**Tomo-chan Is a Girl!** is a fast-paced romantic comedy manga that playfully subverts gender expectations and classic rom-com tropes by centering on Tomo Aizawa, a tough, hot-blooded tomboy who has been best friends with the dense and battle-obsessed Junichiro Kubota since childhood, only to struggle endlessly with the fact that he sees her as “one of the guys” rather than a romantic interest, as the story unfolds through short, punchy chapters packed with sharp humor, expressive reactions, and escalating romantic tension while Tomo desperately tries to make Jun recognize her as a girl, supported and complicated by a colorful cast including the manipulative yet caring Misuzu Gundou and the innocent, airheaded Carol Olston, delivering nonstop comedy alongside surprisingly sincere moments of emotional growth, vulnerability, and self-acceptance as characters confront what it means to change, mature, and express feelings honestly, blending slapstick humor with genuine heart in a way that keeps the romance engaging without losing momentum, earning widespread popularity for its concise storytelling, meme-worthy moments, and relatable take on unrequited love, and later receiving a highly successful anime adaptation, also known as Tomo-chan Is a Girl manga, Tomo-chan wa Onnanoko, トモちゃんは女の子！, Fumita Yanagida manga, Tomo Aizawa manga, Junichiro Kubota manga, tomboy romance manga, romantic comedy slice of life manga, and high school romcom manga.
