Why Did Masaomi Kida Leave Durarara?

Celty Sturluson from 'Durarara!!' is such a standout character—headless, motorcycle-riding, and utterly chaotic in the best way. I went digging around for spin-offs because I couldn't get enough of her, and turns out, there's no dedicated manga just for her. But! She does appear in the sequel light novel series 'Durarara!! SH,' where her antics continue alongside the rest of Ikebukuro's weirdos. The original manga adaptation of 'Durarara!!' covers her arc pretty well, though, especially her relationship with Shinra, which is equal parts hilarious and heartwarming. If you're craving more Celty, the anime OVAs also sprinkle in extra moments with her. Honestly, she’s one of those characters who steals every scene she’s in, spin-off or not. I’d kill for a spin-off just about her delivery service shenanigans or her daily life adjusting to human quirks. The closest we get is fanworks—some doujinshi dive into her backstory or imagine what her life in Ireland was like. Until an official spin-off drops (fingers crossed), I’ll just keep rewatching her scenes and cackling at how she tries to 'blend in.'

One thing that always hooked me about 'Durarara!!' is how Celty's presence is felt more than her words — and yet two actresses give that presence life. In Japanese, Celty Sturluson is voiced by Miyuki Sawashiro. Her delivery is subtle: mostly soft breaths, clipped noises, and that calm, strange aura that fits a headless courier perfectly. Sawashiro manages to make silence and tiny sounds expressive, which suits Celty's odd blend of stoicism and loneliness. In the English dub, Caitlin Glass provides Celty's voice. Glass leans into the enigmatic vibe too, using minimal but purposeful vocalizations and a slightly mechanical tone when Celty speaks through the helmet. Both performances are less about long speeches and more about texture — the helmeted whispers, the quiet frustration, the warmth under the helmet when she’s with people she trusts. I love listening to the differences: Sawashiro’s subtle warmth versus Glass’s crisp, hushed clarity. They make Celty feel alive without having her say much, and that still gives me chills every time I watch her ride through Ikebukuro.

My take is that 'Durarara' spreads its weight across a surprising ensemble, but a handful of characters clearly carry the heaviest emotional and narrative loads. Mikado Ryuugamine sits at the center — his arc is the slow-burning transformation from shy country kid to someone who wrestles with leadership, guilt, and the ethics of anonymity. Watching his internal moral tug-of-war unfold is fascinating because it’s not just plot; it’s identity. He catalyzes events and then has to live with their consequences, which makes his growth feel earned rather than manufactured. Next up, Anri Sonohara has one of the deepest, most tragic evolutions. The Saika storyline alone turns her from a quiet girl into someone entangled with supernatural danger, emotional manipulation, and the burden of being both victim and potential destroyer. Her relationships — especially with Mikado, Masaomi, and the shadowy forces around Ikebukuro — force her into decisions that redefine her agency. Her arc explores trauma, trust, and the way people cope with a part of themselves that wants to hurt others and to be loved. Masaomi Kida completes the trio of heavyweight arcs: his cheerful facade and gang-leader antics hide a history tied to the Yellow Scarves, betrayal, and loyalty. He’s the character whose past choices haunt his present, and his attempt to reconcile who he was with who he wants to be adds real stakes. On top of those three, Celty and Izaya loom large — Celty’s search for identity and Izaya’s manipulations ripple through everyone’s lives — but for me, the show’s emotional center sits with Mikado, Anri, and Masaomi. I still find myself thinking about their choices weeks after rewatching, which says a lot.

Masaomi Asahina, that charming and slightly chaotic character from 'The Day I Became a God,' is brought to life by the incredibly talented Kaito Ishikawa. I first noticed Ishikawa's voice work in 'Haikyuu!!' as Tobio Kageyama—his range is insane! He can switch from cold and intimidating to warm and goofy effortlessly, which makes him perfect for Asahina's mix of confidence and vulnerability. Ishikawa has this knack for injecting just the right amount of sarcasm and sincerity into his roles, and it’s no different here. What’s fun is comparing his performance as Asahina to other roles like Genos in 'One Punch Man' or Rei in 'March Comes in Like a Lion.' The dude’s versatility is unreal. I’ve followed his career for years, and it’s been a joy hearing him grow into more nuanced characters. Asahina’s flamboyant yet layered personality could’ve easily felt one-note, but Ishikawa adds depth with every line. Also, his chemistry with the rest of the cast—especially Aoi Yuki as Hina—is electric. Voice acting doesn’t always get the spotlight it deserves, but performers like Ishikawa remind me why it’s such a vital part of anime.

The main character in 'Durarara' is Mikado Ryūgamine. He's a seemingly average boy who moves to Ikebukuro, a district in Tokyo, at the invitation of his childhood friend, Masaomi Kida. This boy is way more than he appears to be, though. Big city life is a far cry from his rural upbringing, and Mikado finds himself in the middle of the bizarre supernatural events that constantly occur in Ikebukuro.

One of the things I love about 'Durarara!!' is how it blurs the line between light novels and anime adaptations. The series actually started as a light novel written by Ryohgo Narita, with illustrations by Suzuhito Yasuda. It first hit the shelves in 2004 under Dengeki Bunko, and let me tell you, the novels are just as chaotic and vibrant as the anime. Narita has this knack for weaving together huge casts of characters, and the light novels dive even deeper into Ikebukuro's underground than the anime could. I picked up the first volume after watching the show, and it felt like uncovering deleted scenes from my favorite movie—except there were entirely new subplots and character backstories. The anime covers the first three novels in its first season, but there are way more books out there if you crave extra Celty shenanigans or Shizuo’s absurd strength feats. What’s cool is how Yasuda’s art style evolved over the novels—it’s got this gritty yet playful vibe that perfectly matches the story’s tone. The novels also introduce characters like Vorona much earlier, which makes her anime debut less abrupt for readers. If you’re into unreliable narrators and urban legends, the books sprinkle even more folklore references throughout. Sometimes I wish the anime had kept certain monologues intact, like Izaya’s inner musings about humanity, but hey, that’s what the novels are for. The way Narita plays with perspective—jumping between characters mid-chapter—works surprisingly well in print, though the anime’s soundtrack definitely adds to the madness.

Oh, diving into 'Durarara' spin-offs feels like exploring Ikebukuro's back alleys—there’s always more than meets the eye! Beyond the main series, Ryohgo Narita expanded the universe with 'Durarara!! Saika Arc,' focusing on Celty’s iconic motorcycle and the cursed sword Saika. It’s a wild ride that delves deeper into the supernatural underbelly of the city. Then there’s 'Durarara!! Yellow Scarves Arc,' which spotlights the gang dynamics and Mikado’s descent into chaos. Both spin-offs weave seamlessly into the original’s tapestry, adding layers to characters like Izaya and Shizuo without overshadowing their main story arcs. What’s fascinating is how these side stories mirror the anime’s episodic chaos—each arc feels like a standalone vignette yet contributes to the overarching madness. If you loved the tangled relationships and urban legends of 'Durarara,' these novels are like uncovering hidden gossip at Russia Sushi. Just don’t expect Celty to find her head anytime soon!

Celty didn’t just wake up one morning and decide to be mysterious — there’s a whole tragic, mythic thread behind why she’s the headless rider in 'Durarara!!'. She’s a Dullahan, a kind of Irish fairy who normally carries her own head. At some point her head was taken from her — stolen by human hands that coveted it, whether out of greed, curiosity, or some darker game. That theft forced her out of her old life and sent her chasing the missing piece of herself. She tracked the head across countries and wound up in Ikebukuro, where the city's rumors and crowds are perfect cover. Without her head she learned to manifest a shadow that can take shapes — most famously a black, roaring motorcycle she rides through the night. There’s also the human connection: Shinra, a doctor who found her and started helping her search, becoming a kind of anchor in a city that treats her like a legend. The series blends folklore with urban loneliness; Celty’s literal lack of a head becomes a powerful symbol of searching for identity, and her quiet determination is what turned her into the headless rider everyone whispers about. I always get a little shiver thinking about how lonely and yet resilient she is.
