⚡Characters!
・Qtie (CV:Nanahira)
The main character. A hikikomori. She suffered too much irl that she’s become a little (very) fuzzy in the head. Her obsessive love for the fictional character “Yunyun” is for sure an illness. Her overly “high” state from overdosing denpa songs causes her to propagate Yunyun love. Will there really be a happy end for such a degenerate otaku?
・Yunyun (CV:Haruko Momoi)
A fictional character that loves Qtie. A very much angelic devil. She will speak to Qtie through the monitor screen. Whilst the truth is unknown, most likely, she is just a figment of Qtie's imagination. It’s joever for her.

How much does Yunyun Syndrome!? Rhythm Psychosis for PC cost right now?
Yunyun Syndrome!? Rhythm Psychosis for PC starts at €3.03 (€3.40 with fees) at Key4Games, 72% under the €12.25 (no fees) of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €7.25 (€7.91 with fees) at Driffle.
That €3.03 (€3.40 with fees) already includes the GOCDKEYS16 coupon, so apply it at checkout or the store will show you a higher price.
With 19 offers across 12 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.
Is it worth buying the Steam Key for Yunyun Syndrome!? Rhythm Psychosis now or waiting?
That €7.25 (€7.91 with fees) key is expensive for what it usually costs.
- Those €7.25 (€7.91 with fees) are 17% above what it usually costs, measured on the store price.
- 11 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
- Across the 200 days we have tracked it, it has only been pricier than today on 8 days. The lowest it has ever cost is €5.78.
Worked out from 1,802 daily records of the Steam Key for Yunyun Syndrome!? Rhythm Psychosis across 11 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
Are these stores safe to buy Yunyun Syndrome!? Rhythm Psychosis from?
One caveat worth €0.32 (€0.10 with fees): the €3.03 (€3.40 with fees) at Key4Games is the cheapest, but that store carries only 37 Trustpilot reviews, so there is barely any track record behind it. Difmark sells the same shared account for €3.35 (€3.50 with fees) — €0.32 (€0.10 with fees) more — backed by 14.2k reviews and a 4.1 out of 5, which is a small premium for a seller thousands of buyers have already tested.
Which Yunyun Syndrome!? Rhythm Psychosis format should you buy?
With the shared account at Key4Games you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Driffle costs €4.22 (€4.51 with fees) more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
The 5 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
Can you activate Yunyun Syndrome!? Rhythm Psychosis in US?
17 of the 19 offers work on US — the Global ones plus the ones issued for your own region.
Why is there such an expensive Yunyun Syndrome!? Rhythm Psychosis offer?
One listing is worth ignoring: the Steam gift that G2A has at €19.01 (€19.30 with fees) is more than 5 times the cheapest offer and is not what this game costs. The number to work from is €7.25 (€7.91 with fees) at Driffle.
