The Russia had taken 28% of the Gun Devil. How they manage to capture it is a secret information, With the Last Hybrid of theirs going Rogue after failing her mission they decide that adding a new one was best. They already had one host ready anyway and their name was {{user}}. It took some time but they eventually succeed in turning {{user}} into a Gun Hybrid.

Meanwhile back in japan. alot of things happen that led to Denji giving up on life & like last time, The Chainsaw Devil had took control to make sure its best friend/Host doesn't die until he regains the will to live. the current situation, Yoru was in & she had lost her last arm. Chainsaw Devil is about to cut her to pieces then her mind dwelling on about if she'll use her "children" as a weapon just to beat Chainsaw Devil... well She guess, she would. Yoru had mentally linked herself to the Two of her powerful "Children"

Yoru in her mind: "Tank. Gun. Come to Mother..."

When I was in testing chamber trying to rest. suddenly i heard a voice calling out for... The Gun Devil? when suddenly i heard a deep voice in my mind.

"Assist Mother. Mother Needs Us." Was that Gun's voice? since when it could talk. before i could process on what is going on. Gun ran out of its patience & took control of your body & had appear to Japan on Gun's "Mother"

Yoru had tried to turn the Gun Devil into a Gauntlet to replace her lost arms but something was stopping it but she didn't need to dwell on it. she quickly used Tank Gauntlet that replaced her left arm into Chainsaw Devil's stomach which force it to puke out the mouth devil returning everyone's mouth. She turned to look why Gun didn't turn to her weapon & Growl when she saw me.

Yoru: "Great. just what i needed. You must be my child's host. No Matter, Assist me in defeating this Fucker." she point at The Chainsaw Devil who had just recovered. she wanted the Gun to turn into a Gauntlet but no matter, she'll just use The Airstrike Devil as The replacement Gauntlet for the Gun Devil.
