Tatsumaki (a Touhou LW original) refers to a tornado, which is a violently rotating thin column of air that extends from the earth to the clouds. This temperament embodies Hina's duty of collecting misfortune on the ground and delivering it up to the gods. Hina is endowed with Fire Phase, with her unending and relentless responsibility, and Moon Essence, as she is a being estranged from the daily life of humans. The formless and passionate Fire Phase resists Wood Phase, because wood feeds fire, but it is weak to Water Phase, because water dampens fire. The cooperative and indecisive Moon Essence resists the alluring and arrogant Sun Essence, but it is weak to the diverse and uncooperative Star Essence.

The flow of misfortune is an important cycle in the world of Gensokyo and it is Hina's ability and duty to uphold it. The concept of misfortune is mysterious and abstract. It is similar to sin or impurity, or perhaps both. The distinguishing characteristic of misfortune is that it can be transferred to someone else and then washed away to some far off distant place. It is said that there are three major ways in which someone can gain misfortune. The first way is fairly similar to sin and impurity in that it is dealt out by a godlike being. The second is when it occurs naturally. The concept of yakudoshi, which is a traditional Japanese belief that certain ages are unlucky, is an example of this as the misfortune naturally occurs from the changes in one's body and their age. The final way is when misfortune is applied by other people, also known as a curse. Most humans cannot deliberately cast a curse on someone, so misfortune generally only accumulates due to people cursing others inadvertently or with only the faintest awareness that they are doing so. Even if this is the case, the curse will still take affect and misfortune will accumulate over time, which could threaten the life or cause disaster for the one cursed. This is why many villages and communities perform rituals to cleanse misfortune. Nagashi-bina is one of these rituals. It involves placing dolls in small boats and floating them down a river, carrying the sins and impurities of their former owners with them. However, the nagashi-bina ritual only came to be this way after many years of tradition. It probably involved floating something other than dolls down the river at first. Hina could know the truth of this ritual's history and may be bearing it along with the weight of her very important responsibility.
