have they found the imai siblings? is this incomplete??

Nahhh, unfortunately, this is an open ending. I’ve been waiting for years if the author would like to draw a sequel but nope

They cant break the rules of time so they wont be able to stay in one timeperiod/world for long. They did meet up with them briefly again according to the photos the author dropped in like a photobook or special update but thats it they couldnt stay long

I just finish reading it. HUHUHU THIS HEALED SO MUCH OF MY CHILDHOOD
