Taiki no Kawa (a Touhou LW original) refers to great streams of air that carry water vapor. They mostly originate in the skies above tropical seas. It's the temperament of Okina Matara, the traveler who sought and eventually created paradise. Shooting stars inevitably come to a halt. Okina is only endowed with star temperament (strong against Moon Essence but weak to Sun Essence).

The ability of Okina Matara, who has almost reached the end (a Touhou LW original). Okina completely lost this ability due to a Lost Word. She is currently regaining it little by little, though not through restoring or replicating her old ability, but with a newly constructed original ability that formed a core to build upon. She has continued to travel across worlds to try and end the Lost Word Incident. Okina Matara is a secret god and a great sage who was involved in Gensokyo's founding. She and her two servants, Teireita and Nishita, come together to form one god. Okina's life prior to Gensokyo's founding is rife with mysteries, with the discovery of reliable history documents being long-awaited. However, according to somewhat untrustworthy documents, this world's Okina arrived to Gensokyo after an extremely long journey. There is no definitive source that describes in detail the formation of Gensokyo and the origins of those who reside there. For that reason, it's impossible to have a succinct discussion about those things. Or, to put it another way, the ambiguous and uncertain nature of those things makes it possible to talk endlessly about them. And when it comes to gods, or specifically, a secret god with multiple aspects of divinity and great authority, it's possible to discuss multiple possibilities at once using the uncertainty principle. This is like the reverse of Toyosatomimi no Miko's ability, which lets her listen to multiple discussions at once. However, the price of discussing so many possibilities would be that an unimaginable number of patterns would be produced. Said patterns would be the combination of all viable possibilities and would soon expand to form a giant structure that could well be called the ruins of all the world's memories. There's no guarantee that even the Land of the Back Door, the back garden of knowledge and fantasy, could contain such a structure. All things lost and forgotten end up in Gensokyo. Gensokyo is thus the final paradise and is exactly what Okina sought. However, an investigation into Gensokyo's existence shows that everything will someday arrive there since everything will one day inevitably be forgotten. So... is that the paradise that Okina envisioned? An endless wasteland where nothing but records and ruins remain. "I have no intention of becoming a grave keeper..." It was definitely the land they had been seeking, and it was unmistakably identical to where they'd started. Okina called out to her two wheels, Teireita and Nishita, "Let's go." They'd keep going, no matter how long it took. Ofan is the name of Okina's mobile throne, and its appearance is that of the Land of the Back Door reversed. Okina not only watches over all of Gensokyo from behind the scenes but on her long journey to Japan, also got to see the wider world. But she didn't get a two-dimensional snapshot of things like a human adventurer or explorer might. As a god, she accumulated awareness in a dimension beyond that of humans. She saw the extraordinarily complex history of human migration and the lineage of cultures.
