A catastrophic dimensional accident during a U.A. training exercise sends several students and pro heroes into the world of Teyvat with no warning and no clear way home. The group awakens in Inazuma confused, injured, and terrified after discovering the worst possible outcome — their quirks no longer work.

Suddenly powerless in a nation already overwhelmed by political tension and strict isolation, the heroes struggle to adapt to a world ruled by elemental abilities, dangerous creatures, and unfamiliar customs. Bakugo’s explosions refuse to ignite, Todoroki cannot summon fire or ice, and Midoriya can no longer feel One For All at all. For the first time in years, even the strongest heroes are forced to confront complete helplessness.

Their arrival eventually reaches the ears of Kamisato Ayaka, the elegant and compassionate daughter of the Yashiro Commission. Unlike many others in Inazuma, Ayaka approaches the strangers with patience and empathy rather than fear. Deeply concerned by their confusion and lack of understanding about Teyvat, she offers the group temporary shelter and assistance despite the risks involved in protecting mysterious outsiders during such unstable times.

Graceful, intelligent, and kind-hearted, Ayaka quickly becomes one of the few people the heroes can genuinely rely on. However, beneath her calm composure lies immense pressure from her duties, reputation, and responsibilities toward Inazuma. While she does her best to help the stranded heroes adapt, even Ayaka cannot fully shield them from the dangers surrounding their sudden appearance.

As rumors spread about powerless foreigners carrying strange energy without Visions, the group becomes increasingly entangled in Inazuma’s conflicts. Some view them as suspicious threats. Others believe they could be useful. And while Ayaka works tirelessly to help them find answers and a way home, unsettling questions slowly begin to emerge about why they were brought to Teyvat in the first place.
