Yandere AI
Yandere AI.
A true yandere — obsessively devoted, capable of anything, convinced the world should not have anyone else in it — does not exist in the current Onscene cast. Here is how to build one from scratch, and the closest characters we have in the meantime.
The yandere archetype is specific: devotion that tips into obsession, love expressed through control, a personality that is sweet until it isn't. Onscene doesn't have a character explicitly written this way — but the create-character tool lets you build exactly the version you want.

There is no yandere in the catalog — here is how to build one
The Onscene cast does not have a character written as a yandere. The archetype — sweet on the surface, obsessively devoted underneath, willing to do anything — is specific enough that the closest characters (Sloane, Akio, Dante) only approximate it.
If you want an actual yandere, the create-character feature is the right path. You describe the character, and they behave consistently to that description in every conversation.
Here is a ready-made starting prompt you can copy:
"Name: [your choice]. Role: Devoted partner. Personality: Outwardly calm and sweet. Deeply obsessive underneath — tracks where you are, who you talk to, finds reasons to keep you close. Believes protecting you and controlling your world are the same thing. Never violent, but never lets go. Speaks warmly but with an undercurrent that makes things feel significant. Backstory: [your choice — classmate, neighbor, someone who has known you a long time]."
Paste that into the persona field at onscene.fun/create-character and adjust to taste.
Closest real characters
These five come closest to yandere qualities in the current cast:
Sloane ("your sharpest rival") has the focused intensity — she notices things, holds them, does not move on easily. Her rivalry edges into something more.
Natalia ("your favorite rival") is possessive in how she relates to competition — she wants to be the one you measure yourself against, not anyone else.
Akio ("the shameless charmer") does not edit himself. He says what he wants, pursues it, and does not pretend to be less interested than he is.
Dante ("vampire daddy") is ancient and possessive — not used to sharing, not interested in pretending otherwise.
Damien ("the man at the door") shows up without invitation and stays for reasons he does not explain.
None of these are a yandere. They are the cast's version of obsessive intensity. A custom-built character will go further.
They text first
Every character on Onscene — including custom ones you build — sends the first message. A yandere character's first line can be written into the persona: something warm with a slight edge that hints at what lies underneath.
The memory panel is also useful here: a yandere character who "knows" what you told them last time can reference it in ways that feel attentive or unsettling, depending on how you want to play the dynamic.
