If you loved Kaza-hana, try P. P. Rider
Eine Brücke zwischen einem Film, den du schon gesehen hast, und einem, den kaum jemand kennt. Das teilen sie, und was der zweite macht, was der erste nicht macht.
Was sie teilen
Both films are directed by Shinji Sōmai, and they both carry the bittersweet mood tag, and they sit in Drama territory. If that's the register that drew you to Kaza-hana, the second film will land in a comparable space — through a different lens.
bittersweet
What P. P. Rider is
Teenagers stumble into the seedy underbelly of yakuza antics with all the grace of a shopping cart with a wonky wheel. The class bully vanishes, prompting an investigation that’s equal parts half-baked cops and full-throttle gangsters. More chaotic than a karaoke night gone wrong.
