Conclusion ¥ The First and Last Big Brawl!!.Nagare proves to still be hostile, as his new evolved hero suit, Justice Dollar, is revealed to be the one causing the overwrite, with Adachi planning to use his negative energy to convert the world into data. Learning Justice Dollar is the one controlling Nagare, Mitsuo and Fukuta manage to gather the data for Long's virus and have Kaito infect Nagare's suit with it, leading him to get hit by his own attack. Nagare starts to come to his senses, realising the folly of his ways, but is suddenly possessed by Justice Dollar's backup system, leading to one final clash between Kaito and Nagare, ending in a double knockout which stops the overwrite. As the city reverts to normal, Adachi stays behind to let Kaito and the others escape the Underbank before it collapses in on itself. While Kaito and Nagare rekindle their friendship, another boy watches over them.
