Episode 2 of Kamen Rider MY-TH, scheduled for September 13, 2026, puts DATT at the center of the series' next shift in dynamics. The official preview confirms that she appears while Sora is already dealing with a new Fukashigi, transforms into Kamen Rider DATT, and attacks it. When MY-TH intervenes, the situation is officially described as a three-way battle. The key is not to go beyond that: the synopsis still does not explain why MY-TH interrupts DATT or confirm that the two have become enemies.
What the official episode 2 preview confirms
TV Asahi's story page lists the second episode for September 13, 2026. While Tatsuomi continues his investigation after infiltrating the Mizuki household as a tutor, a new Fukashigi appears. Sora transforms into MY-TH; DATT then arrives, transforms into Kamen Rider DATT, and attacks the creature.
The official description adds a combat detail: DATT uses her jumping ability to pressure the Fukashigi. Before the situation is resolved, MY-TH steps into the action and the confrontation becomes a three-way fight. That wording comes directly from the preview on TV Asahi's official episode 2 page.
Who DATT is in Kamen Rider MY-TH
DATT is a member of the Twelve Zodiac Alliance associated with the rabbit. According to her official character profile, she transforms into Kamen Rider DATT, has keen hearing that lets her detect the appearance of Fukashigi, and takes particular pride in her speed. She also carries a pocket watch to time herself and is described as deeply devoted to Kamuri, the organization's leader.
Those details help explain why the preview emphasizes mobility and jumping, but they should not be used to fill in gaps before the episode airs. The official profile establishes her abilities and place in the organization; it does not, by itself, reveal the specific reason for any possible clash with MY-TH. The profile is available on TV Asahi's character page.
Why the fight becomes a three-way battle
The confirmed sequence is straightforward: a Fukashigi appears, MY-TH enters the fight, DATT arrives and attacks the same creature, and MY-TH later intervenes while DATT is pressing it. That is the point at which the official synopsis says the fight becomes three-sided. The combat triangle is therefore MY-TH, DATT, and the Fukashigi.
What the preview does not explain is MY-TH's exact reason for intervening. It also does not say that DATT arrives with a mission to defeat MY-TH. Because both Riders are initially shown confronting the Fukashigi, presenting DATT in advance as a villain, a permanent enemy, or Sora's declared rival would go beyond the official material available before broadcast.
What to remember from episode 1
The first episode introduced Sora Otosumi as the Mizuki family's meister and the man who transforms into Kamen Rider MY-TH to protect Yuna Mizuki and fight the Fukashigi. At the same time, the Twelve Zodiac Alliance, led by Kamuri, resumes activity after a hundred-year sleep and also acts against those creatures. The official episode 1 synopsis establishes those two fronts.
It is also useful to remember Tatsuomi Asao. His official profile reveals that he is a member of the Twelve Zodiac Alliance and is trying to uncover Sora/MY-TH's secret. On Kamuri's orders, he enters the Mizuki household as Yuna's private tutor to continue the investigation. That explains the episode 2's other thread: while DATT appears on the battlefield, Tatsuomi continues investigating from inside the residence. The information is on Tatsuomi's official profile.
Confirmed by the preview vs. speculation
| Question | What is confirmed before broadcast |
|---|---|
| Is DATT part of the Twelve Zodiac Alliance? | Yes. Her official profile identifies her as the rabbit member. |
| Does DATT transform in episode 2? | Yes. The synopsis says she transforms into Kamen Rider DATT. |
| Is there a three-way fight? | Yes. The preview describes MY-TH, DATT, and the Fukashigi in the same confrontation. |
| Does DATT arrive to defeat MY-TH? | That is not confirmed. The preview says she attacks the Fukashigi. |
| Why does MY-TH intervene? | The specific reason has not been revealed in the official synopsis. |
| Will DATT become MY-TH's permanent rival? | That cannot be concluded from the episode 2 preview alone. |
What to follow without turning a preview into a spoiler
To start episode 2 with the necessary context, three facts are enough: DATT belongs to the Twelve Zodiac Alliance and represents the rabbit; Tatsuomi is undercover in the Mizuki household investigating MY-TH; and the next battle will bring MY-TH, DATT, and a Fukashigi together. The TTFC supplementary series Jūnishi Toiro expands on the Twelve Zodiac Alliance, but it is not required to understand what the main preview already confirms.
Until the episode airs, any explanation of DATT's real intentions, the cause of MY-TH's intervention, or the consequences of the confrontation should be treated as speculation. The safest reading is also the simplest: DATT officially enters the action in episode 2, demonstrates her abilities against a Fukashigi, and MY-TH's intervention turns the battle into a three-sided conflict.
