Shinonome (a Touhou LW original) refers to the early morning when the eastern sky grows steadily brighter. It is the temperament of Kutaka, who has long overseen the passage of souls between worlds as a member of the Spirit River Railroad. Kutaka's temperament has undergone soul modulation at the fundamental level. Souls are hard to control, but the employees charged with their management at the Spirit River Railroad do not allow change (Moon Essence) or selfishness (Star Essence).

The ability of Kutaka Niwatari from the Spirit River Railroad (a Touhou LW original). It is essentially unchanged from our version of Kutaka's ability. However, since there are many mysteries surrounding the railroad and those associated with it, it's predicted that some things about this Kutaka's ability are fundamentally different, just as they are for Eiki's. While she's a god of chickens capable of healing throat illnesses, her ability as a clerical god who manages the checkpoints of the worlds that come after death has been enhanced to a greater degree. Surely everyone has thought about the afterlife. Most people probably thought particularly seriously about it during their youth. But after becoming adults, the majority of them stop thinking about it entirely, even though they've attained no certainty on what awaits them after death. Those who never stopped or couldn't stop thinking about it have visions of the worlds after death. In the future, these worlds made peculiar advances to become the Spirit River Railroad, where this world's Kutaka works as a guide. In the past, it was said birds carry spirits. Echoes of this can still be observed in the stories about stalks delivering newborn babies. Roosters (male chickens) appear in legends as creatures that rule over early morning waking. They are strongly tied to the image of the rising sun and the start of a new day, as well as to the resurrection of the dead. Without Kutaka's guidance, souls of the deceased would surely be cast out into space and become lost. It's said that, so long as they can hear her song and whistle, they are at ease. Perhaps you have memories of it too. A person with white wings, an angel, stretching out a warm hand to pull you from a dark dream... As the enclosed space of a train station expands, it's somewhat inevitable that it transforms into a complex labyrinth. This transformation is all the more pertinent if the station resides in an underground ward. It's long been accepted that underground structures are generally prisons, tombs, or storage spaces. In other words, places of punishment, places to seal away the dead, or places to store resources over long periods of time. That's right, all of the above perfectly describes Hell. Such places utilize complex designs to prevent escape and theft, and depending on the circumstances, may also place traps. Given the structures' purpose, they simply can't be easy to navigate or leave. And so guides are required in train stations, railways... and Hell. "Tweet Tweet Whistle" is the not-so-elegant name of Kutaka's whistle, believed to have been thought up by Piyo Sensei. However, the whistle itself has no special power. Getting souls to line up is not the whistle, but Kutaka's voice coming through it. As such, her singing voice also has the power to make souls line up. The voice is made of (sound) waves, and by using a voice that directly affects the spirit, Kutaka can cause souls to act. This effect is similar to the poltergeist sisters' performances. Whistles amplify the voice, so the Tweet Tweet Whistle is a convenient tool for Kutaka to have at work. Although, if Kutaka did lose her voice from speaking loudly, she could always just heal it herself...
