Twins in anime often bring out some of the most fascinating character dynamics—whether it’s contrasting personalities, mysterious powers, or unbreakable bonds. Let’s take a look at some of the most memorable anime twin pairs. Which duo is your favorite?
Nana & Momo
From To LOVE-Ru
These royal twins from the planet Deviluke may look almost identical—both rocking pastel pink hair with major moe energy—but they couldn’t be more different on the inside.
Nana, the elder sister, wears her hair in twin tails and is a fiery, energetic tomboy. She’s great at sports, can communicate with animals, and is a total tsundere with zero experience in love.
Momo, with her short bob haircut, is sweet and soft-spoken… until she’s not. Underneath that cute exterior lies a cunning, calculating mind. She’s got a dark streak, and she knows how to use it—especially when it comes to her own romantic schemes.
Ram & Rem
From Re:Zero − Starting Life in Another World
Arguably the most famous twins in modern anime. Working as maids in Roswaal’s mansion, Ram and Rem are fan favorites for a reason.
Ram, the red-haired elder sister, is sarcastic, sharp-tongued, and a little aloof. But deep down, she’s fiercely protective and incredibly loyal—especially toward her sister.
Rem, with blue hair and a calm demeanor, is compassionate and strong-willed. Her unconditional love for Subaru is one of the emotional pillars of the series. She’s gentle, but she’ll fight tooth and nail for what (or who) she believes in.
Yuichiro & Muichiro Tokito
From Demon Slayer: Kimetsu no Yaiba
The Tokito twins may look alike, but their personalities are night and day.
Yuichiro, the older brother, is blunt and cold, often saying harsh things. Muichiro, on the other hand, is gentle and quiet. Despite Yuichiro’s tough love, he deeply cared for his brother—and that bond remains a strong influence on Muichiro even after tragedy strikes.
Their story is one of heartbreak, survival, and growth. After their parents’ death and a demon attack, Muichiro unlocked his hidden strength and rose to become the Mist Hashira in just two months.
Kururi & Mairu Orihara
From Durarara!!
The younger sisters of the eccentric Izaya Orihara are just as bizarre—if not more.
Kururi wears short hair and a gym uniform with a gloomy air. Mairu is her complete opposite: braided hair, glasses, and bookish vibes… but don’t be fooled. She’s got a naughty side and a surprising obsession with adult novels.
They believe they’re two halves of one whole, choosing to learn different things to “complete” each other. Charming, weird, and full of surprises—that’s Kururi and Mairu for you.
Rin & Yukio Okumura
From Blue Exorcist
They may be twins, but they’re worlds apart—literally and figuratively.
Rin, the elder, inherited the demonic powers of Satan. He’s hot-headed, impulsive, and reckless. Yukio, who looks entirely human, is calm, composed, and pragmatic. The tension between them reflects the classic clash between chaos and order, heart and mind.
Yuzuru & Kaguya Yamai
From Date A Live
Originally one powerful being, the Yamai twins were split into two separate Spirits with distinct personalities.
Kaguya is flashy, impulsive, and theatrical—every word sounds like it’s straight from a dramatic stage play. Yuzuru, on the other hand, is calm and composed, speaking in clipped, two-word phrases. Initially rivals, their bond grows deeper as they learn to accept each other again.
Kyou & Ryou Fujibayashi
From Clannad
Kyou is loud, energetic, and a little rough around the edges—but her cooking is top-tier, and her loyalty is unmatched. Ryou is shy, sweet, and prefers to express herself through fortune-telling with her tarot cards.
Despite their differences, both sisters end up falling for the same boy. Talk about twin telepathy!
Takuma & Kazuma Takaizumi
From School Babysitters
Cuteness overload alert!
Takuma is the outgoing and cheerful twin—always smiling and full of energy. Kazuma, in contrast, is a teary-eyed little introvert who’s easily frightened. The two are rarely seen apart, and their adorable antics are guaranteed to melt your heart.
