Meet 10 characters like Tanjiro from Demon Slayer with unshakable optimism! These characters maintain hope even when facing impossible odds.
Tanjiro Kamado from Demon Slayer, even though an expert swordsman (that’s impressive too), is mostly known for his calm kindness. Even when facing man-eating demons who butchered his family, this resolved swordsman somehow holds compassion that borders on naivety. But Tanjiro isn’t alone in the anime-verse when it comes to characters who refuse to let darkness dim their light.
Get ready to meet some characters like Tanjiro from Demon Slayer, who are optimistic to a fault. These characters somehow manage to stay positive despite everything life throws at them!
1) Iruma Suzuki (Welcome to Demon Schoool! Iruma-kun)
Much like Tanjiro from Demon Slayer, Iruma Suzuki finds himself thrust into a world of demons — except in his case, he’s attending their school! Sold to a demon by his neglectful parents, this blue-haired human somehow maintains an impossibly bright outlook. Despite constantly fearing for his life (if his demonic classmates discover he’s human, he’s lunch!), Iruma approaches each day with genuine kindness.
He has a natural ability to see the good in everyone — even literal demons. Both characters possess a boundless empathy that transforms those around them. His tendency to help others despite personal risk mirrors Tanjiro’s compassion toward demons. It proves that sometimes being “too nice” can be your greatest weapon in supernatural worlds.
2) Shichika Yasuri (Katanagatari)
In martial arts anime, Shichika Yasuri stands out as a character like Tanjiro from Demon Slayer through his gentle path to a violent world. Grown in isolation on an island, this “sword that isn’t a sword” keeps a childlike purity that lasts even as he’s drawn into a bloody quest to collect 12 legendary blades.
Shichika’s loyalty and optimistic outlook mirror Tanjiro’s steadfast nature. Both swordsmen (though Shichika himself IS the sword) maintain their moral compass despite encountering increasingly disturbing situations. Shichika evolves from naivety without surrendering his fundamental goodness. His journey from sheltered warrior to emotionally complex hero echoes Tanjiro’s growth. Even when facing heartbreaking betrayal, Shichika never becomes cynical or vengeful.
3) Tohru Honda (Fruit Basket)
If Tanjiro from Demon Slayer had a spiritual sister, it would be Tohru Honda. After losing her mother and living in a tent, this impossibly caring girl still comes each day with a smile that could outshine the sun. When she accidentally finds the Sohma family’s zodiac curse, her reaction is understanding and acceptance.
These characters have experienced individual loss but choose to direct their pain into aiding those around them. Tohru’s persistent belief that people are fundamentally good mirrors Tanjiro’s kindness toward the demons he encounters. Her emotional intelligence allows her to see past the Sohmas’ defenses, just as Tanjiro perceives the humanity within certain demons.
4) Seth (Radiant)
Seth from Radiant could be Tanjiro’s optimistic cousin from another anime universe. Living in a world where “Nemesis” monsters fall from the sky and infected humans become feared “sorcerers,” Seth dreams of finding and destroying the Nemesis nest called Radiant.
Like Tanjiro from Demon Slayer, Seth maintains an almost reckless positivity in the face of adversity. Both characters are defined by their determination to overturn unjust systems. Tanjiro fights for demons who retain humanity while Seth battles prejudice against sorcerers. They share that rare quality of seeing possibilities where others see only obstacles. Seth’s virulent optimism slowly changes those around him, much like how Tanjiro’s compassion transforms the Demon Slayer Corps’ black-and-white view of demons.
5) Naofumi Iwatani (The Rising of the Shield Hero)
Naofumi delivers an impressive contrast to characters like Tanjiro from Demon Slayer. Summoned as the Shield Hero and instantly falsely charged with assault, his initial optimism is shattered. But what earns him a place on this list is his gradual return to compassion despite having every reason to remain cynical.
Where Tanjiro from Demon Slayer never wavers in his empathy, Naofumi must rediscover his. Both characters share an unbreakable drive to protect others, particularly those who can’t defend themselves. Through caring for Raphtalia and other companions, Naofumi slowly rebuilds his capacity for trust. His actions reveal the good-hearted hero he truly is — someone who, like Tanjiro, will put himself at risk to save even those who’ve wronged him.
6) Leonardo Watch (Blood Blockade Battlefront)
Dropped into Hellsalem’s Lot, the ordinary human Leonardo Watch somehow maintains a cheerful disposition that rivals Tanjiro’s. Gifted with the “All-Seeing Eyes of God” at the cost of his sister’s sight, Leo navigates a city where cosmic horrors and everyday humans coexist.
Both characters find themselves thrust into supernatural worlds they never asked for, yet they approach their new reality with resilience and compassion. Leo’s ability to see the good in creatures that terrify others mirrors Tanjiro’s empathy toward demons. Despite constant danger and witnessing unimaginable events, Leo never becomes jaded or cruel. His optimistic persistence makes him the heart of Libra, just as Tanjiro’s compassion anchors the Demon Slayer Corps.
7) Shigeo “Mob” Kageyama (Mob Psycho 100)
Behind Mob’s expressionless face lies an optimism that rivals even characters like Tanjiro from Demon Slayer. This middle-school psychic possesses devastating powers that could easily turn him into a villain — yet he chooses kindness at every turn. Despite being used by his mentor and bullied by classmates, Mob keeps an almost frustrating belief in human goodness.
Like Tanjiro from Demon Slayer, Mob’s strength comes from his heart rather than his abilities. Both characters exert unusual restraint with their powers, using them to protect rather than destroy. Mob’s determination to see others as inherently good — even when they’ve shown him cruelty. Their shared philosophy that violence should be the last resort sets them apart from typical shonen protagonists.
8) Atsushi Nakajima (Bongu Stray Dogs)
Orphaned, abused, and convinced of his worthlessness, Atsushi still somehow maintains the kind of optimism that would make characters like Tanjiro from Demon Slayer proud. Despite discovering he harbors a were-tiger inside him, this silver-haired detective approaches others with cautious hope rather than the suspicion his traumatic past would justify.
These characters transform individual catastrophe into an ambitious force for good. Atsushi’s gradual journey from humility to self-acceptance parallels Tanjiro’s growth throughout Demon Slayer. Like Tanjiro, who sees the humanity in demons that others would simply kill, Atsushi recognizes the complexity in people labeled as villains. His persistent belief that someone’s past doesn’t determine their future reflects Tanjiro’s compassionate worldview.
9) Asta (Black Clover)
Asta was born without magic in a magical world, yet you’d never find a more optimistic underdog like him. This clamorous, ever smiling protagonist conveys Tanjiro’s unbreakable spirit in the face of plainly impossible odds. Despite endless mockery and bias, Asta follows his dream of becoming the Wizard King with a determination.
Like Tanjiro from Demon Slayer, Asta rejects letting others see his limitations. Both characters remake their disadvantages into strengths — Tanjiro’s heightened sense of smell, Asta’s anti-magic abilities. Their shared quality of persisting despite everyone telling them to give up makes them spiritual brothers across different anime universes. Asta’s endless optimism isn’t blind to reality; like Tanjiro, he admits his flaws while not being limited by them.
10) Izuku Midoriya (My Hero Academia)
No character exemplifies the same determined optimism as Tanjiro from Demon Slayer quite like Deku. Born as a quirkless in a superhero society, Izuku Midoriya experienced years of bullying and dismay. Yet somehow, this green-haired hero held a heart so genuinely good that it caught the attention of the world’s greatest hero, All Might.
These main characters face problems where bitterness would be explained, yet choose empathy instead. Like Tanjiro, who sees humanity in demons, Deku senses the hero in everyone — even former bullies and villains. They willingly violate their bodies to save others, showing that true heroism lies in self-sacrifice. Their optimism is an active force that changes those around them and reshapes their individual worlds.
Conclusion
These 10 characters like Tanjiro from Demon Slayer, prove that maintaining optimism is all about choosing to light a candle in darkness. Tanjiro and these similar heroes are so compelling with their power levels and also their stubborn insistence on kindness. Each character on our list demonstrates that sometimes, the most revolutionary act is refusing to let suffering harden your heart.
