Is the injured boy Neville? I hope you have included info about how our favorite canonical characters fare in this world.

I can't believe Snape could bear having anyone live with him who has the same name as his torturer and attempted killer. No benefit of concealment would be worth it. It will bother me greatly enough, can't even imagine how bad it would be for him.

Albus can go burn!

Canis? I actually started writing a German fanfic on Wattpad where I invented a pure blooded family with the name Canis

Minerva would be very upset if Severus has to leave! And I know why. She is in luuuuuuuve with him️

Porting the Death Eaters to Mars? Hahahahahaha!

Yay! Nowadays we might be asking Elon Musk what he and his people found on Mars.

Great story!

Very good chapter, and Sirius is a very good big brother. I'm very happy that Severus is free of the Dark Mark-even in Japan, it must have been bothering him.

I'm glad that Severus and Minerva seem to be getting together. And I'm very glad that Sirius doesn't get the visions from his scar any more.

Good chapter. It's so sad to hear about all the trouble back in Britain, but I'm sure everyone is glad to be safe in Japan.

A somewhat scary chapter-it looks like something will have to be done about Britain, and maybe sooner than anybody expected. Poor Harry!

And if someone took 35 years off my life and I kept my memories, I'd be just fine, thank you.

I wonder if simple surgery would fix Harry's scar? So far that hasn't been tried. Though they do need the news from home, Harry's paying a high price for it.

Hope Minerva is all right!

Good chapter! I hope that Professor Ito can help Snape get rid of the Dark Mark.

Not sure why the whole Stone business is going on at Hogwarts, unless Albus is trying to run Longbottom through the whole mess.

Oh dear, poor Sirius! He had too much fun at the party and caught a cold, and I hope someone catches him!

Very good chapter! I'm glad that Minerva and Poppy will be able to visit during the summer.

Why isn't Albus going after the Dursleys, or doesn't he consider them responsible for 'Harry's' disappearance?

The Tanabata trees sound great! (and I noticed that you're using only "Sirius' instead of 'Harry' for our little hero, he's fully made the transition).
