Bakemonogatari, Uchiage Hanabi, Shita kara Miru ka? Yoko kara Miru ka? Recommendations
Same art style, sound design, similar look between the female lead in Uchiage Hanabi and Senjougahara, and the supporting guy in Uchiage Hanabi with Araragi. Some Akiyuki Shinbo's trippy visuals.
There's so many similar stuff like the art style it's exactly the same, Also, confusing plot, the main girls looks pretty similar, both anime has some weird scenes but if you thought about them you would find them meaningful
