I think I might as well drop this series. This is too ridiculous and far too forced. I'd still accept Salt-God Satou to do strange things, but Oshio is supposed to be a normal dude. Furthermore, this triangle drama just doesn't fit. I had no problem with Rinka having a crush on Oshio when the dude saved her from Truck-kun, but that's it and that's where it should have ended. It feels like the author simply doesn't know anymore how to proceed with the idea/theme of "Salt-God" and is just throwing the net left and right randomly, trying to see if anything sticks.
I don't regret reading this far, but this is enough.
