Chapter 1Gourai is activated for the first time by Yamada and fawned over by Toda-chan. Hresvelgr spots her after defeating Stylet and challenges her to a quick duel.
Chapter 2Hresvelgr delivers a swift Curb-Stomp Battle to Gourai, then falls asleep from low battery exhaustion. Gourai makes friends with Stylet.
Chapter 3Stylet drags Gourai over to meet Baselard and the three have a sleepover. Baselard spooks Stylet with a ghost story and stealthily plants a sticker on her jetpack which is not discovered until the next day.
Chapter 4Baselard invites Stylet and Gourai over and they team up to build one of Baselard's beam rifles from its plamo kit runners, doing better than Fujisaki anticipated. The Materia Sisters spy on them and make plans to play with them.
Chapter 5Gourai is granted more freedom to explore the lab floor. She encounters the Materia Twins for the first time, and they are immediately taken with her cuteness. The Chapter ends with a meeting where the researchers are told to take their developments to the next level, while the Twins looks like they plan to enjoy recharging Stylet and Baselard.
Chapter 6Stylet begins the chapter recounting to Gourai how she did not appreciate the charging session the Materia Twins gave her, while Baselard is surprisingly unruffled. Gourai returns to the lab, where Yamada activates Jinrai, whose rather hammy and chuuni nature makes her reflect that maybe Toda's suggestions for the new girl's baseline personality were a bit much. Jinrai proceeds to get hooked onto Samurai Drama shows on TV, Baselard shows off her little castle made of stationery and boxes and candy, and Hresvelgr is demonstrated to be naughty enough that unlike the other girls she has not being granted permission to explore the lab more freely.
Chapter 7Baselard and Stylet spend time with Architect in the VR systems. Architect is shown to have grown from the Admin-level AI that governs the Factory Advance Lab, as the original AI was outfitted with an early version of the AS-style AI heuristics then granted the full mental presence of the FA Girl systems after the Materia twins were created. Baselard develops a fond friendship with Architect and eventually lets the researchers know that Architect was getting lonely inside the mainframe without a body of her own, eventually spurring them to give her a body.
Meanwhile Hresvelgr's developer manages to get permission for access to what can only be either the Ater or Rufus nanomachine augment(s) to upgrade Hres.
Chapter 8The girls take part in a small in-house tournament held by the researchers. Baselard resorts to trickery and cheesy tactics, like tricking Gourai into stepping out of the ring and getting disqualified for a ring-out, and showering Stylet with stickers. Jinrai ultimately wins due to her frustration at not facing serious opponents all the way until the finals, as Architect accidentally got herself disqualified for cheating with her Admin-level powers to spawn a sheep plushie as an airbag, and the Materia sisters deliberately throw the match due to disinterest in fighting.
Her prize? A cute dress made by Fujisaki. It turns out the Materia sisters rigged the draft order for the match-ups in order to manipulate Jinrai into winning.
