This one doesn't ambush you, it just sits with you until something gives. Twelve episodic cases, a mysterious girl flanked by a young monk and a demon doctor, and every ailment they treat turns out to be a human ache wearing a supernatural mask. There's no grand arc to chase and that's the point, each installment is a closed loop of grief, regret, or love that got said too late, and the show trusts you to sit through the quiet parts. The art carries real weight here, soft pastel washes and clean linework doing the emotional lifting that lesser shows hand to a soundtrack swell. Fans keep reaching for Violet Evergarden as a comparison, and the reason is simple, both understand that a stranger listening to one person's whole sorrow is enough of a plot. Slept on, hard. Watch it alone and keep tissues within arm's reach.

A mysterious young girl travels the world with two companions: a young monk and a serpent demon who takes the shape of a man. She is a spirit doctor famed among the yaoguai, the sentient spirits, demons, animals and forces of nature, and she wears a bell that makes no sound, though few know her face. Together the trio treats yaoguai struck by spiritual ailments and cures illnesses caused by demons and ghosts, helping humans along the way. Each story looks into a particular yaoguai and what lies behind its suffering. The 12-episode ONA blends fantasy, mystery and the supernatural.
