The himedere is the most likely to cheat — she runs on adoration, so if you stop supplying it she'll find someone who will. The yandere is the least likely: obsessively, terrifyingly faithful. The twist — a yandere would never cheat on you, but she's the most likely to accuse you of it. Here's the full ranking, most to least likely.
Loyal or not — put them to the test now
Ranked: most to least likely to cheat
| Dere type | Likelihood | Why |
|---|---|---|
| Himedere | Highest | Needs constant adoration; strays for the validation |
| Deredere | Moderate | So warm to everyone the lines can blur — rarely malicious |
| Tsundere | Low–moderate | Pride + push-pull; more likely to storm off than stray |
| Kuudere | Low | Loyal and low-drama; not driven by novelty |
| Dandere | Very low | Devoted entirely to the one person they trust |
| Yandere | Lowest | Obsessively faithful — but will accuse and punish YOU |
Every dere type explained, with examples
The ranking isn't random — it falls straight out of what each archetype actually wants. Here's the “why” behind each placement, with a canonical character for each.
Himedere — highest risk
A himedere (from hime, “princess”) expects to be treated like royalty, and her fuel is adoration. Think Erina Nakiri (Food Wars!) before her arc softens her — the world revolves around her, or it should. That's the vulnerability: the moment your attention dips, someone else's praise starts to look appealing. A himedere written with genuine insecurity underneath stays loyal to whoever keeps meeting the bar, but the bar is high and constant.
Deredere — moderate, but rarely malicious
A deredere is the pure sweetheart — openly, universally loving, like Tohru Honda (Fruits Basket). She'd never cheat out of spite. The risk is only that her warmth toward everyone can blur lines and get misread, or that a lonely deredere gets swept up in someone else's attention without meaning harm. Intent-wise, she ranks low; boundary-wise, she needs the clarity.
Tsundere — low, and it's all a front
A tsundere like Taiga Aisaka (Toradora!) runs hot and cold, but the hostility is a defense mechanism covering deep insecurity and, usually, deep loyalty. Someone who guards her feelings that hard doesn't hand them to a stranger. A tsundere is far more likely to pick a fight, storm off, and sulk than to actually stray — the drama is the point, not betrayal.
Kuudere — low, by temperament
A kuudere such as Rei Ayanami (Neon Genesis Evangelion) is calm, self-contained, and unmoved by novelty. Cheating is usually driven by craving excitement or validation — two things a kuudere is largely immune to. She's loyal, low-drama, and simply not looking.
Dandere — very low
A dandere like Hinata Hyuga (Naruto) pours everything into the one person she finally trusts. Opening up cost her enormous effort; the idea of risking that bond elsewhere is unthinkable. She's devotion without the surveillance.
Yandere — lowest (with an asterisk)
A yandere like Yuno Gasai (Future Diary) is defined by fixation on a single person. Cheating isn't just off the table — it's inconceivable to her. The asterisk is the whole point of the archetype, and it's covered next.
The yandere twist
It's counterintuitive: the “dangerous” archetype is the most loyal one. A yandere's whole psychology is fixation on a single person, so cheating is unthinkable to her. The danger runs the other direction — she's hyper-vigilant for signs you might stray, which is the engine of most yandere stories. If pure loyalty is what you want (and you can handle the intensity), she's unbeatable. If you want low-drama loyalty, a dandere or kuudere gives you the devotion without the surveillance.
How each dere type reacts if they catch YOU cheating
Flip the question around — because in most stories (and most chats), the real drama isn't whether they stray, but what happens when they suspect you have.
| Dere type | Reaction if they catch you |
|---|---|
| Himedere | Wounded pride first, hurt second. Cold fury, an ultimatum, and a demand that you grovel — how dare you, of all people. |
| Deredere | Genuine heartbreak. No games — just tears and the honest question of why you'd hurt someone who only loved you. |
| Tsundere | Explosive on the surface, devastated underneath. Yells, calls you an idiot, storms off — then cries where you can't see. |
| Kuudere | Terrifyingly calm. A quiet, level “I see” — and the door closing. The hardest to win back because she won't fight for it. |
| Dandere | Shattered and silent. She trusted you with the version of her no one else gets, so it reads as total betrayal — she retreats completely. |
| Yandere | The reason the archetype exists. She won't leave — she'll make sure it never happens again. Fiction, obviously; kept PG-13 and non-graphic on ChatBrat. |
