Itsumo Pocket ni Chopin

And then solar system colonization, with magically aided spaceships. All the way up until she find her way back to earth and take over IT too.
And then she finds her original self and gets all existential and kickstarts a paradoxical wormhole that sucks the entire universe into it and creates a whole new universe, where everyone gets born twice at the same time from different mothers.
And upon realizing this, the two Astrids decide to have a lesbian relationship. Because that's pretty hot, if you think about it.

I really have grown to love the bulk release format. Sure, I have to wait longer to see what happens next, but it's not as painful because I feel satisfied.

we've got an adaption coming in April by P.A. works, wooo...!

Dr. Riddles and Kid's reunion is going to be really emotional for me. Their final scene together I was literally crying. Can't wait for him to start pulling his iconic gag on everyone.
