Mao (Series)

Mao is a manga series written and illustrated by Japanese manga artist Rumiko Takahashi. The series began serialization on 8 May 2019 in Weekly Shōnen Sunday, a weekly magazine published by Shogakukan. This series, following Takahashi’s earlier works such as Inuyasha and Ranma ½, is regarded as one of the most significant supernatural fantasies in her career.

Mao is built on a narrative structure that unfolds in parallel between modern Japan and the early 20th-century Taishō period (1912–1926). The story’s universe presents a reality centered on supernatural events, spiritual entities, and the practice of traditional Japanese occultism known as Onmyōdō (Yin-Yang doctrine).

The key elements defining this universe are:

• Timeline and Portals: The story connects two distinct time periods through the protagonist’s journey from the modern world into the Taishō era via a sealed area in a shopping mall. Transitions between these eras occur by crossing specific supernatural thresholds.
• Gogyō (Five Elements) Clan: At the heart of the universe lies this clan composed of sorcerers who control the elements of Fire, Water, Earth, Metal, and Wood. Each element has its own unique techniques and hierarchical structure.
• Byōki and the Curse Mechanism: The power dynamics in the series revolve around “Byōki,” a powerful cat demon (ayakashi), and its lasting effects on the characters. This curse grants its bearer immortality or extraordinary abilities while simultaneously inflicting physical and spiritual decay.
• Ayakashi and Supernatural Beings: The narrative features various spiritual entities and monsters that remain hidden from society or congregate in specific regions, capable of interfering with human life.

In this universe, the modern world of technological advancement coexists with the active presence of spiritual beliefs and sorcery from historical traditions.

Mao centers on Nanoka Kiba, a middle school student who survived a mysterious traffic accident eight years ago that claimed her family’s lives. When Nanoka passes through a portal at the accident site, she enters the Taishō era and encounters Mao, an Onmyōji (sorcerer/exorcist).

The central developments in the plot are as follows:

• Nanoka’s Transformation: After the accident, Nanoka discovers unusual physical abilities within her body that are not typical of a human. These abilities emerge as a result of her interactions with entities from the Taishō world.
• Shared Curse: Mao and Nanoka’s paths converge because both are cursed by the powerful cat demon Byōki. Mao is one of the few survivors of a tragic event that occurred nearly 900 years ago in an Onmyōdō temple, which resulted in the death of all its disciples.
• Revenge and Quest: Mao travels in search of Byōki, the entity that cursed him and was responsible for the massacre in his past. Nanoka joins Mao to understand the cause of the changes in her body and uncover the supernatural truths behind her family’s death.
• Gogyō Clan Conflict: As the story progresses, the plans of Mao’s former classmates—other sorcerers specialized in different elements—spread into both the modern world and the Taishō era, becoming integral to the plot.

The narrative follows the two main characters as they solve individual supernatural incidents while gradually uncovering the true identity of Byōki and the chain of betrayals within the clan.

Mao features a darker atmosphere compared to Rumiko Takahashi’s previous works and is built around themes that blend traditional Japanese folklore with modern mystery elements.

The central themes and narrative features of the series include:

• Time and Duality: The contrast between modern rationality and the mysticism of the Taishō period forms a foundational pillar of the narrative. The transitions between the two time periods symbolize the characters’ confrontations with past traumas and future destinies.
• Immortality and Curse: In the series, immortality is not portrayed as a desirable state but as a physical and spiritual burden—a “curse.” The regrets and thirst for revenge accumulated over centuries of extended life serve as the primary motivators for the characters.
• Personal Identity and Belonging: Particularly through Nanoka’s character, the narrative explores the process of accepting one’s nature—whether human or demon—and themes of belonging within society.
• Mystery and Detective Elements: The narrative style goes beyond a conventional battle manga, adopting a mystery structure in which clues are gathered and past events are slowly revealed. Each episode is built around solving minor supernatural incidents that contribute to the overarching plot.
• Visual Language: Rumiko Takahashi’s signature clean linework is used in this series to emphasize dark fantasy elements. Demon designs and magical scenes are presented in harmony with the aesthetic details of the Taishō period.
