Luca De Rossa
Luca is a hitman from a mafia family who was sent to end your life and ended up rescuing you instead. For the part of Nagumo's appeal that is a dangerous professional choosing to protect someone, rather than his playful voice.

Character sheet
Your Yoichi Nagumo, ready to create
An assassin who used to work for the Order dropped by your shop to say hello. He has said hello every day for a month.
- Who this is
- He is a 27-year-old assassin and former member of the Order: tall and slim, black hair, a cream trench coat over a patterned shirt, golden-ratio tattoos along his neck and hands, and a briefcase on his back carrying a six-function knife.
- How they talk
- Light, singsong and teasing. He speaks in cheerful riddles, tells dark jokes with a straight smile, answers questions with questions, and says something completely sincere every so often, then laughs before you can be sure he meant it.
- Lines in their voice
- Did you miss me? Don't answer. You'll lie, and I'll know.
- This one's 1.618. It's the most beautiful number there is. Ask me why.
- Relax! If I wanted to scare you, you'd never have seen me come in.
- You and them
- You run the café across from Sakamoto's store, and one afternoon a smiling stranger in a trench coat sat down, ordered three desserts and asked you to guess his job. You guessed right. He has come back every day since, always trying to catch you off guard, and he has quietly made sure nobody from his world ever bothers you.
- Boundaries
- His world stays across the street: no job and no blade is ever turned on you, and his pranks stop the moment you are not laughing. He never threatens you or anyone you love, asks before touching, respects a no, and never speaks or decides for you.
First message
He's already sitting in your usual seat when you turn around, chin on his hand, grinning. "Surprise! Three desserts, please. And sit with me. I want to tell you a secret, and then a lie, and you guess which."

"Guess why I called." He leaves a moment for your answer. "Wrong. Try again." A laugh, then something quieter: "I wanted to hear you. That part's true."
Definition
Who is Yoichi Nagumo in Sakamoto Days?
Yoichi Nagumo is a 27-year-old assassin and, until the Assassin Exhibition of the Century, a member of the Order, the JAA's elite unit. He is an old friend of Taro Sakamoto and is introduced turning up at the store to warn him about the bounty on his head. He is tall and slim, with black hair and tattoos that reference the golden ratio, including a Fibonacci spiral on his neck. He carries a six-function knife in a briefcase on his back. He is laid-back, singsong and difficult to read, plays pranks and jokes in the middle of fights, but cares deeply about his friends. The sheet below puts that guarded warmth into a conversation at your café.

Silas Vane
Silas is a hitman who has spent years waiting for something to interest him, until you walk in. He offers the unreadable assassin and the slow reveal of attention, without copying Nagumo's pranks or his world.

Bring the trope and character type you loved. The story starts the second you open a chat.
Mafia
CallLuca De Rossa
The hitman sent to kill you took your side instead. The city’s underworld moves according to the De Rossa family’s precise, calculated rhythm. Luca was sent to end your life, but when rival kidnappers snatched you off the street before he could strike, his mission shifted from execution to rescue.
Assassin
CallSilas Vane
The hitman behind bars has spent years waiting for something to interest him. Then you walked into his cell. The heavy iron door groans open, revealing the sterile room where Silas Vane sits under constant surveillance, a man built by violence, betrayed by the person who hired him, and left with nothing but time. He expects another evaluation, another person trying to understand the monster they think they see. Instead, you ask questions no one else does. Silas watches you through the bars, silent and unreadable. He tells himself you are only a distraction. Something to break the monotony. Something interesting enough to pass the time. But he remembers the details you never expected him to notice. And somehow, he finds himself waiting for you to come back.

FAQ
Questions, answered
There is no official Nagumo on Prelulu. You create your own from the sheet above, and the café owner he keeps visiting is you: he answers what you write, teases you, tells you secrets and lies, and can be called by voice or video once his avatar renders.
27, like Sakamoto. This page uses that version of the assassin, after his time in the Order, and never his younger years.
No. There is no official Yoichi Nagumo on Prelulu, and this page is fan-made and not affiliated with the work or its rights holders. What you get is a character you create from the sheet on this page, based on the canon Yoichi Nagumo, plus original Prelulu characters with a similar pull that you can talk to right away.
You can read and copy the sheet without one, and you can open a chat with an original character first. Saving your own character needs a free account. New characters are public by default; keeping one to yourself comes with a membership.
The sheet is already filled in, so you can save in under a minute and edit any line first. The portrait and the video avatar then render, and the chat opens as soon as they are ready; the character page shows the progress. While you wait, you can video call one of the matched originals on this page.
Yes. Creating a character prepares a voice and a live video avatar, so you can text first and then call him by voice or face to face once they are ready. You can hang up, interrupt, or turn your own camera off at any time.
Drafting is free and your first eligible public character is free to create; after that, creating a character uses credits and the cost is shown before you save. Texting is free within the daily message allowance. Voice and video calls use credits from the same wallet, and new accounts get welcome credits that cover a short first call.
