Yumemizuki Mizuki — Genshin Impact

Long before Aisa Bathhouse, Mizuki admired the young Yae Miko at youkai gatherings. Their closeness changed after a dark calamity devastated Inazuma. Mizuki’s people escaped the fighting but returned to ruins; the disappearance of Kitsune Saiguu and Miko’s visible grief made the cost of the disaster painfully immediate.

Mizuki devoted herself to survivors haunted by trauma and nightmares. Having learned to feel the emotions she consumed, she suffered whenever she took on particularly toxic dreams. The strain was serious enough that an elder of the baku fell into a coma for months after helping traumatized samurai. Mizuki continued her work while Miko shouldered the shrine’s responsibilities, and the old friends gradually found it harder to share the easy companionship they once had.

Realizing that even her own powers could become dangerous when confronted with severe trauma, Mizuki traveled through other nations to study treatment methods. Her discoveries eventually brought her to Natlan, where she drew inspiration from the people’s active lives, their enjoyment of hot springs, and their balance between strenuous pursuits and rest. She returned with a plan to make well-being more than a single medical appointment.

During her long search for a better way to help people, a dream of her younger self sharing a meal with Miko by a ramen stall preceded the appearance of her Anemo Vision. That personal memory helped crystallize an approach centered on the things patients cherish, rather than an impossible universal dream that would cure everyone.

The Traveler and Paimon first encounter Mizuki in a strange dream. After accidentally consuming one of the Traveler’s pleasant dreams, she apologizes and offers a VIP visit to Aisa Bathhouse. Despite its warm hospitality, the bathhouse is losing customers. Yae Miko urges Mizuki to sell her shares and invest elsewhere, but Mizuki refuses to abandon the business. The Traveler and Paimon also meet Mizuki’s fellow baku, Shion and Murasaki.

Miko points the group toward a competing counselor called Emura Ichigensai, who claims to relieve people of all unhappiness. Mizuki’s colleagues realize that the man behind the business may be Emura Chuuya, a former patient whose difficult behavior had caused problems at the bathhouse. When two of his customers bring unusually toxic nightmares to Shion and Murasaki, the danger becomes urgent.

Mizuki and the Traveler discover that the supposedly successful therapy relies on suppressing painful feelings rather than resolving them. In the dreamscape, Chuuya’s buried memories reveal childhood rejection, including hostility toward his ambition to write. Mizuki helps him face feelings he had been taught to conceal, making it possible for her to consume the nightmares bound to them.

The real instigator is Kuroyume, a nightmare entity and the last survivor of a kind that feeds on worsening emotional torment. He has made Chuuya a host and intends to exploit the connected dreams of Inazuma. Mizuki rejects the promise of perpetual happiness because suppressed suffering does not disappear; it grows more dangerous while hidden.

Kuroyume draws the group into the borderland, a space deep within Inazuma’s collective subconscious. Mizuki and the Traveler gather sweet dreams to resist him, but their strength proves insufficient until the Traveler offers a treasured good dream. Reinvigorated, Mizuki helps turn the battle in their favor.

They discover that Chuuya is in immediate danger of drowning outside the dream and escape in time to save him. Over Narukami Island, Mizuki calls on fellow yumekui-baku to consume the nightmares that threaten its people. The victory shows both her power and the importance of a community working together instead of leaving the burden to one healer.

After Kuroyume is defeated and the nightmares are cleared, Mizuki admits to the Traveler that she has long worried about the fate of the yumekui-baku. Her hope is that people might learn to understand their emotions so well that they no longer need baku to remove their nightmares, leaving more room for happy dreams. The Traveler’s own dreams convince her that this hope is possible; on a quiet branch beneath the moon, she finds reassurance for doubts she has carried for years.

In the aftermath, Shion and Murasaki recover and customers return to Aisa Bathhouse. Miko reports that Chuuya has been rescued and is no longer in immediate danger, although his mind has regressed to a childlike state. Mizuki thanks Miko for her help and acknowledges how her feelings of inadequacy beside her accomplished friend have also driven her to persevere. Their frank exchange makes room for mutual concern rather than an easy declaration that their differences are over.

The quest concludes with Mizuki still committed to her bathhouse and its patients. Genshin Impact’s continuing story does not present this episode as a definitive end to her life or career.

In the later Travelers’ Tales anecdote, the Sumeru scholar Layla visits Aisa Bathhouse while struggling with academic work and disrupted sleep. Mizuki gives her space to discuss her concerns and leads her through a calming treatment without pretending that one session can answer everything.

After the session, Layla reports sleeping comfortably and feeling clearer, with renewed confidence in writing her abstract. Mizuki encourages her not to cling too tightly to the dream itself and arranges a follow-up, showing the ordinary, attentive side of her work beyond the extraordinary nightmare crisis.
