Kainanpuu (a Touhou LW original) refers to a sea breeze. This is an apt temperament for Tewi since the Hare of Inaba is said to have crossed the sea back to the mainland. Tewi is endowed with Wood Phase as a rabbit, and Star Essence because she is free-spirited. The strong and kind Wood Phase resists Water Phase, because water nourishes wood, but it is weak to Metal Phase, because metal carves wood. The diverse and uncooperative Star Essence resists the cooperative and indecisive Moon Essence, but it is weak to the charming and arrogant Sun Essence.

The ability of Tewi Inaba from the world of eternal night (a Touhou LW original). It is essentially the same as our version of Tewi's ability. However, this Tewi may be involved in prolonging the Eternal Night Incident. It isn't known whether Tewi is the same rabbit featured in the Hare of Inaba legend, but they seem to share a lot in common. The legend is about a rabbit tricking a group of "wani," and it's notable how there are several similar myths in other Asian cultures. While "wani" in modern-day Japanese means "crocodile" or "alligator," it's theorized that the "wani" in the legend refers to a large species of shark native to the region. However, some scholars disagree, stating that crocodilians could have lived in Japanese waters in the past, considering how many other ancient tales use "wani" in reference to crocodiles. The Hare of Inaba legend is also famous because it features the god Oonamuchi (another name for Lord Daikoku) and has the earliest depiction of medical treatment in Japan. After the events of this legend, Oonamuchi took the name Ookuninushi and set out on a journey with Sukunahikona to build the nation. They also established many more treatments and cures during their travels. Sukunahikona is the forefather of inchlings, presumably making him Shinmyoumaru's ancestor. Also, it's theorized that Lord Daikoku is a divine aspect of the Matara god, so perhaps Okina could shed more light on the subject. The Bamboo Forest of the Lost used to be called Takakusagun, which means "tall grass district." The story goes that this bamboo forest was swept away to Gensokyo by a catastrophic flood. And Tewi is said to be the oldest rabbit living there when this happened. Incidentally, the Hare of Inaba tale starts with the rabbit getting cast ashore on an island due to heavy flooding at Takakusagun. Despite all these similarities with the Hare of Inaba and her apparent age, Tewi still works under Eirin Yagokoro at Eientei and allows her colleague, Reisen Udongein Inaba, to act as her superior even if she doesn't always listen to her orders. Tewi also made a mutually beneficial deal with Eirin regarding the use of the bamboo forest, indicating that they consider each other equals irrespective of the complex hierarchal structure of Eientei. But what's most suspicious about Tewi is that she only ever refers to herself as an ordinary youkai rabbit despite all the evidence to the contrary.
