After cross-referencing anime databases (MyAnimeList, AniList, ANN), no exact match exists. However, the closest candidates by plot:

| Anime Title | Similarity | Difference | |-------------|-------------|-------------| | Haganai NEXT (Season 2 of Boku wa Tomodachi ga Sukunai) | A girl (Yukimura) frequently falls for Kodaka; comedic falls happen | No "2nd floor" specific key title | | The Pet Girl of Sakurasou (Sakurasou no Pet na Kanojo) | Mashiro is clumsy; falls? Rare | Second floor (dormitory) plays role | | My Teen Romantic Comedy SNAFU (Oregairu) | No falls but similar rom-com tropes | Not matching | | Aho Girl | Girl falls from 2nd floor often (Yoshiko is an idiot) | Title differs |

One strong possibility: Aho Girl (2017 anime, 12 episodes + OVA) – The protagonist, Yoshiko Hanabatake, frequently falls from her classroom window (2nd floor) or jumps down, leading to gags. But the title is not "Joshi Ochi."

Another: Joshikousei no Mudazukai (Wasteful Days of High School Girls) – Has a scene where a girl falls from a window but not the core title.

Thus, no official anime bears this exact name.

| Season | Visual Motif | Musical Cue | |--------|--------------|-------------| | Spring | Cherry blossoms swirling with pastel clouds, each girl arriving on a petal‑shaped parachute. | Light harp with fluttering woodwinds. | | Summer | Sun‑glare reflections on water, girls shimmering like droplets. | Up‑tempo acoustic guitar with beach‑side percussion. | | Autumn | Golden leaves spiraling down, each fall accompanied by a soft rustle. | Warm strings and a gentle accordion. | | Winter | Snowflakes forming delicate origami shapes as they land. | Sparse piano with chime bells, evoking quiet wonder. |

The animation style blends crisp, modern line work (for everyday life) with soft, painterly textures (for the falling sequences), reinforcing the contrast between the mundane and the magical.

The episode that perhaps best matches the title's imagery involves Nana Shirai, who, while trying to secretly observe Taro Yamada who's been helping her with her studies, ends up on the second floor. A series of comedic mishaps leads her to tumble down, causing a sensation among the students. This incident brings Taro and Nana closer, sparking rumors and romantic tensions.
