With You and the Rain

Fuji is a reclusive novelist who lives alone. One rainy evening, while returning home soaked from the rain, she discovers an abandoned animal inside a cardboard box. Peering at the damp creature, she tentatively wonders whether it might be a dog. The animal responds by writing on a sketchpad: "I am a dog" and "I am easy to take care of". Convinced by these assertions, Fuji decides to take it home, naming the creature "You", and the two begin living together. Though acquaintances occasionally question You's true nature, Fuji consistently introduces it as a mixed-breed dog. Each time doubts arise, You reaffirms its canine identity through written messages. Their daily life unfolds quietly—Fuji, reserved and introspective, and You, clever and expressive—their interactions forming a gentle rhythm of companionship.

Fuji regards You as a gifted mutt and derives great pleasure from their companionship. You (君, Kimi) Voiced by: Anna Mugiho (Japanese); Derick Snow (English) During the rainy season, Fuji encountered an unnamed canine—referred to only as "You"—and took him in. You exhibits a curious and guileless disposition, with his emotions often manifesting plainly through his behavior.
