Spoiler-free review
Some anime you love. Some anime you hate. And some anime you keep watching every season while actively complaining about them.
Rent-a-Girlfriend is exactly that kind of show.
Rent-a-Girlfriend Season 4 — also known as Kanojo, Okarishimasu 4th Season — aired during Summer 2025, produced by TMS Entertainment and streaming on Crunchyroll. Across 12 episodes, it delivers more of the same chaotic, awkward, emotionally messy romance fans already know.
And yes, this review is completely spoiler-free.
Here’s the quick answer: Rent-a-Girlfriend Season 4 is worth watching if you’re already invested in the series. It doesn’t fix the franchise’s biggest problems, but if you still care about Kazuya and Chizuru’s relationship, there’s enough drama, tension, and emotional momentum to keep you watching.
Quick Verdict: Is Rent-a-Girlfriend Season 4 Worth Watching?
Let’s not waste your time.
Yes, watch it if:
- You already watched Seasons 1–3
- You care about Kazuya and Chizuru’s relationship
- You enjoy messy romance anime
- You like slow-burn romantic tension
- You accept Rent-a-Girlfriend as a guilty pleasure
No, skip it if:
- You disliked the earlier seasons
- You wanted Season 4 to change the formula
- Kazuya’s behavior already tested your patience
- You need fast romantic progress
- Cringe comedy is not your thing
Season 4 keeps the same strengths and weaknesses as the previous seasons. Chizuru remains the emotional highlight. Kazuya remains divisive. The slow-burn is still very, very slow.
What Is Rent-a-Girlfriend Season 4 About?
Rent-a-Girlfriend Season 4 picks up after the events of Season 3. Kazuya is still trying to understand his feelings for Chizuru, while the fake relationship that started everything continues to create tension around them.
Chizuru remains the emotional center of the story. The complicated mix of secrets, family pressure, romantic confusion, and unresolved feelings keeps building — slowly, awkwardly, and very much in the style this franchise is known for.
Ruka, Mami, Mini, and Sumi also return, each bringing a different kind of pressure, chaos, or emotional contrast to the situation.
No major plot twists here. No manga spoilers. No ending details.
Just know this: if you’re looking for quick resolution, Season 4 is not in a hurry.
What Works in Rent-a-Girlfriend Season 4
Chizuru Remains the Emotional Core of the Series
Chizuru is still the main reason many viewers stay with this anime.
She has more emotional weight than the typical rom-com heroine, and Season 4 continues to use her quieter moments well. She doesn’t always need a dramatic speech to make a scene work. Sometimes a small expression or a restrained reaction says enough.
If Season 4 has a soul, it’s Chizuru.
The Romantic Tension Still Works
The slow-burn between Kazuya and Chizuru is frustrating.
That is also, unfortunately, the point.
The entire series runs on that uncomfortable will-they-won’t-they energy. Season 4 doesn’t suddenly make the relationship clean, mature, or easy. Instead, it leans into the same emotional tension that has kept fans watching since the beginning.
Is it satisfying in a traditional way? Not always.
Is it addictive if you’re already hooked? Absolutely.
The Drama Feels Personal
At its best, Rent-a-Girlfriend Season 4 works because the drama feels painfully human.
Family expectations, hidden truths, romantic pressure, insecurity, jealousy, and fear of rejection all play a part. The characters often make bad decisions, but those bad decisions usually come from recognizable emotions.
That’s where the show still has power.
Even when the pacing drags, the emotional messiness can feel strangely real.
The Familiar Rom-Com Energy Is Still There
Awkward comedy. Bad timing. Overthinking at maximum volume. Romantic interruptions at the worst possible moment. Scenes so uncomfortable you want to look away, but somehow keep watching.
That’s the Rent-a-Girlfriend formula.
Whether that sounds like a strength or a warning depends entirely on your relationship with the series.
What Doesn’t Work in Rent-a-Girlfriend Season 4
Kazuya Is Still Very Frustrating
Let’s be honest: Kazuya remains one of the most divisive romance anime protagonists around.
He overthinks everything. He lacks confidence at critical moments. He often makes situations worse because he can’t communicate clearly or act decisively.
For some viewers, that makes him relatable. For others, it makes him exhausting — especially four seasons in.
Season 4 works best when it focuses on Kazuya’s sincerity. It works worst when his anxiety and hesitation drag scenes longer than they need to go.
The Pacing Can Feel Slow
This season is deliberately slow.
Emotional payoffs are delayed. Conversations stretch. Some scenes feel like they are circling the same feelings the show has already explored before.
For longtime fans, that slow build may feel like part of the ritual. For casual viewers, it may feel like the anime is testing your patience on purpose.
If you want clear romantic progress every few episodes, Season 4 may frustrate you.
Some Side Characters Feel Underused
Ruka brings pressure. Mami brings unpredictability. Mini and Sumi bring charm, comedy, and emotional balance.
The problem is that Season 4 keeps its focus tightly on the main romantic drama, which means some side characters don’t get as much room to shine as fans might want.
Mini and Sumi, especially, are the kind of characters who can lighten the mood and balance the heavier emotional tension. More time with them would have helped the season feel less narrow.
The Formula Has Not Changed Much
Season 4 is not a reinvention.
It is a continuation.
If you loved the earlier seasons, that may be good news. If you were hoping this would be the season where Rent-a-Girlfriend suddenly became a completely different anime, you’ll probably be disappointed.
The show is still awkward, slow, dramatic, messy, and occasionally hilarious in ways that feel almost painful.
In other words: it is still very much Rent-a-Girlfriend.
Character Review
Kazuya Kinoshita
Kazuya is still anxious, emotional, and deeply invested in Chizuru. He can make you cringe and root for him in the same scene, which is both his biggest weakness and his strange appeal.
His sincerity remains his strongest trait. When the story lets that sincerity shine, he becomes much easier to support.
Chizuru Mizuhara
Chizuru is still the strongest character in the series.
Her emotional complexity carries much of Season 4, and her restrained personality gives the drama most of its weight. She doesn’t need to be loud to dominate a scene.
The show is simply better whenever she is at the center.
Ruka Sarashina
Ruka continues to add pressure to the romantic drama.
Depending on the scene, she can be funny, frustrating, sympathetic, or exhausting — sometimes all at once. Her role in Season 4 works because she forces tension into situations where other characters would rather avoid it.
Mami Nanami
Mami remains the wild card.
Whenever she appears, the atmosphere changes. She brings unpredictability to the story and keeps viewers wondering what her next move will be.
For a series that can sometimes feel stuck in place, Mami’s presence adds much-needed tension.
Mini Yaemori and Sumi Sakurasawa
Mini and Sumi remain two of the most charming supporting characters in the series.
Mini brings energy and comedy. Sumi brings softness and warmth. Unfortunately, neither feels like the true focus of this season.
They still add value when they appear, but more screen time would have helped balance the heavier romantic drama.
Animation, Art Style, and Music
Visual Style
Rent-a-Girlfriend Season 4 keeps the clean, polished romantic-comedy aesthetic fans expect.
The character designs are consistent, the colors are bright, and the visual presentation is easy to watch. It isn’t trying to be visually groundbreaking, but it does its job well.
The animation supports the drama without distracting from it.
Character Expressions
Character expressions remain one of the show’s biggest visual strengths.
Kazuya’s exaggerated reactions carry much of the comedy, while Chizuru’s smaller expressions often carry the emotional scenes. The contrast between those two styles is one of the reasons their dynamic still works.
Even when the writing is repetitive, the expressions help sell the emotion.
Opening and Ending Themes
The opening theme, “Umitsuki” by ClariS, fits the show’s romantic and energetic tone well. It has the kind of upbeat charm you expect from a Rent-a-Girlfriend opening.
The ending theme, “Boku no Vega” by Regal Lily, is softer and more reflective, matching the season’s emotional undertone.
Both songs feel like strong additions to the franchise’s musical identity.
Rent-a-Girlfriend Season 4 Compared to Previous Seasons
Season 4 is more of a continuation than a reset.
It feels more focused on romantic tension and interpersonal drama, but it may also feel less emotionally fresh than Season 3 for viewers who strongly connected with that arc.
The core formula remains intact:
- messy romance;
- awkward comedy;
- slow development;
- emotional misunderstandings;
- Kazuya overthinking everything;
- Chizuru quietly carrying the emotional weight.
Fans who enjoyed the previous seasons will likely find enough to like here. Skeptics hoping Season 4 would change their minds probably won’t be convinced.
Who Should Watch Rent-a-Girlfriend Season 4?
Watch it if:
- You already watched Seasons 1–3
- You are emotionally invested in Kazuya and Chizuru
- You enjoy messy romance anime
- You like slow-burn relationships
- You see Rent-a-Girlfriend as a guilty pleasure
- You enjoy awkward humor mixed with emotional tension
Skip it if:
- You hated the earlier seasons
- You want fast romantic progress
- You dislike cringe comedy
- Kazuya’s personality already wore you out
- You prefer romance anime with mature, direct communication
- You need a satisfying payoff right away
Final Verdict: Is Rent-a-Girlfriend Season 4 Good?
Rent-a-Girlfriend Season 4 is not a masterpiece. It is not a disaster either.
It is exactly what it promises to be: more Rent-a-Girlfriend.
The drama works if you care about the characters. The pacing will test your patience if you don’t. Chizuru continues to be the show’s best asset, Kazuya continues to be its most divisive element, and the formula continues to frustrate and entertain in almost equal measure.
For longtime fans, Season 4 is worth watching. For casual viewers or people who already disliked the series, it probably won’t change anything.
Ratings Summary
| Audience | Rating |
|---|---|
| Longtime fans | 7/10 |
| Casual viewers | 5.5/10 |
The gap exists for a reason.
If you’re already emotionally invested, the drama may feel worth the wait. If you’re on the fence, the slow pacing and familiar frustrations may push you away.
