The Spread Shot of Nitori Kawashiro from the world delirious with cheer (a Touhou LW original). She attacks with her Kappa Heavy Industries water-cooled weapons. Genso-Rigs, also known as fantasy machines or phantasm machines, were first invented by Nitori and later became a Gensokyo-wide hobby, with various people building and piloting their own rigs. The pilots are also sometimes called Genso-Riggers, jockeys, or cheerleaders. The rigs are powered by the pilot's cheer energy, so they can't move about on their own... at least, they shouldn't be able to.

The Focus Shot of Nitori Kawashiro from the world delirious with cheer (a Touhou LW original). She attacks with her Kappa Heavy Industries prototype close-combat weapons. Genso-Rigs were designed to have a somewhat human-like shape to make them more effective as vessels for magical power. This was originally Hina's idea, and Nitori is especially proud of Hina's Genso-Rig that they made together. Hina is actually the co-manager of Kappa Heavy Industries, the Genso-Rig manufacturing company founded by Nitori. Their motto is clean engineering, and they take special care to avoid polluting the river.

A Spell Shot of Nitori Kawashiro from the world delirious with cheer (a Touhou LW original). She pilots her Genso-Rig in this attack. Genso-Rigs are mostly made out of a material called doll-dough. The discovery of seemingly limitless deposits of doll-dough completely changed how battles of bullets were conducted in this world. However, since these deposits are located near the Rainbow Dragon Cave (though some deny this), ownership over them is highly contested by a certain god and other powerful individuals on the mountain. Kappa Heavy Industries try to keep it a secret, but they actually have to pay to access them.

A Spell Shot of Nitori Kawashiro from the world delirious with cheer (a Touhou LW original). She pilots her Genso-Rig in this attack. According to Nitori, her Genso-Rig doesn't have any cool, unique gimmicks, even though most Genso-Rigs do. Some combine into bigger rigs, have interchangeable armaments, or launch bits of themselves as missiles. Nitori thinks stuff like that is superfluous. However, she gets lots of requests for them, so she adds them begrudgingly. Fortunately, designing them can be fun. She also kind of thinks that the rigs look better unpainted.

The Last Word of Nitori Kawashiro from the world delirious with cheer (a Touhou LW original). She displays the true capabilities of her Genso-Rig in this attack. Agremlin's model designation is YKPMM-040. The Y stands for Prototype, K for Kappa Heavy Industries, PM for Phantasm Machine, and M for Marine and Land Deployment. The 040 is Nitori's identification number. Nitori acts as Agremlin's core, providing cheer (a fundamental temperament of the universe) to power its magical engine. More cheer equals more power, so Nitori wears a cheerleader outfit while she pilots it. Being an older model, Agremlin doesn't really have any unique features or gimmicks. However, this also makes it more reliable, and with its above-average specs across the board, it is rated very highly among the kappa. Agremlin has many weapons. Bullet shooters are installed in the palms of its forelimbs, allowing it to shoot not only lasers, but all kinds of bullets. The end of each limb is also equipped with a Vice Paddle―extra-tough claws that can be used in close-quarters combat. An orange jetpack is attached to the back of the rig, and behind that is Nitori's trump card: a devastating pair of massive single-use photon torpedoes. Although it has been stated that Agremlin has no gimmicks, a strange phenomenon occurs when these torpedoes are fired. The overflowing cheer energy gathers in Nitori's eyes. The Genso-Rigs might use mysterious technology that hasn't been made public...
