Diamond is Unbreakable - Chapter 151 
Rohan has managed to cross the street, despite Cheap Trick on his back. Triumphant, Rohan plans to repeat the same steps at every intersection until he reaches the Morioh Grand Hotel. Now in a lone alleyway. Rohan and Cheap Trick see a dog, and Cheap Tricks asks if Heaven's Door works on animals.
Cheap Trick understands that animals are subject to the same power, and makes all the cats and dog in the vicinity surround Rohan by pretending that Rohan is cruel to animals. All of them attack Rohan, overwhelming Heaven's Door. Suddenly, one of the dogs sinks into the ground and Koichi appears with Echoes ACT 3 and shoos the animals away.
Koichi explains that he's seen Rohan acting weird in the streets, and convinced that it wasn't a prank, intervened to save him. The mangaka is then moved by Koichi's thoroughness. Echoes uses its power on Cheap Trick, causing it to fall, but it clings to Rohan's back via its power, meaning Rohan's back will be ripped off as well.
