The devil has a little water slide under his arm. He’s taking it back to Target to return it. He says it has too much water in it, and he’s not a fan of water.
Think of the absurdity of the situation. He also waits in line, despite being all that is evil. When he gets to the counter, he’s very polite about it, but gets mad when they say no returns, just store credit.
The water slide is about going and motion.
通る to go by
送る to send
And then we have anti 反 on a water slide about going?
Anti-going is returning.
Maybe though こいち is onto something. Jesus is likely involved and put all the water on the slide.
And it’s some religious prophecy about the second 返.
