Reference excerpt

With You and the Rain (Japanese: 雨と君と, Hepburn: Ame to Kimi to) is a Japanese manga series written and illustrated by Ko Nikaido. It has been serialized in Kodansha's seinen manga magazine Weekly Young Magazine since August 2020. A 12-episode anime television series adaptation produced by Lesprit aired from July to September 2025.

Plot 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.

Characters Fuji (藤) Voiced by: Saori Hayami (Japanese); Alexis Tipton (English) Fuji is a novelist characterized by her relaxed and introverted demeanor, though she possesses a deeply sensitive nature. She has a particular fondness for rainy weather. During the rainy season, she encountered You inside a cardboard box and subsequently chose to cohabit. 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. Demonstrating notable intelligence, he comprehends human speech and communicates by writing words on flip charts. His primary affinities include food and the company of Fuji, with whom he shares a close bond. Kii Ella Krause (クラウゼ・エラ・希依, Kurauze Era Kii) Voiced by: Yuzu Yumoto (Japanese); Lara Woodhull (English) A well-mannered and inquisitive first-grade student, she resides adjacent to Fuji's home. As a pupil at an international school, her mixed heritage includes a German mother and Japanese father. She owns a pet dog named Kinako and demonstrates particular interest in You. Her curious nature manifests in frequent observations about the unusual pet next door. Tatsuo (辰雄) Voiced by: Yōji Ueda (Japanese); Brian Mathis (English) Fuji's father. A seemingly stern but fundamentally warm-hearted person, he demonstrates deep familial devotion through frequent visits to his daughter Fuji's residence. Despite his initially intimidating appearance, he possesses an unexpectedly playful disposition. His visits, while motivated by care, result in Fuji's avoidance behavior that leaves him experiencing subtle loneliness. Michiko (道子) Voiced by: Mie Sonozaki (Japanese); Leslie Collins (English) A composed and articulate woman, she serves as the stabilizing presence in the family unit. Her demeanor is marked by measured speech and deliberate actions, with particular attention devoted to her husband Tatsuo's well-being. She enforces strict household prohibitions against smoking and excessive snacking, reflecting her health-conscious values. She maintains a detached attitude towards You. Veterinarian (獣医さん, Jūi-san) Voiced by: Chafurin (Japanese); R. Bruce Elliott (English) A compassionate veterinary practitioner operating a clinic in proximity to Fuji's residence.

Reception In a review of the first two volumes, Rebecca Silverman of Anime News Network praised the series for its art and its story, stating, "With You and the Rain is a slow, sweet story about the bond between a woman and her pet.

Worked examples

Example 1 — a first encounter with With You and the Rain

Start with the simplest possible case. Write down what With You and the Rain claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to With You and the Rain before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about With You and the Rain ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of With You and the Rain

In research: With You and the Rain appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses With You and the Rain in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: With You and the Rain is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2020 manga, 2025 anime television series debuts, Anime series based on manga, so understanding it makes those chapters shorter.
