" is a complete waste of time
Japanese and general amateur writers are obsessed with trying to explain their premise
Im sure you think you got a very cool explanation but nobody gives a fuck, itdoesnt enrich the story in any way
As if anybody needed to know how and why mega jesus created magic in every shitty little E grade isekai
