Tenma Momoe is a classmate of Harutora Tsuchimikado and the others at the Onmyo Prep School. He is a skinny boy with a baby face and glasses who seems shy at first glance, but soon becomes the group’s first friend thanks to Touji Ato’s involvement. Although he is barely noticed by the Onmyo Agency and seen as plain or average in skill, Tenma’s unremarkable reputation lets him quietly pull off brave actions that help turn the story around for everyone. He was raised by loving grandparents after his parents, inventors of a popular shikigami product, passed away. His kindness, loyalty, and hidden resourcefulness make him stand out, especially when he supports Natsume Tsuchimikado even after her secret is revealed. As the story continues, Tenma’s growth and inventiveness — especially his unique shikigami, Uma — add excitement and emotional strength to the group.
Tenma Momoe is slender and wears glasses, which have become his signature look.
He has a youthful, innocent face that makes him seem even younger than he is.
Tenma is the definition of a good-hearted boy.
He is friendly, a little shy, but also surprisingly upbeat and sometimes “accidentally” funny.

He is loyal, caring, and always tries to help.
Tenma comes from the Momoe family, one of the traditional onmyoji families.
He was raised by his strict but loving grandparents after his parents died.
Though he has a good relationship with his grandparents, he feels a bit distant inside because his parents married against the family’s wishes, creating some family tension.
Tenma is truly hard-working in his studies, but he considers his own abilities to be average compared to his peers.
He struggles internally with not having any special talents like the others.
His biggest achievement comes when he learns stealth jutsu (Invisibility), allowing him to sneak through the Onmyo Agency — full of monsters and danger — all by himself.
He manages to unseal the powerful Kuraha, showing great bravery and growth.

Tenma’s glasses are a unique, personal symbol for him.
He often feels overshadowed by his friends, but finds new strength and hope from their support.
Becoming Friends in the Onmyo Prep School
Tenma joins Harutora and the others at the Onmyo Prep School.
Touji Ato reaches out to him first, helping Tenma become the group’s very first friend.
While he is very unremarkable and not noticed by most, this allows him to operate in the background without being watched.
Support for Natsume Tsuchimikado
When everyone discovers Natsume is really a girl, Tenma keeps supporting her and never judges her.
He feels grateful after Natsume saves his life and starts to think about how he can help her.
Family and Hidden Strength
His parents were normal in onmyoji skills, but invented a popular type of mass-produced shikigami product.
Tenma struggles with his self-worth, thinking he isn’t unique, but Jin Ootomo’s use of a common shikigami helps Tenma realize there are many ways to be a helpful onmyoji.
Operation: Rescue Harutora
Tenma decides to help in the plan to rescue Harutora, but changes ideas after advice from Suzu Saotome.
He sneaks into the Onmyo Agency by himself, learns stealth techniques, and bravely passes through all the dangers.
He breaks the seal on Kuraha, which is a huge accomplishment.
Secret Support and Invention
Tenma continues to train in secret, not letting the Agency discover him.
When Natsume returns to Tokyo, Tenma gets a message from Akino and secretly sends a coded message back to his friends by tampering with the New Year’s event broadcast.
Helping Natsume Again
After hearing the news about Natsume’s escape, Tenma’s grandparents help him leave home.
He brings along his special shikigami, Uma, and hurries to Natsume’s side.
Uma — The Special Shikigami
Uma is a machine type shikigami modeled after a Hummer H1 and can move by itself without a driver.
It is protected with a magical barrier and has finding abilities.
According to Suzuka Dairenji, Uma is actually a group of shikigami in one body, led by a central shikigami like an operating system.
This uses a new, revolutionary technique that goes beyond both Imperial and Universal Styles.
Tenma’s creative abilities and his bond with friends make him a key part of the story’s future.
