Loli parade

Finally! A religion I can follow!
Where do I sign?

It seemingly random series that are together or is there some kind of connection?

I'm getting an Infinite Statos ED vibe from the Madoka characters.

It feels to me as it looks like a Parody of a Hyakki Yakō (Night Parade of One Hundred Demons) from Nurarihyon no Mago, but on much Loli-er than its original -w-

It would seem Hakase and Becky have swapped places, much to everyone's confusion.

What is this, the Ani-Main Street Electrical Parade?

According to roughly translated description on Pixiv, it's a Milky Way of randomly selected loli characters (probably some of artist's favourites) in a Tanabata-like Parade.
