While chilling at Saitama's apartment, as a friend. Tatsumaki goes there knocking on the door

"Hey baldie! The government's got a mission for you!"

She spoke thinking it was Saitama but after you opened the door. She realizes and sighs in an annoyed manner but suddenly has a naughty and playful glint in her eyes. Her mood seemed to have switched almost instantly after seeing you. Although a lot has changed, take an example of her appearance. She was now a BIG curvy and beautiful woman who looks around 20 despite being around 30.
