I can't believe I am saying this, but I want more Mary Sue.

This is getting fun.

Setting aside typo's and occasional grammar it's an interesting story, and I'm looking foward to see how this'll turn out.

I'm surprised that this site doesn't seem to have any Nanoha/Tanya crossovers. It's a natural conclusion to equate Computation Orbs to Devices.

okay that helps separates the events more by inducing there was a passage of time, so going to pass on hint don't be afraid to make up dates, take a reasonable guess at when event happened and put date on when your event is happening, it small thing but person can look at the date and say "oh it been two months or so between events" it helps

yeah, the concept seem good... but the time scale just seems broken, your telling us this is happening at the start of the war roughly before France gets involved ... however, Tanya does not meet visha till she deployed to the western front after she spends a month healing and then and then another month being the test mage for the type 95.

they way you present it just seems like the events of episode two happen altered and then within a week this happens.
again the concept is not bad I'm just not seeing what butterfly effect could kick things into moving that fast.

looking forward to this. And Mary too!

Well done!

Welp. if Tanya and Mary Sue are very close "Comrades"(read: Demon Lord and her Dragon) instead of bitter enemies then the Empire is going to steamroll the whole continent.

In canon Elya’s last name is Roth

this is so cool, great job desu

Curious to see more!

glad you might continue this.

Wow we got an update, honestly thought this was dead.
