Kudryavka, also known as "Kud" (for short, is a girl who is a quarter Japanese, and three-quarters Russian. Her full Russian name is Kudryavka Anatolyevna Strugatskaya. Her grandmother is Japanese. Her grandfather was crazy about Japanese culture and per his influence on her, she came to know much about Japanese culture too, including the language. Despite having a poor handle on the English language, she was able to skip a year in school due to credits obtained through studying abroad. She is Riki's classmate and is in the newly-formed home economics club due to an invitation of the head of the dormitory she lives at with the other characters. Kudryavka and the dormitory head are the only two members, and since the latter is often too busy, club activities are suspended and Kudryavka is the sole active member of a club on the verge of being disbanded. Before joining the home economics club, Kudryavka had been a member of the furniture club before it was disbanded.
Kudryavka has two dogs: a large female Siberian Husky named Strelka , and a small Schipperke named Belka. The hat and cloak that she wears were handmade. She spent most of her childhood traveling around the world, and her home country is a small, fictional southern island (called Tebwa, or otherwise Republic of N.T.M.T, a former Soviet Union territory) closer to the equator; this is the reason for her hat and cloak—she finds Japan cold due to her country's climate. Her favorite phrase is wafu!. For the two endings, she can either choose not to return to her home country and become overwhelmed with guilt and regret when she sees her mother's public execution on television, which results in her bad ending; or, for the good ending, she chooses to return but gets captured by rebels in her home country (which is in a state of civil war), eventually escaping prison and returning to Japan due to her strong love for Riki.
Along with Komari, is one of the weakest character in the game, and since she does not have the growth rate of Komari, her usage can be quite limited. In battle, however, Kudryavka can use dog items to summon her dogs as a weapon, which can often turn the tide of the battle. In baseball, she does surprisingly well in catching balls, and like Komari, her bonus increment statistics by hitting balls to her is fairly large, so she is a good choice as an outfielder.
Kudryavka's route includes an Easter egg ending, called "Muscle Sensation". To watch this, the player must choose to play with Masato every time the choice is presented throughout her route, and generally choose choices that favor Masato, such as who Kudryavka should study with, while going through Kudryavka's route. This ending is not required to progress the game—it is simply there for humorous factor.
