In the manga, she starts off with her trademark rings already as a HiME and is fairly skilled at fighting. Though Mai seemingly died (again) in the explosion, she was shown alive and well the very next day. However, Kagutsuchi merely reformed into its jet form, Mai regenerating on top of its head and, without Mai's command or consent, flew into space, dodging all of Atremis' subsequent attacks and destroying the other child. Kagustuchi is also the only child shown to actually resist death once, when Alyssa attacked Mai and her friends with Artemis' Golden Lightning, Mai sacrificed herself by flying herself and Kagutsuchi into the path of the lightning, protecting everyone while incinerating herself and Kagutsuchi. However, when its seal is finally removed, it is doubtful that there is any Child that can come close to its power. Shizuru's Kiyohime and Mikoto's real Miroku), Kagutsuchi's power is challenged.
Toward the end of the series, when stronger Childs appear (e.g. In the beginning of the series, Kagutsuchi appears to be by far the strongest Child among other HiME's childs.
During the final battle, the HiME's attack on the HiME star weakens the Obsidian Lord and destroys the sword, loosening the control and allows Kagutsuchi full access to all its power to destroy the Obsidian Lord within Reito. The sword in its head, the Sword of Sealing, made by the Obsidian Lord, acts as a seal on its powers, allowing the Obsidian Lord to suppress it when needed. Kagutsuchi also is capable of melee fighting, and has a jet mode which allows it to travel at high speeds.
Another obvious reference is the legendary bird phoenix as Kagutsuchi is shown to be able to be reborn from fire (the fiery feathers it shed on an occasion and the general connection to fire further confirm that). Named after a Japanese god of the same name, it is also somewhat associated with whales and dolphins (hence the fin-like protrusions on its face and the sounds which it communicates with). Her Child is Kagutsuchi, a dragon-like creature capable of expelling destructive fire balls and laser-like thermal blasts. Mai's HiME mark is located on her right breast, which is said to be controlled by Cancer, her Zodiac sign. Mai also is capable of creating barriers around herself to block attacks. The rings allow her to use fire-based attacks and the power of flight. In the anime, Mai's elements are a set of four golden rings with magatama around her wrists and ankles. Mai picks up a part-time job at the Lindem Baum restaurant, where she works with her future teacher Midori Sugiura. In the following episodes, Mai continues to fight Orphans along with Mikoto and Natsuki, becoming especially close to Mikoto. Mai materializes her Elements for the first time and also acquires her Child, Kagutsuchi, which she uses to defeat the Orphan. Being informed by Nagi Homura that her brother is in a nearby forest, she finds him under attack by an Orphan. Mai meets and befriends many other students, including Mikoto and Natsuki, in episodes 2 and 3. Mikoto and a mysterious attacker (later shown to be Natsuki Kuga) battle on the ferry, revealing magical powers during this battle, Mai finds out she has powers similar to the two. Mai resuscitates a girl who was found in the river, Mikoto Minagi. On the trip, Mai meets Yuuichi Tate, with whom she begins a love-hate relationship. In the first episode, Mai and her brother Takumi take a ferry to their new school, Fuka Academy. Her stated hobbies are working part-time jobs and taking care of Takumi. She is a first-year high school student, and her roommate is Mikoto Minagi. Mai Tokiha as she appears in the My-HiME anime adaptation Mai is portrayed as a self-reliant person, hesitant to tell others about her problems.
