What if Marinette had gotten a different best friend instead of Alya? I honestly think Kagami could have worked incredibly well
I have always had this thought about Marinette’s friendships.
What if Marinette had gotten a different best friend much earlier in the series?
For years, whenever I thought about this, the two characters that usually came to mind were Chloé and Kagami. Obviously, Chloé is a much more complicated choice because of her bullying and the way she treats people, so I never really thought she would be the best option unless the show had completely rewritten her character from the beginning.
But Kagami is different.
The more I look at Marinette and Kagami’s friendship, the more I think Kagami could have been a genuinely great best friend for Marinette if she had been introduced earlier and given more consistent development.
And after Season 6, especially everything surrounding “Secret Protocol” and “Nemesis,” I think this question becomes even more interesting.
Before anyone misunderstands what I am saying, I am NOT saying Alya is a bad person or that Marinette and Alya were never good friends. They absolutely were. Alya has helped Marinette countless times, protected her secrets, supported her as Ladybug, and became one of the most important people in her life.
What I am questioning is whether Alya was necessarily the best possible friendship for Marinette from a character development perspective.
Because Kagami brings something completely different to Marinette.
I actually think Kagami and Marinette have one of the most interesting friendships in the show
The funny thing is that Kagami and Marinette did not start out as friends at all.
Kagami was introduced as someone who was competing with Marinette for Adrien's attention. Marinette was jealous of her, and Kagami initially viewed Marinette as someone standing between herself and Adrien.
Then we got “Ikari Gozen.”
That episode is honestly one of the biggest reasons I started thinking about this.
Marinette and Kagami are randomly paired together during the Friendship Day treasure hunt. Marinette initially hates the idea because she is afraid that helping Kagami win will bring her closer to Adrien.
So Marinette starts sabotaging the competition.
But Kagami is actually trying to become Marinette's friend.
That is what makes the whole thing work.
Kagami does not approach Marinette because she wants something from her. She genuinely wants to understand her.
And when Marinette discovers how isolated Kagami actually is, her entire perspective changes.
Kagami barely has anyone in her life outside of her mother and the small number of connections she has made. She was literally trying to figure out how to make friends.
That makes Marinette realize that she completely misunderstood her.
By the end of the episode, their relationship has genuinely changed.
That is a very different foundation from the way their relationship started.
Imagine if THAT friendship had started much earlier
This is where I think the show could have done something really interesting.
Imagine Kagami being introduced around Season 1 or Season 2 instead of Season 3.
Not necessarily as Marinette's best friend immediately.
Let them slowly become friends.
At first, Marinette could still be awkward around her because Kagami is extremely direct and serious.
Kagami could find Marinette confusing because Marinette constantly overthinks things, changes plans at the last second and gets extremely nervous around Adrien.
But instead of making Kagami primarily a romantic rival, the show could gradually make her a person Marinette trusts.
Kagami would become the friend who tells Marinette the truth.
Not necessarily what Marinette wants to hear.
What she NEEDS to hear.
And that is something Marinette desperately needs sometimes.
Kagami would challenge Marinette in a completely different way
Alya and Marinette are similar in some important ways.
They are both social.
They are both energetic.
They both love investigating things.
They both get excited about mysteries.
They both understand each other's social world very well.
Kagami is almost the opposite.
She is straightforward.
She is disciplined.
She is observant.
She does not always understand Marinette's complicated thought process, but she also does not encourage Marinette to spiral.
If Marinette started making one of her giant plans involving Adrien, Kagami could simply look at her and say:
“You are overthinking this.”
And Marinette would probably realize that she is.
That could have been a really healthy friendship dynamic.
Marinette could teach Kagami how to relax, socialize and express herself.
Kagami could teach Marinette how to be more direct, confident and emotionally honest.
They would actually help each other grow.
And this is why I don't think Chloé would work as well
I used to consider Chloé too.
And honestly, I still think there is an interesting alternate universe where Chloé and Marinette become close friends.
But canonically, it would require much more rewriting.
Chloé spends a significant amount of time bullying Marinette and other students.
Even when Chloé shows that she can care about people, she still has a lot of emotional issues and has to work through her entitlement and behavior.
So if Chloé were going to become Marinette's best friend, the show would need to start developing that friendship much earlier.
Kagami doesn't require nearly as much rewriting.
The foundation is already there.
The show already established that Kagami genuinely wanted Marinette as a friend.
The biggest missed opportunity was how little time they got together
This is probably my biggest criticism.
Marinette and Kagami have some genuinely good friendship moments, but the show often moves Kagami back toward being primarily connected to Adrien's storyline.
That is frustrating because Kagami has so much potential outside of Adrien.
Her friendship with Marinette could have been its own storyline.
It did not need to constantly revolve around romance.
In fact, one of the strongest parts of their relationship is when they are simply being friends.
Kagami and Marinette getting food together.
Talking.
Helping each other.
Learning about each other's lives.
Kagami being introduced to Marinette's other friends.
Those moments make their relationship feel much more natural.
And then Season 6 makes the Alya question more complicated
This is where I think the current story becomes interesting.
“Secret Protocol” puts Marinette and Alya's friendship under serious pressure.
The episode itself centers on Marinette organizing a surprise for Sabine, but the situation ultimately contributes to a much bigger emotional conflict involving Marinette's secrets. The following episode, “Nemesis,” continues directly from that situation.
I actually think this is an important distinction.
Alya being upset with Marinette does not automatically make Alya a terrible friend.
From Alya's perspective, she has spent years being one of Marinette's closest friends while Marinette has had enormous secrets that she couldn't tell her.
From Marinette's perspective, keeping secrets has literally been part of protecting Paris and protecting the people she loves.
So both sides have understandable emotions.
That's what makes the conflict interesting.
But it also makes me think about something else.
What kind of friend does Marinette actually need when her life becomes this complicated?
And this is where I think Kagami could fit incredibly well
Kagami understands secrets and complicated family situations.
She understands what it feels like to have important parts of your life controlled by circumstances outside your control.
She also understands what it feels like to be isolated.
Most importantly, Kagami tends to be direct.
If Marinette was hiding something from her, I don't think Kagami would spend months trying to guess what Marinette was thinking.
She would probably ask her.
And if Marinette couldn't answer, Kagami would probably be hurt, but she would understand that there are things Marinette cannot explain.
That doesn't mean Kagami would automatically accept everything.
She could still call Marinette out.
But she might approach the situation differently.
I think Kagami would be the kind of best friend who keeps Marinette grounded
This is probably the biggest reason I like the idea.
Marinette can be extremely emotional.
She overthinks.
She sometimes makes complicated plans instead of simply communicating.
She can become so focused on solving a problem that she doesn't stop to think about how other people feel.
Alya sometimes gets pulled into that world with her.
Kagami could provide a different balance.
She could say:
“Marinette, stop. What do you actually want?”
And that could force Marinette to think instead of immediately reacting.
At the same time, Marinette would help Kagami with the opposite problem.
Kagami can be very rigid.
She was raised in an extremely controlled environment.
She has difficulty expressing herself and making normal friendships.
Marinette could help her become more comfortable being herself.
So their friendship would not be one sided.
They would genuinely improve each other.
And I don't think Kagami would have to replace Alya
This is another thing I want to make clear.
I don't think the best version of this story is “remove Alya and put Kagami in her place.”
I think that would actually waste the potential.
A much better version would be Marinette having BOTH friendships.
Alya could remain the friend who understands Marinette's social life and her superhero life.
Kagami could become the friend who understands Marinette emotionally and helps keep her grounded.
That would give Marinette different types of friendships instead of making one person responsible for everything.
Alya and Kagami could even become friends themselves.
Imagine those three together.
Alya is investigating something.
Marinette is panicking.
Kagami is standing there wondering why either of them is making the situation so complicated.
That could be hilarious.
Kagami also has something Marinette doesn't always have
Kagami is very honest.
Sometimes almost brutally honest.
But I actually think Marinette needs someone like that.
A best friend shouldn't always agree with you.
A best friend should sometimes tell you when you're wrong.
Kagami could have been the person who tells Marinette:
“You are hurting yourself by avoiding the conversation.”
Or:
“You are assuming what someone thinks instead of asking them.”
Or:
“You don't need to solve everything yourself.”
Those are lessons Marinette could benefit from learning.
The irony is that canon already proved this friendship works
This is why I don't think this idea is completely random fanfiction logic.
The writers already gave us the blueprint.
Kagami and Marinette became friends.
They understood each other better.
Marinette helped Kagami open herself up.
Kagami became someone Marinette could trust.
Their friendship continued developing beyond the initial rivalry.
So the question isn't really:
“Could Marinette and Kagami be friends?”
The show already answered that.
Yes.
The more interesting question is:
“What would have happened if the writers had invested in that friendship as much as they invested in Marinette and Alya?”
Because I genuinely think it could have become one of Marinette's strongest relationships.
My ideal version
If I were rewriting the early seasons, I wouldn't remove Alya.
I would introduce Kagami earlier.
Maybe around Season 2.
Let Marinette meet her before the Adrien rivalry becomes such a major part of their relationship.
Give Kagami her own life outside of Adrien.
Give Marinette and Kagami several episodes where they simply become friends.
Then by the time “Ikari Gozen” happens, the episode would be less about Marinette discovering that Kagami wants to be her friend and more about Marinette realizing that she has been taking their friendship for granted.
Then Alya, Kagami and Marinette could develop into a trio.
But each friendship would remain different.
Alya would be Marinette's longtime best friend and superhero confidante.
Kagami would be the honest, grounding friend.
Marinette would be the emotional bridge between them.
That would actually make Marinette's social circle feel more realistic.
So after everything we've seen, I still think Kagami could have been an amazing best friend for Marinette
Not because Alya is evil.
Not because Alya and Marinette were never good friends.
And definitely not because Kagami is somehow a “better person” than Alya.
It's because Kagami brings a completely different personality and perspective to Marinette.
And honestly, I think that difference is exactly what makes their friendship interesting.
Marinette doesn't need five friends who all respond to her the same way.
She needs friends who challenge different parts of her personality.
Alya can be the person who understands her.
Kagami can be the person who grounds her.
And Marinette can be the person who brings them both together.
After “Secret Protocol,” I find the idea even more interesting because the series is showing just how difficult Marinette's secrets can make her relationships.
Maybe the answer was never that Marinette needed to replace Alya.
Maybe she just needed more than one truly deep friendship.
And honestly, I think Kagami was one of the biggest missed opportunities for that.
