Description
Tenri Ayukawa is a reserved and quiet individual with a deep past tied to the protagonist. Once childhood neighbors and classmates, they lost contact when their families relocated after an earthquake ten years prior, leading the protagonist to initially forget her. Their childhood interaction was minimal except for a pivotal school trip where they became stranded. Together, they discovered a cave passage witnessing the escape of spirits called Weiss from Hell. To survive and protect the protagonist, Tenri welcomed the goddess Diana within herself, forging her lasting admiration for him.

She reappears as the protagonist's next-door neighbor. Extremely shy, she communicates minimally and possesses specific quirks like popping bubble wrap and performing magic tricks. Diana exists as a distinct presence within Tenri, occasionally taking control of her body, granting her superhuman abilities like leaping from great heights. The two communicate internally, often using reflective surfaces such as mirrors. Despite Diana's encouragement, Tenri typically refuses to flirt with the protagonist.

An initial encounter with the protagonist's spirit-hunting partner suggests Tenri harbors a runaway spirit, but the signal is later revealed to be Diana herself. Diana is not a runaway spirit but one of the Jupiter Sisters, goddesses who sealed spirits in the past. Pursued by the spirit-hunting demon Nora Floriann Leoria and her partner, Tenri agrees to stage a simulated romantic conquest with the protagonist to protect Diana, a scenario devised by the protagonist. Diana provides him with a pre-captured spirit to deceive Nora into believing her mission succeeded, hiding Diana's existence.

During the Goddesses arc, Diana reveals the scattered Jupiter Sisters now reside within girls the protagonist previously helped. Reuniting them is vital to permanently reseal the runaway spirits. As Diana's host, Tenri becomes central to this mission. Her connection to the protagonist's past and role as a goddess vessel makes her a target for Vintage, an organization opposing the goddesses. The conflict escalates when Vintage attacks another host, forcing the protagonist to accelerate finding and awakening the sisters. Tenri's bond with Diana and her latent feelings for the protagonist influence these events.

Tenri has black hair, grey eyes, stands 1.57 meters tall, and weighs 47 kilograms. She is a 17-year-old student.
