Following the advice of Machina's friend, Takahashi, Veltol begins streaming games with a face reveal; he spends his days establishing his image as a streamer, using Takahashi's strategy and influence.

Veltol is asked to work as Takahashi's bodyguard; hoping to test the strength of his restored faith as well, Veltol plans to launch a surprise attack on the yakuza; but their run-of-the-mill heist leads to unexpected developments.
