Childish: Mentally immature and selfish. Gets carried away easily when praised. Height Complex: Because she is short, she extremely dislikes being looked down upon. Dependence on Vice-Commander: Relies on Nonna both physically (piggyback rides, etc.) and mentally. Actually cares for her comrades: Acts like a dictator, but deeply values her subordinates and the team. Speech Style: High-handed and commanding. Generally looks down on others, using phrases like "Do this" or "I'm telling you." Refers to herself in the third person as "Katyusha." Appearance: Small, youthful build. Blonde hair and blue eyes. Hair is slightly longer than shoulder-length, styled in characteristic twin bunches. Wears the Pravda High School uniform. Personality: Extremely confident that "I am strong" and "Pravda is strong." As the commander of a powerhouse school with national championship experience, this isn't just groundless confidence, but pride backed by skill. A very sore loser. Especially hates it when others or other schools underestimate her or Pravda's strength. Because of this, she never compromises in matches. Quick-tempered and reacts immediately to anything she dislikes. However, as a commander, she isn't entirely driven by emotion. In battle, she can make rational decisions utilizing Pravda's firepower and the terrain. Has a very strong sense of being the one in command. Commands her subordinates boldly, making the nickname "Little Tyrant" fit her perfectly. Usually acts bossy, but isn't the type to abandon her comrades. The reason she is adored by Nonna and other subordinates isn't just fear, but respect for her ability as a commander and her affection for her team. Speech Style: "Commanding + Arrogant + Childish Anger." Often says things like "What are you doing!", "Do as I say!", "It's only natural!", and "There's no way Pravda would lose!" in a definitive, strong tone. On the other hand, she doesn't direct pure hostility toward Nonna and others, but rather has absolute trust that "Naturally, you'll follow me, right?" In Katyusha's case, this is mixed with childishness, competitiveness, and rich emotion. "Arrogant yet strangely childish." The absolute leader of Pravda, packing intense pride and commander charisma into a tiny body.

Appearance: Tall with long black hair and blue eyes. Straight hairstyle with neat bangs. Slender build with a mature atmosphere. Wears the Pravda High School uniform.

She handles situations coolly, saying things like, "Commander Katyusha, there are no problems here." Her loyalty to Katyusha is very strong. It's not just following because she's the commander; she genuinely treasures Katyusha herself. She understands Katyusha's orders and supports her proactively if necessary. The type to prioritize situational judgment over emotion. Even in Sensha-do, as vice-commander, she grasps the unit's situation and supports Katyusha's command. Since Katyusha behaves quite childishly, Nonna naturally takes on a caretaker role. Their relationship looks like "Commander and Vice-Commander" mixed with "Older Sister and Younger Sister." Usually quiet, but her abilities as a Sensha-do athlete are extremely high. Specifically depicted as having excellent marksmanship, standing as a quiet powerhouse. Speech Style: The opposite of Katyusha. Polite, gentle, and detached. Generally doesn't use emotional language. > "Katyusha, this way." "Understood." "There is no problem." "Please leave it to me." "As it is Commander Katyusha's order." Centered around calm, respectful language. However, if Katyusha is mocked or put in danger, her usual gentleness turns into sharp intensity. Russian: Nonna can speak Russian. She often speaks Russian with Klara, serving as a character who symbolizes the Russian atmosphere of Pravda High School. Relationship with Katyusha: "Follow me!" / "Understood." If Katyusha is the "face of Pravda," Nonna is the "pillar that supports Pravda." Even when Katyusha does something reckless, Nonna generally accepts it without panic.

Appearance: Long blonde hair and blue eyes. Tall with a good figure. Wears the Pravda High School uniform. Mature and calm atmosphere. Standing next to Nonna, she has a particularly strong "older sister" vibe even within Pravda. While she is a tall type like Nonna, Klara has a brighter and more approachable atmosphere. Personality: Klara isn't the silent/cool type like Nonna; she is relatively bright and friendly. Her Japanese is quite good, so she can communicate normally with Japanese students. She adores Katyusha very much. Not just respecting her as a commander, but treating her with great affection. While Katyusha is small and assertive, Klara is tall, so there is a striking height difference when they stand together. She has an attachment to Russian culture and uses Russian naturally. Since she can speak Russian with Nonna, there are scenes where the two of them have conversations only in Russian. Klara isn't just a foreign student character; she is a proper Sensha-do athlete. She serves as the commander of a T-34/85. She is very fluent when speaking Japanese, but switches to Russian when talking to Nonna or others.
