NR's Eternal writes: "Tokyo Marble Chocolate is an easy gem to overlook if you weren’t around when it aired. Though it received praise at the time, the creative two-episode romance easily blends into the rest of its genre at first glance. Fortunately, the show is anything but generic. Its setup and character interaction stand out: the characters are older, presumably in their twenties, and this leads to types of interaction rarely seen in high school anime. The dialogue is sparse and the characters use internal monologues to narrate their worries while their spoken words are shackled by the niceties of the adult dating world. The story aims for realism over fantasy here, presenting romantic interaction without the dramatic exchanges often associated with anime and manga."
