Katen Gecchi (a Touhou LW original) refers to nights when the Moon shines down on beautiful flowers. This is Benben's temperament as a futuristic tsukumogami who gained a new body after multiple reincarnations. Raiko's magic helped reform her temperament by allowing controlled reincarnations into other tools. This temperament is specialized to resist Moon Essence and Star Essence.

The ability of Benben Tsukumo, the device driver (a Touhou LW original). Benben's original ability became this one when it was concealed by the system of the Capital. However, due to miscellaneous adjustments and the construction of alternate functions, Benben's musical capabilities are unchanged. This world's Benben seems to be a new type of tsukumogami... a tsukumogami of the future. This was achieved through reincarnation. If tools are cast aside without being laid to rest with a proper memorial service, they become tsukumogami. This implies that inanimate objects can also reincarnate. Some Buddhist sects also share this belief. They teach that all things, including plants and the land itself, have Buddha-nature and can thus attain enlightenment. That's also why so many youkai are named after Buddhist monks, such as mikoshi nyuudou (lit. foreseeing monk) and hitotsume-kozou (lit. one-eyed monk in training). Tools function thanks to the magic power of those who wield them. All humans possess at least a modicum of magic, and well-used tools feel like an extension of one's body because this magic has permeated through them. When old tools are given a memorial service, they are broken and made unusable to free this magic. If this isn't done, they might become tsukumogami. However, since tsukumogami retain the body of a tool, they cannot live forever and will eventually break anyway, releasing the magic inside them. The original tool is essentially reincarnated when this magic is then imbued within another tool. This world's Tsukumo sisters have continued to reincarnate over many years until, one day, their magic wound up in devices created by Alice the Puppeteer. They were highly sophisticated electronic devices that, for some reason, fell out of use in the Capital. Since they were essentially abandoned tools, they made the perfect home for the tsukumogami. With their power as tsukumogami, Benben and Yatsuhashi are able to create sound waves without having to rely on physical audio equipment that has already been set up. This allows them and the Prismriver sisters to perform in places that wouldn't otherwise be possible, greatly increasing the scope of their operations. Xanadu holds a special place in Benben's heart because it reminds her of the paradise she used to live in―the paradise she had all but forgotten.
