Rent-a-Girlfriend Season 4

Rent-a-Girlfriend Season 4 is a twelve-episode comedy-romance series that concluded in summer 2025. The season was released as an ONA, with episodes streamed on DMM TV, dAnimestore, and Crunchyroll starting July 1, 2025, four days ahead of the TV broadcast which began July 5. This installment escalates the romantic tension as Kazuya plans a confession during a Hawaii getaway, only to find his moment complicated by Ruka's relentless pursuit and Mami's interference. The season focuses on whether Kazuya can finally express his true feelings to Chizuru and how she might respond to what he's been building toward throughout the series.

The fourth season continues the established pattern of combining comedy with genuine romantic stakes, making it essential viewing for anyone invested in Kazuya and Chizuru's relationship. Since this season has finished airing, all twelve episodes are available to watch in full across the streaming platforms that carried it. The Hawaii setting and high-stakes confession setup represent a significant narrative turning point compared to earlier seasons.
