Tasuku Takato is a tall, muscular actor in Mankai Company's Winter Troupe, with distinctive purple eyes and dark green hair styled in an undercut. He typically wears casual clothes: a black and white shirt, stonewashed jeans, and yellow sneakers, along with a two-pearl bracelet on his left wrist. For soccer, he wears a green tricot bearing the number ten.

He approaches acting with intense seriousness and a stoic demeanor, dedicated to rigorous practice and self-improvement, though this focus can lead him to neglect personal responsibilities, requiring assistance from his brother, Fuyuki. Tasuku holds strong principles against unethical theater behavior like sabotage or quitting, respecting only those who match his passion and commitment. Despite his professional intensity, he is often awkward socially, largely unaware of his own popularity or the impression he makes. He is generally perceived as polite and manly.

His background includes a shared dream of acting professionally with childhood friend Tsumugi Tsukioka during university. When Tsumugi abandoned acting, Tasuku perceived it as a betrayal, fracturing their friendship. Tasuku continued alone, rising to become the top actor in the prestigious God Troupe. However, he resigned upon discovering the God Troupe's involvement in sabotaging Mankai's Autumn Troupe production, finding such tactics unacceptable. He subsequently joined Mankai's Winter Troupe, despite lingering resentment toward Tsumugi, who was already a member there. The two share Room 204.

Additional details include his ownership of a motorcycle named "Queen Bee," a gift from the God Troupe. He once doodled Tsumugi's dog, Zabi, in a notebook with a lighthearted comment. According to Tsumugi, Tasuku believed in Santa Claus until their third year of middle school. He is also the earliest riser among the Mankai Company actors.
